NOVITATES ZOOLOGICAE Vol. XXVH. JUNE 1920. No. I. SUPPLEMENTAL NOTES TO MR. CHARLES OBERTHUR'S FAUNE DES LEPIDOPTERES BE LA BARBARIE, WITH LISTS OF THE SPECIMENS IN THE TRING MUSEUM. {Continued from Vol. XXIV. p. 409 (1917).) By Lord Rothschild, F.R.S., Ph.D. (Plates XIV— XVII.) THE long-expected volume of Mr. Oberthiir's Etudes de Lepidopterologie Comparee, containing the Noctuidae of Algeria, has at last appeared. The date on the wrapper is Octobre 1918, but the volume was only, received in March 1919, so the date of publication for the new names published therein must be taken as 1919. It calls for various remarks. Mr. Oberthiir has adopted Guenee's system of classification of the Noctuidae. Now, although the aim of Science is to establish uniformity of nomenclature and a single classificatory system, it is impossible to forbid the use of any system ; we can only regret, therefore, that such a renowned entomologist as Mr. Oberthiir adopts systems and methods abandoned by the majority of modern workers in Entomology. But while we can only regret this retrograde policy of Mr. Oberthiir, we can and must strongly deprecate the reasons he has and gives for not adopting Sir George Hampson's classification. Whatever other objections Mr. Oberthiir may have to the British Museum classifica- tion, he lays stress on one only, namely he harps upon the rather unfortunate error made by Sir George Hampson in placing Phragmatobia breveti berth, in the genus Maenas. This error has long ago been acknowledged by its author. Mr. Oberthiir makes great capital out of the aquatic habits of certain American species of Maenas as opposed to the desert habitat of bzeveti, quite ignoring the fact that the genus Maenas contains many African and Indo-Malayan species as well as American, and these are, as far as we know, non-aquatic in their habits. Sir George Hampson was misled by the somewhat aberrant neuration of P. breveti, which is almost identical with that of Maenas ; moreover, breveti is not a Tricho- soma as Mr. Oberthiir asserts, but a true Phragmatobia, The abortive wings of the $ are not a generic character, but only specific, as can be seen in the case of Cymbalophora rivularis Men., which has a 9 with abortive wings, while Cymba- lophora pudica Esp. and C. oertzeni Led. have the $ full winged. The aquatic habits of the larva are also only of secondary importance, for in the genus Spilosoma (Diacrisia) we find Spilosoma (Diacrisia) metalhana with a free swimming aquatic larva, while sannio and amurensis, which are very closely allied, 1 2 NOVITATES ZOOLOGICAE XXVII. 1920. have ordinary terrestrial larvae. We cannot condemn a whole system simply because its author made one rather striking error. I have adopted the British Museum classification because so far there does not appear to be a better one. According to this classification, the family Noctuidae is divided into fifteen subfamilies, viz. : Agrotinae ; Hadeninae ; Cuculliinae ; Zenobiinae (Acronyctinae) ; Era- striinae ; Phlogophorinae (Euteliinae) ; Odontoninae (Stictopterinae) ; Sarrothri- pinae ; W ' ester manniinae (Acontiinae) ; Catocalinae ; Diphterinae (Mominae) ; Phytometrinae ; Noctuituie ; Polypogoniiiae (Hypeninae) ; and Hyblaeinae , Of these fifteen subfamilies, two, namely, the Diphterinae and Hyblaeinae l have no representatives in Algeria, and three others, the Phologophorinae, Odontoninae, and Sarrothripinae, have only one representative each. Sir George Hanipson, who is a great stickler for classical correctness, in the case of names forming subfamily appellations in which the ending is in "ia,'' insists on the subfamily being formed with the ending " ianae," such as Cucullianaehom Cucullia. The International Rules, however, say the sub-family term is to be made by the addition of the ending " inae " to the word, and so I have made the families Cuculliinae, Zenobiinae, Erastriinae, and W estermanniinat end in " iinae " instead " ianae." I am taking the species, in the first place, in the order Mr. Oberthiir has placed them in, for the purpose of critical remarks where these may be necessary ; but at the end I am giving a full list of the species and genera in the order followed by the British Museum classification. I am giving a list of the Algerian, Tunisian, and Moroccan specimens in the British Museum as well as those at Tring. 1. Bryophila petrea Guen. Bryophila petrea Guenee, Hint. Nat. Ins. Spec. Gen. Lipid, vol. v. Noct. vol. i. p. 25. No. 22 (1852) (Andalusia). Mr. Oberthiir records this species from Maafa and Lambessa ; we have received 35 from Guelt-ea-Stel, 1 from Batna, and 1 El Kantara. There are in the Tring Museum 18 (J <$, 17$$ from Guelt-es-Stel. This series shows considerable variation in the forewings, some being pale grey with hardly any markings, while others are of a deeper brighter grey with conspicuous black markings, and a few have such dark grey forewings that the black markings show up hardly darker than the ground colour. 1 ^Environs de Batna, 1914 (A. Nelva) ; 1 cj El Kantara, August 1917 (V. Faroult). 2. Bryophila aerumna Culot. Bryophila aerumna Culot, Xoct. et Gtom. d'Eur. pt. i. vol. i. p. 131, pi. 22. f. 17 (1912) (Giryville). Monsieur Culot quotes this and a number of other new species as "Oberth." because he adopts the names suggested by Mr. Oberthiir in his letters to him ; while Mr. Oberthiir quotes them as "Culot (secundum Oberthiir)." Both these methods are wrong ; the correct way of quoting is Bryophila aerumna Culot ; but if it is thought desirable to mention Mr. Oberthur's connection with these species, it should be done as follows: Bryophila aerumna Culot (Oberth. in lilt.) NOVITATES ZOOLOGICAE XXVII. 1920. 3 There are at Tring 32 specimens of this species from Sidi-bel- Abbes, September 1917 (M. Rotrou) ; Sebdou, September 1918 (P. Rotrou) ; Perregaux, September 1915 (V. Faroult) ; AIn Draham, September 1911 (V. Faroult). [Bryophila aeton Culot = Catamecia mauretanica Stdgr. Calamecia jordana var. mauretanica Staudinger and Rebel, Cat. Lepid. Pal. Faun, pt. i. p. 213. No 2192i) (1901) (Biskra). Bryophila aeton Culot, Noct. el Gtom. d'Eur. pt. i. vol. i. p. 132. pi. 22. f. 16 (1912) (El Outaya). Neither Mr. Oberthiir nor Mr. Culot have perceived that the type of aeton is only a heavily marked fine specimen of Catamecia mauretanica Stdgr.] 3. Bryophila divisa oxybiensis Mill. Bryophila oxybiensis Milliere, Rev. Zool. 1874, p. 242 (Cannes). Catamecia bryophiloides Rothschild, Novit. Zool. vol. xxi. p. 330. No. 194 (1914) (Guelt-es-Stel). The name divisa has one year's priority over that of pomula ; Esper being 1791, while Borkhausen is 1792. Pere Engramelle, it is true, is older, but he has " La Pomule " not pomula, so the date of pomula is that of Borkhausen, who latinised Pere Engramelle's name. In 1913 (Novit. Zool. vol. xx. p. 125, No. 52) I unfortunately identified some unicolorous grey specimens of this insect from the Oued Nca as Bryophila pineti Stdgr., which I then only knew from a drawing. I have now discovered this error, and I name these unicolorous specimens ab. unicolor ab. nov. The form of divisa oxybiensis most similar in coloration to typical divisa must bear the name ab. rufilincta Rothsch. (Novit. Zool. vol. xx. p. 125 (1913)), and the form with the basal two-thirds of the forewing below median fold black is ab. distincta Rothsch., and, lastly, the very dark form ab. saturatior Rothsch., both described on p. 125. We have at Tring 1 Hammam R'hira June 1916, 1 Alger January 1914 (V. Faroult) ; 27 c?c?, 21 $$ Oued Kca, June 1912 (E. H. and C. H.) ; 5 9 (1827). Both Warren's ab. pallida and my Borolia lacteicolor are the pale form of this insect. It is strange that this pale form is almost invariably smaller than the darker more strongly marked typical form. The series of Mauretanian examples at Tring consists of 319 specimens, 218 typical vitellina and 101 ab. pallida Warr. from Environs d'Alger, May 1908 (W. R., E. H., and K.

Mr. Oberthiir quotes Engramelle as the author, but Ernst and Engramelle when describing species not yet described only gave French names to their insects, and therefore they are quite inadmissible as authors, and the names given to their species by Hiibner and others must be quoted under their respective authors. As, however, that part of Hiibner containing his saucia was published in 1827 and Haworth's margaritosa in 1809, this latter name must be used for the present species. Although fairly widespread in Mauretania, it is much rarer than the last. We have 86 specimens from Ai'n Draham, August — September 1911 (V. Faroult) ; Oued Hamidou, June 1912 (V.

The lateral tail-feathers of tscherskii have also, as a rule, more black than in kamtschaticus, but sometimes appear not to be different in this respect. Woodpeckers are, of course, only occasional visitors on Bering Island, where there are no forests, so that it cannot be a real Woodpecker home. 119. Alauda arvensis pekinensis Swinh.

LESSER REDPOLL. Carduelis linaria cabaret (P. L. S. Mull.). B. of Berks, and Bucks, p. 110. Vict. Hist, of Bucks, p. 137. Winter visitor, but also breeds locally in small numbers. Kennedy only records this species as a winter visitor from about the end of November onwards, and never very common. Hartert on several occasions has noted small flocks in autumn and winter, and there are several specimens in the Tring Museum from Aston Clinton, near Tring, caught in October and November. Twenty-eight years ago Lord Rothschild observed it several times on the "flats" near Champneys Park in summer, and Grossman has recorded breeding on Berkhamsted Common, close to the Bucks, boundary. C. Oldham {in litl.) states that he has seen a few pairs every summer about the Herts .-Bucks, boundary near Berkhamsted, and adds that he also saw one at Mentmore on June 15, 1913, " uttering its trilling song in flight." The only part of the county where breeding is known with certainty to have taken place is the Thames Valley between Shiplake and Wraysbury. Many scattered pairs used to haunt the various " rod beds " by the river, nesting in most cases on the Berks, side, and sometimes several nests might be found within quite a small area. The late Major F. W. Proctor found many nests in this district between 1905 and 1914; not only in willows, but also in thorns, furze bushes, and small trees at some little distance from the river. Mr. E. E. Pettitt gives details (in Hit.) of half a dozen Bucks, nests found by him in the same district between 1909 and 1916, but adds that after the severe winter of 1916-17 none were met with. 20 (27).

In the old manuscript at Din ton Hall is an excellent figure of "ye Crossbill or Shellapple" which was shot there in 1782, with the following notes : " Is an inconstant visitor of this island and breeds in ye pine-forests of Germany and Switzerland ; it feeds on ye cones of those trees. It is a fact that it changes ye shades of its colour in different seasons of ye year from deep red to yellow and ye females which are greenish alter to different varieties of the same colour. Ten of these birds were shot and several others seen by ye Rev nd W. Goodall in ye Wilderness of Dinton Hall August 8 th ' 1791. They had been observed by the servants some weeks, tho' they mistook them for bull finches. Q >T had they bred there ? As some of ye males had not then gained their full j^lumage and one of ye females had not as yet a single yellow feather." It is, of course, well known now that the red plumage is that of the adult male, though peculiar ideas about the plumages of Crossbills prevail occasionally even now. Kennedy records occurrences at Drayton (about 1847), and also at Fulmer, Risborough, and Burnham Beeches, and mentions a hen bird seen near Eton in November 1867. More recently T. Marshall recorded this species in the Wycombe district in 1898 (Field, December 3, 1898, p. 897) ; while in December 1909 a flock of about thirty was seen at Fawley Court (H. Noble, Brit. Birds (mag.), vol. iii. p. 303). In March 1910 six were seen at Drayton Beauchamp (C. Oldham, i.e. p. 409), and several at Langley about the same time (H. Noble). A pair killed at Dinton, January 15, 1910, is in the County Museum (Edw. Hollis). The only definite record of breeding is that by Mr. R. Bulstrode (Brit. Birds (mag.), vol. vi. p. 60), who saw a flock of four or five birds near Gerrards Cross on March 27, 1910, and was shown a nest on April 1 which then contained four eggs. The young were still in the nest on April 23. 23 (37). CHAFFINCH. Fringilla coelebs coelebs L. B. of Berks, and Bucks, p. 31. Vict. Hist, of Bucks, p. 136. Resident, but numbers apparently augmented by immigrants in winter. Very common in all wooded parts of the county. Mr. A. Mayall found eight eggs in a nest near Burnham, from which six young were reared, in May 1919 (Brit. Birds, vol. xiii. p. 80). 24 (38). BRAMBLING. Fringilla montiMngilla L. B. of Berks, and Bucks, p. 106. Vict. Hist, of Bucks, p. 136. Winter visitor, sometimes in great numbers. The Brambling appears every winter, and has been observed from October to April, but generally between November and March. Numbers vary greatly, sometimes not many are observed, while in other years they are very numerous ; Hartert does not think that this depends on the severity of the winter — at least not in this country — but more on the amount of beech mast. From time to time 180 NOVITATES ZOOLOGICAE XXVII. 1920. enormous flights are observed. An influx of this kind took place in the winter of 1905-6, when the beech woods of the Chilterns swarmed with these birds, flocks of several hundreds being repeatedly seen. Considerable numbers were also present during the mild winter of 1919-20. 25 (40). HOUSE-SPARROW. Passer domesticus domesticus (L.). B. of Berks, and Bucks, p. 33. Vict. Hist, of Bucks, p. 136. Common resident. By far the most numerous of all birds in the county. One of the most obnoxious habits of this species is that of dispossessing the House-Martins of their homes. Sir. A. H. Cocks adduces some evidence that the Martins occasionally retaliate by killing the nestling Sparrows, but further evidence on the point is desirable (cf. Zool. 191G, p. 358). 26 (41). TREE-SPARROW. Passer montanus montanus (L.). B. of Berks, and Bucks, p. 32. Vict. Hist, of Bucks, p. 136. " A resident species, but noichere numerous and very local." The above words of Kennedy are still correct and well describe the status of this bird in Bucks. Kennedy reports a nest near Buckingham in a Sand- Martin's hole. He also mentions specimens killed near Datchet and Slough. From autumn to spring, however, Tree-Sparrows are common in the neighbour- hood of Wendover, Aston Clinton, Ivinghoe, where Oldham regularly observes them, usually feeding with House-Sparrows and Finches in farm-yards and stack- yards, and near Cheddington, but they are seldom seen in the summer. Mr. Oldham observed one near Cheddington May 10, 1908. Hartert has seen it near Aylesbury and Ovington. In the Thames Valley there are scattered colonies, which nest in the pollarded willows by the river-side, especially in the Maidenhead and Bray districts. Mr. Pettitt mentions a small colony at Horton. 27 (42). CORN-BUNTING. Emberiza calandra calandra L. B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 137. Resident, Not actually rare in the arable districts, but nowhere numerous, and not often noticed in winter. Kennedy (I.e.) says " it congregates in large numbers late in the autumn and is gregarious until the return of the spring." We have never seen large flocks in Bucks, or Herts. In the Thames Valley Mr. Pettitt notes it as breeding near Taplow, Slough, and the reservoirs on the Middlesex border. F. A. Monckton has recorded a case in which the song was heard in November near Eton {Field, November 14, 1908, p. 888). 28 (43). YELLOW BUNTING, or YELLOWHAMMER. Emberiza citaneUa citrinella L. B. of Berks, and Bucks, p. 30. Vict. Hist, of Bucks, p. 18. Resident. A common bird, but somewhat diminished in numbers since 1917. Mr. A. H. Cocks records a nest built in the side of a straw-rick, about 3 ft. 7 in. from the NOV1TATES ZOOLOGICAE XXVII. 1020. 181 ground at Skirmett (Zool. 1916, p. 352), but this is not a very infrequent occurrence. 29 (47). CIRL-BUNTING. Emberiza cirlus cirlus L. B. of Berks, and Bucks, p. 176. Vict. Hist, of Bucks, p. 138. Resident. The Cirl-Bunting breeds regularly in the Chiltern Hills district and neigh- bourhood. In winter it strays about, but apparently not usually very far from its breeding-grounds. The following are the localities from which we have evidence : Terriers End, near Tring (Chas. Oldham, evidently nesting) ; neigh- bourhood of Wendover (Hubert D. Astley, Oldham, Witherby, Hartert, nesting) ; Ashley Green, south of Berkhamsted, Coombe Hill, Chequers Court (Hubert I>. Astley, nesting) ; Drayton Beauchamp (4 . vi . 1864, nest found by H. H. Crewe, Field, 3 . xii. 1864, p. 384) ; Halton (skins of winter birds, eggs seen) ; Pitstone (caught in winter, H. H. Crewe) ; Ivinghoe (seen in winter, Hartert) ; downs between Princes Risborough and Wendover common, five males singing between Kimble and Wendover 4.vii.l910 (Chas. Oldham). In the Thames Valley it is of infrequent occurrence, but has been met with occasionally near Great Marlow. Mr. A. H. Cocks records one from Harleyford on January 26, 1884 (in lift.). The winter of 1917 has greatly diminished the number of Cirl-Buntings ; near Tring we have not heard or seen them since. 30 (53). REED-BUNTING. Emberiza schoeniclus schoeniclus L. B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 138. Resident, but breeding birds wander about in autumn. Not rare in suitable places on rivers and reservoirs. Breeds on the Tring and Halton Reservoirs, on the banks of the Thames, Colne, Chess, and Ouse, and in Stowe Park. In winter in small flocks, which haunt stack-yards and high- roads. Mr. E. E. Pettitt found a nest of this species in June 1905 at Wraysbury, which was placed in the crown of a pollarded willow ! He has also on two occasions met with Cuckoos' eggs in Reed-Buntings' nests in the county, both in 1908, in the Colne Valley. A very remarkable clutch of four eggs, pale blue without any markings, was taken by James Street at Mars worth Reservoir on May 9, 1910, and is now in the Tring Museum. 31 (56). SNOW-BUNTING. Plectrophenax nivalis (L.). Vict. Hist, of Bucks, p. 138. Winter visitor. Of somewhat rare and irregular occurrence in winter. The MS. in Dinton Hall mentions its occurrence there on January 8, 1776. Flocks have repeatedly been seen near Aston Clinton, and in 1895 near the Tring Reservoirs. On November 4, 1901, a male was shot at Drayton Lodge, Bucks., between Aston Clinton and Tring, by Mr. Henry Jenney. (February 22, 1894, another male was caught near Tring, between Tring and Aston Clinton, just in Herts.) Mr. C. H. Enison met with two on Ivinghoe Beacon on November 7, 1903 (Field, November 14, 1903, p. 844). 182 NOTITATES ZOOLOOICAE XXVII. 1920. 32 (61). WOODLARK. Lullula arborea arborea (L.). B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 139. Probably resident. Local and scarce. Observed in spring and summer near Fulmer, Beacons- field, Princes Risborough, Halton, and Chequers Court. 33 (62). SKYLARK. Alauda arvensis arvensis L. B. of Berks, and Bucks, p. 27. Vict. Hist, of Bucks, p. 139. Resident. Common on fields and meadows, from autumn to spring in flocks, which are probably partly composed of continental visitors. Breeds freely both in corn and grass land. An entirely buff- yellow variety was shot in December 1863 at Weston Turville (R. Tyrer, Zool. 1864, p. 8957). Such varieties are not rare and have been observed in many other places in England and elsewhere. 34 (67). TREE PIPIT. Anthus trivialis trivialis (L.). B. of Berks, and Bucks, p. 8G. Vict. Hist, of Bucks, p. 134. Summer resident. Not rare in wooded districts from April to September, but far from numerous in the Thames Valley, where, however, a few pairs may be found breeding in the Burnham and Taplow districts. 35 (68). MEADOW PIPIT. Anthus pratensis (L.) B. of Berks, and Bucks, p. 27. Vict. Hist, of Bucks, p. 134. Resident and winter visitor. Nests in lowland pastures : on the canal banks near the Tring Reservoirs, Halton, Aylesbury, Buckingham, Castlethorpe, Farnham Common, Burnham Beeches, and, according to Kennedy, near Eton. In winter and during migration periods in small flocks near the Reservoirs. In the Thames Valley it is best known as a winter visitor, only a few pairs remaining to breed. 36 (74). BLUE-HEADED WAGTAIL. Motacilla flava flava L. Once observed. " In a pasture bordering one of the reservoirs near Tring, on April 29, 1917, my sister-in-law detected a Wagtail differing in colour from the Ray's Wagtails with which it was consorting. As we looked down from the top of the reservoir embankment on the birds running to and fro in the short grass, it was an easy matter to distinguish the stranger by its blue-grey crown and nape, the con- spicuous whitish-buff superciliary stripe, the less distinct streak of the same colour through the ear-coverts, and the buff wing-bars. The upper parts and ear-coverts were greyish-brown, the breast and belly pale yellowish-buff passing into bright sulphur- yellow on the under tail-coverts. I cannot say positively to which subspecies of Motacilla flava the bird (a hen) belonged, but the blue- grey crown and the pale ear-coverts point to M. f. flava, the subspecies, apart from Novitates Zooloqicae XXVII. 1920. 183 M. j. rayi, most likely to occur" (Chas. Oldham, Brit. B. vol. xi. p. 20, 1917). There is also a female in the County Museum, found dying near Aylesbury, June 2, 1911 (Edwin Hollis, in litt.). 37 (79). YELLOW or RAY'S WAGTAIL. Motacilia flava rayi(Bp.). B. of Berks, and Bucks, p. 85 (not 58). Vict. Hist, of Bucks, p. 134. Summer resident. Not a common bird, but more frequent in low-lying meadow land and in the neighbourhood of rivers, such as the Thames and Ouse. 38 (80). GREY WAGTAIL. Motacilia cinerea cinerea Tunst, B. of Berks, and Bucks, p. 26. Vict. Hist, of Bucks, p. 134. A breeding species in very small numbers in the Chess Valley, otherwise winter visitor, not common. The first mention of the breeding of this species in Bucks by John Gould occurs in Jardine's Contr. to Ornith. 1849, p. 137, and is repeated in his Birds of Great Britain, vol. iii. p. 49 (1873), where he states that for many years he has been aware of the breeding of the Grey Wagtail in the Chess Valley, and that when the Duke of Bedford " favoured him with a day's fishing," he found the nest on a wall of Mrs. Dodd's beautiful garden, where it always nested. Another pair also bred at Latimer, but in this case he did not find the nest. R. B. Sharpe, in his articles on the " Birds of Cookham," (Quart. Mag. High Wycombe Nat. Hist. Soc. vol. ii. p. 49, 1869), alludes to Gould's discovery of this nest in- a rose bush against the wall, and the fact of the male bird being found on the four eggs. He also says that another pair bred at Elliot's Mill, two and a half miles up stream. Clark Kennedy (I.e.) was apparently unaware of Gould's observations, but says that a few have been procured on the Thames in summer, though it is better known there as a frequent winter visitor. Bryant Burgess, however, informed him that it bred annually on the banks of the Chess. Hartert did not meet with it at Latimer in 1902, but more recent observations by the Duchess of Bedford and Mr. W. Bickerton show that it still frequents its old haunts at Chenies. near Sarrat Mill, some distance below Latimer, where, however, it was not found in 1918, while no observation took place in 1919.* To other parts of the county it is only known as a winter visitor. Mr. C. Oldham states that it frequents the reservoirs, canals, and water-cress beds of North Bucks in small numbers regularly from early September to mid-March. The Rev. H. D. Astley has recorded it from Chequers Court, and it is met with every winter in the Thames Valley. 39 (81). PIED WAGTAIL. Motacilia alba lugubris Temm. B. of Berks, and Bucks, p. 26. Vict. Hist, of Bucks, p. 134. Resident, but a good many move southwards in the autumn and return in early spring. A common bird, and widely distributed. * The breeding-place near Sarrat Mill, close to Chenies, is just a stone's throw or so outside Bucks., in Herts., while Latimer and Chenies are well within the Bucks, boundary. 184 N0Y1TATES ZOOLOGICAL XXVII. 1920. 40 (82). WHITE WAGTAIL. Motacilla alba alba L. B. of Berks, and Bucks, p. 134. Rare on passage ; has apparently once bred. On June 17, 1902, Hartert and Arthur Goodson went along the River Chess, near Latimer, in search of the Grey Wagtail. They failed to find the latter, but saw a pair of Wagtails feeding young which seemed to have quite grey backs, and which they took to be M. alba alba. A few hundred yards away they observed M. alba Ittgubris. On subsequent visits later in the year and in 1903 and l!iii4 Hartert failed to see any grey-backed birds. Recently Mr. Chas. Oldham has observed the White Wagtail in spring, though not nesting. On May 5, 1912, he saw one on Wilstone Reservoir ; on May 4, 1913, one with a party of the Yellow (Ray's) Wagtails at Startops End Reservoir ; and on May 3 and 10, 1914, a single one on Wilstone Reservoir. 41 (83). BRITISH TREE CREEPER. Certhia familiaris brittanica Ridgw. B. of Berks, and Bucks, p. 49. Viet. Hist, of Bucks, p. 133. Resident. Used not to be rare, but has greatly diminished in number since the severe winter of 1917. 42 (86). BRITISH NUTHATCH. Sitta europaea britannica Hart. B. of Berks, and Bucks, p. 50. Vict. Hist, of Bucks, p. 133. Resident. Not uncommon in well-timbered parts of the comity, particularly in Burnharn Beeches and Ashridge Park, but somewhat local and not very numerous any- where. 43 (88). BRITISH GREAT TIT. Parus major newtoni Prazak. B. of Berks, and Bucks, p. 23. Vict. Hist, of Bucks, p. 133. Resident. Generally the commonest of our Titmice. Though greatly reduced in 1917, increasing again rapidly in numbers. 44 (90). BRITISH BLUE TIT. Parus caeruleus obscurus Prazak. B. of Berks, and Bucks, p. 24. Vict. Hist, of Bucks, p. 133. Resident. Common, and apparently in many places scarcely less numerous than the ' Great Tit. 45 (92). BRITISH COAL-TIT. Parus ater britannicus Sharpe & Dress. B. of Berks, and Bucks, p. 24. Vict. Hist, of Bucks, p. 133. Resident. Fairly common in woods, parks, orchards, and gardens, especially where conifers are grown. Though the species suffered greatly during the severe cold of 1917, it is already increasing remarkably. Novitates Zoolooicae XXVII. 1920. 185 46 (97). BRITISH MARSH-TIT. Parus palustris dresseri Stejn. B. of Berks, and Bucks, p. 25. Vict. Hist, of Bucks, p. 133. Resident. Used to be fairly common, but has become much rarer since the severe frost of 1917. It is, however, increasing again in numbers. 47 (98). BRITISH WILLOW-TIT. Parus atricapillus kleinschmidti Hellm. The only record for Bucks of which we are aware is a male, formerly in the collection of H. H. Slater (now in the Tring Museum), shot by him at " Chersley, Bucks, 9.xi.l882.'' It was, of course, labelled by the collector as "Parus palustris," as at that time it was not yet distinguished, but is undoubtedly the present form. 48 (101). BRITISH LONG-TAILED TITMOUSE. Aegithalos caudatus roseus (Blyth). B. of Berks, and Bucks, p. 25. Vict. Hist, of Bucks, p. 133. Resident. Used to be found in practically all suitable localities, but suffered greatly during the severe frost of 1917. Near the Tring Reservoirs it bred year after year, but has been exterminated in that neighbourhood and not yet seen again. Prior to 1917 it used also to nest fairly commonly at Burnham Beeches, Ditton Park, etc., but has disappeared almost entirely from that district (E. E. Pettitt). As it is beginning to recover its former status in Berks., it will probably reappear in these localities before long. 49 (103). BRITISH GOLDCREST. Regulus regulus anglorum Hart. B. of Berks, and Bucks, p. 23. Vict. Hist, of Bucks, p. 132. Resident. Used to be fairly common in suitable localities, but has suffered greatly by the severe frost of 1917, and is now a rare bird. On July 28, 1918, Chas. Oldham heard one singing in the shrubbery at Aston Clinton Park, and another in the park at Ashridge on January 18, 1919 — the only two he has come across since the winter of 1916-17. Hartert has only seen a few near Tring, but not yet in Bucks., since 1917. In the south of the county it was formerly not uncommon, breeding in the Thames Valley at many points, but is only just beginning to reappear in small numbers. 50 (104). FIRECREST. Regulus ignicapillus ignicapillus (Temm.). B. of Berks, and Bucks, p. 173. Vict. Hist, of Bucks, p. 132. Exceptional winter visitor. Mr. Alfred Heneage Cocks informed us in 1902 of a specimen killed by his gardener, in his and his brother's presence, at Great Marlow in the sixties, about 1863. It was mounted and is in Mr. Cocks's possession, but it was only identified as a Fireerest some years after. According to Kennedy (I.e.), two Firecrests were procured near Eton about 1 865. This record is rather vague, and as soon after it is stated that a nest with 1S6 N0V1TATES ZOOLOGICAE XXVII. 1920. young, and the two parents, were brought to a Mr. Hasell in 1863, from Windsor Park, and the latter statement cannot be credited, the Eton record can hardly be accepted without caution. In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, it is stated that one was shot in January 1887, presumably at the Reservoirs. This statement, said to have been made on the authority of the then Hon. Walter Rothschild, is evidently erroneous, as all the supposed author remembers is a verbal statement made to him by the late Rev. H. H. Crewe that it had occurred in Ashridge Park. 51 (105). BEARDED TITMOUSE. Panurus biarmicus biarmicus (L.). B. of Berks, and Bucks, p. 174. Exceptional vagrant — one old record. On December 21, 1848, a pair, male and female, were shot on Wilstone Reservoir by the Rev. James Williams, of Tring Park. Only these two specimens were observed, and there is no other record of the occurrence of this species {Zoologist, 1849, p. 2418.) (About twenty years ago some specimens imported from Holland were released on Wilstone Reservoirs, but they disappeared.) 52 (107). GREAT GREY SHRDSE. Lanius excubitor excubitor L. B. of Berks, and Bucks, p. 168. Vict. Hist, of Backs, p. 134. Irregular and rare winter visitor. On January 8, 177S, one was shot near Dinton Hall. A female was shot near Wendover about the middle of November 1854, and a male on November 4 of the same year near Weston Turville (H. H. Crewe, Zoologist, 1865, p. 9416). In the winter of 1859-60 a specimen was shot on the banks of the Thames near Clewer, Berks. According to Kennedy (I.e.), a male was shot in 1862 near the Almshouses at Stoke, another in the winter 1865-66 on the banks of the Thames near Windsor, a third at Hampden (no date) which was in Bryant Burgess's collection. Mr. A. H. Cocks also reports one shot close to Great Marlow, either in the eighties or early in the nineties. Hartert saw one in October 1895 near Halton. A female was shot by the present Lord Rothschild on the " Flats " close to the Bucks, boundary near Cholesbury, 17.x. 1895; a male by a keeper near Long Marston, also close to the boundary, 1 8 . xi . 1 896 ; another female caught in a Sparrow-trap at Wilstone Reservoir, 2 . ii. 1 916. 53 (112). RED-BACKED SHRIKE. Lanius collurio collurio L. B. of Berks, and Bucks, p. 72. Vict. Hist, of Bucks, p. 134. Summer resident. Rather local and less common during the last twelve years or more than it used to be. In Kennedy's time it was common near Eton. Hubert D. Astley found it not rare near Chequers Court ; and Hartert has observed it there and near Wendover, Aston Clinton, Aylesbury, Buckingham, Dinton, Newport Pagnell, Castlethorpe, Wingrave, and Aston Abbots, but has not seen it recently near Wendover and Aston Clinton in places where it always used to be in evidence. Near the Reservoirs only about one pair has nested recentty. In the Thames Valley it is rather local, but Mr. Pettitt reports a few pairs breeding near Colne- brook, Horton, and Little Marlow. NOVTTATES ZOOLOOICAE XXVII. 1920. 187 54 (113). WAXWING. Bombycilla garralus (L.). B. of Berks, and Bucks, p. 174. Vict. Hist, of Bucks, p. 135. Irregular and rare winter visitor. Kennedy (I.e.) writes : " An immense flock appeared along the eastern shores of our island in the winter of 1849-50, which was very severe, and several speci- mens were at that time procured in different parishes of Buckinghamshire. I am indebted to the Rev. Bryant Burgess for the notice of a Bohemian Waxwing which was killed at Ivinghoe Aston in January 1850, and which is now in his collection. An immense number of Bohemian Waxwings were shot in the neigh- bourhood of Buckingham during the spring of 1867, as Mr. J. W. Thorpe told me." [In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, in a list of birds supposed to have occurred on the Reservoirs, it is stated that a Waxwing was " obtained in March 1883." Unfortunately this statement, made on the authority of the Hon. Walter Rothschild, cannot now be verified, as we cannot trace the specimen. In the Vict. Hist, of Herts, p. 201, it is said that " the first Hertfordshire specimen of the Waxwing was shot about a mile from Tring on the Aylesbury road, about 1851." As the Bucks boundary is very little more than a mile from Tring, this may almost be regarded as a Bucks record.] 55 (114). SPOTTED FLYCATCHER. Muscicapa striate striate (Pall.). B. of Berks, and Bucks, p. 74. Vicl. Hist, of Bucks, p. 135. Summer resident. Common everywhere in parks, large old gardens, and certain woods. The blue unspotted type of egg has been found near Slough (H. H. Vyse, Zool. 1890, p. 352, and Field, August 16, 1890, p. 250). 56 (116). PIED FLYCATCHER. Muscicapa hypoleuca hypoleuca (Pall.). B. of Berks, and Bucks, p. 169. Vict. Hist, of Bucks, p. 135. Probably occasional summer resident. The records for Bucks, are very few. According to Morris one was killed " many years ago " in the county, in the south-east, not far from Uxbridge. H. J. Elwes informed Kennedy of a well-authenticated nest taken near Eton in the summer of 1860. Mr. Heatley Noble, in litt. : "A nest with six eggs was taken on my late father's property, Berry Hill, Taplow, in June, 187- (the exact year cannot be given). The female was unfortunately killed on the nest." Mr. H. Heneage Cocks, in litt., says : " On May 12, 1883, our gardener at Great Marlow saw in our orchard a bird with white on the wings, which, from its move- ments and other habits, must have been a Flycatcher. He said it looked some- what like a female Chaffinch, but the beak was different. Sir J. A. Godley, K.C.B., reported several years before having seen one specimen there. Two days afterwards the gardener saw evidently the pair, but though I watched for them repeatedly I did not see them, nor were they ever seen again." On May 10, 1901, Hartert heard the song and observed a male in the park of Mentmore. In June of the same year he found no trace of these birds, nor ever afterwards. Mr. Edwin Hollis, while fishing at Hartwell, August 22, 1919, saw a male Pied Flycatcher. It was quite clearly recognized, as it sat within 8 or 10 feet of the observer for several minutes. 188 NOVITATES ZOOLOGKAE XXVII. 1020. 57 (119). CHIPFCHAFF. Phylloscopus collybita collybita (Vieill.). B. of Berks, and Bucks, p. 85. Vict. Hist, of Bucks, p. 132. Summer resident and autumn migrant. Common in all suitable localities. From February 10 to 18 a Chiffchaff frequented some willows on Wilstone Reservoir. (See Brit. B. vol. vi. p. 313.) In the Thames Valley it is generally distributed, and Mr. Pettitt notes it as especially numerous in Ditton Park. 58 (122). WILLOW- WARBLER. Phylloscopus trochilus trocbilus (L.). B. of Berks, and Bucks, p. 84. Vict. Hist, of Bucks, p. 132. Summer resident ami passage migrant. Generally distributed and hardly absent from any suitable localities. 59 (125). WOOD- WREN or WOOD- WARBLER. Phylloscopus sibilate sibilatrix (Bechst.). B. of Berks, and Bucks, p. 84. Vict. Hist, of Bucks, p. 132. Summer resident. The Wood-Wren occurs from April to September in beech and oak woods, in the Chilterns and near Brickhill. In the Thames Valley it is decidedly scarce and entirely absent from the greater part of the district. Mr. Grossman, however, states that it was formerly fairly plentiful in Burnham Beeches and in the woods between that place and Ashley Green ; but Mr. Pettitt has failed to meet with it breeding. A few pairs, however, haunt the woods near the western boundary where the county is more hilly. [SAVI'S WARBLER. Locustella luscinioides luscinioides (Savi). B. of Berks, and Bucks p. 172. In the Zoologist, 1867, p. 704, Lord Clifton published a note saying that he believed that he had observed a Savi's Warbler in a low hedge near Eton, but his description of the bird he saw is by no means convincing ; in fact the statement cannot be accepted. As is well known, the species was formerly a summer resident in Norfolk, Cambridgeshire, and Huntingdon, but, except for a single bird obtained on Fair Isle (!) in 1908, has not been proved to occur since 1856. Another rather vague record appeared in Saunders' Manual Brit. B. ed. ii. p. 92 (1899), as follows : " There is some evidence that this species was noticed in May 1897, in the Humber district, as well as near Olney, Bucks. ' : The latter statement refers to an observation by Mr. C. J. Wilson, M.B.O.U., who kindly wrote to Hartert that he is fully convinced that the " Savi's Warbler is a just record," because he was close to the bird for some minutes, and the locality, the appearance, and the note of the bird were all in favour of its being L. luscinioides.] 60 (133). GRASSHOPPER- WARBLER. Locustella naevia naevia (Bodd.). B. of Berks and Bucks p. 78. Vict. Hist, of Bucks, p. 132. Summer resident. Rather rare. The only certain localities we know of are : on the foot of the hills east of Halton (heard and seen by Arthur Goodson and Ernst Hartert), NOTITATES ZOOLOGICAE XXVII. 1920. 189 Aylesbury (eggs seen by Hartert), Mentmore (heard by Hartert), Castlethorpe (observed by the late Lionel Wiglesworth), Farnham Common (observed by Alan Crossman), Chesham and High Wycombe (teste Kennedy), Drayton Beauchamp (Kennedy, probably from information of Harpur Crewe). In the Thames Valley it is a rare visitor, but Mr. E. E. Pettitt discovered a nest with five eggs at Hythe End in May 1894. Breeding also took place there in 1904, as well as at Wrays- bury in 1919. Mr. Pettitt notes the arrival of this species in the county on April 22, 1895, April 19, 1900, April 21, 1905, and April 30, 1910. In 1919 a pair nested close to Marsworth Reservoir, and the nest was found by Mrs. Oliver Pike, and some beautiful photographs taken by her busband. Mr. Pike is convinced that there were two pairs, but only one nest was found. The Grasshopper- Warbler had not occurred in this place during the last twenty-five years or more. 61 (136). REED-WARBLER. Acrocephalus scirpaceus scirpaceus (Herm.). B. of Berks, and Bucks, p. 80. Vict. Hist, of Bucks, p. 132. Summer- resident. Very common on the Marsworth, Wilstone, and Halton (Weston Turville) Reservoirs, and also on the Rivers Thames, Colne, Chess, and Ouse, wherever reeds abound. On the Tring Reservoir the Reed- Warbler is the usual and apparently only foster-parent of the Cuckoo, and all Cuckoo's eggs found there for the last twenty-five years are of much the same type, of course with some variations. Along the Thames and Colne Valleys it breeds commonly, as well as on the pond at Burnham Beeches. Mr. Pettitt has on two occasions found two Cuckoo's eggs in a Reed- War bier's nest in Bucks. For a note on unusually early nesting of this species at the Tring Reservoirs, see Brit. Birds (mag.), vol. ix. p. 48. 62 (137). MARSH- WARBLER. Acrocephalus palustris (Bechst.). Bred in 1909. (In Trans. Herts. Nat. Hist. Soc. vol. v. p. 76, it was stated, on the authority of the Hon. Walter Rothschild, that a Marsh-Warbler was shot near the Mars- worth Reservoir in August 1883, and was in the Tring Park collection. This statement seems to be due to an error in identification of a young Reed- Warbler.) At the time of the publication of the Vict. Hist, of Bucks, this species had not been ascertained to breed in the county. In 19C9 Mr. G. W. Kerr, who had previously discovered the Marsh- Warbler breeding in Surrey, was fortunate in discovering a nest with two eggs of this species, and also one of the Cuckoo in a dense nettle- bed not far from Magna Charta Island on June 1 4. The nest was about 12 yards from the river on firm ground, woven round two nettle stems, and about 18 in. from the ground in the parish of Wraysbury. (The locality in Surrey where the nest was foimd in 1907 is only a few miles south of the county boundary, and about five miles distant from where the birds were found breeding in 1909.) Subsequently Mr. E. E. Pettitt found a second nest at Wraysbury in the same nettle- bed, containing four Marsh- Warbler's eggs and one of the Cuckoo, on June 30, 1909, but the Cuckoo's egg was of a different type to that found on June 14 (Zool. 1909, p. 397). 190 NOV1TATES ZOOLOGICAE XXVII. 1920. 63 (139). SEDGE-WARBLER. Acrocephalus schoenobaenus (L.). B. of Berks, and Bucks, p. 78. Vict. Hist, of Bucks, p. 132. Summer resident. The Sedge-Warbler is generally distributed in the valleys, in the neighbour- hood of rivers, ditches, reservoirs and ponds, sometimes in thickly over-grown hedgerows quite a distance from water. Yarrell states that a single specimen was observed near High W^conibe in winter, without giving full date. Such a state- ment is hardly acceptable without proof, but curiously enough there are other statements of the occurrence of Sedge- Warblers in winter. 64 (145). GARDEN- WARBLER. Sylvia borin (Bodd.). B. of Berks, and Bucks, p. 82. Vict. Hist, of Bucks, p. 131. Summer resident. In similar places to the Blackcap, but far less common. Grossman and Hartert have observed it near Chesham, Beaconsfield, Burnham Beeches, Halton, Aylesbury, Buckingham, Mentmore, Ashridge Park, Castlethorpe, and Newport Pagnell ; but it occurs doubtless in many other places. In the Thames Valley it breeds in suitable spots, but in far smaller numbers than the Blackcap. Mr. E. E. Pettitt found a nest in Ditton Park which contained a young Cuckoo about four days old on June 5, 1906. 65 (146). BLACKCAP. Sylvia atricapilla atricapilla (L.). B. of Berks and Bucks, p. 82. Vict. Hist, of Bucks, p. 131. Summer resident. Common in parks, woods with undergrowth, gardens and spinneys. Gener- ally arrives end or middle of April, but Hartert. has heard it in full song on April 10, near Wilstone Reservoir. 66 (147). WHITETHROAT. Sylvia communis communis Lath. B. of Berks, and Bucks, p. 83. Vict. Hist, of Bucks, p. 131. Summer resident. Common in suitable localities, such as hedgerows, commons, edges of woods, and some gardens. 67 (148). LESSER WHITETHROAT. Sylvia curruca curruca (L.). B. of Berks and Bucks, p. 83. Vict. Hist, of Bucks, p. 131. Summer resident. The Lesser Whitethroat is generally less numerous than the Whitethroat, but not a rare bird. It is curious that it should be so much more plentiful in Middlesex than in the adjoining parts of Bucks. 68 (155). FIELDFARE. Turdus pilaris L. B. of Berks, and Bucks, p. 105. Vict. Hist, of Bucks, p. 130. Winter visitor. Arrives usually in October or even November, but there are records by Lord Rothschild and others for September ; getting scarcer from end of March, and Novitates Zoolooicae XXVII. 1920. 191 usually leaving before the end of April, but Crossman mentions ( Vict. Hist. Herts. p. 196) some seen at Great Gaddesden, on the boundary of Herts, and Bucks., on May 8, 1887. 69 (156). MISTLE-THRUSH. Turdus viscivorus viscivorus L. B. of Berks, and Bucks, p. 12. Vict. Hist, of Bucks, p. 129. Resident. Common in woods and parks over the greater part of the county, but not in any great numbers in the Thames Valley. 70 (157). BRITISH SONG-THRUSH. Turdus philomelos clarkei Hart. B. of Berks, and Bucks, p. 13. Vict. Hist, of Bucks, p. 129. Common resident. The British Song-Thrush is even more numerous than the Blackbird, and stays in Bucks, throughout the year, but a fair number pass through in the autumn, and some in the spring, evidently from higher ground in the north of England and Scotland. We have not been able to detect a specimen of the Continental Song- Thrush among them. The number of Song-Thrushes diminished very greatly in the severe winter of 1917, and though they have increased again considerably in numbers, they are still far behind their strength of before 1917. In the Newton collection at Cambridge is a clutch of four eggs of this species, taken near Stoke in May 1861, in which the ground-colour is perfectly white, with the usual markings. They were at first recorded as eggs of the Golden Oriole. See Ootheca Wolleyana, vol. ii. p. 288, and Field, May 25, 1861, p. 451. 71 (159). REDWING. Turdus musicus L. 1758. [Turdus iliacus L. 1766, of most authors.] B. of Berks, and Bucks, p. 106. Vict. Hist, of Bucks, vol. i. p. 130. Common winter visitor. Generally arriving about the middle of October and leaving towards end of March. Mr. Heneage Cocks formerly reported a specimen shot at Harleyford on July 28, 1871, and Mr. E. Burton Durham records one picked up in September 1913 at Chesham Bois (Field, September 27, 1913). On March 11, 1906, Mr. A. H. Cocks met with an enormous flock of this species resting in some meadows near Skirmett. The birds were thickly distri- buted over eight acres of grass land, so that allowing for one bird to each square yard, there must have been over 38,000 birds present ! In the cold winter of 1917 all or nearly all Redwings which were in the county at that time perished ; but in the following winter, though scarcer than usual, more Redwings were seen than Fieldfares. The cold winter of 1854, according to the Field, also destroyed Redwings and Fieldfares " by tens of thousands." In 1918 Redwings were generally very scarce. Hartert saw none until March, when he came to a place — a shrubbery of evergreens — where hundreds were roosting. In 1919 they were probably about as common as before the severe frost, and hundreds came to roost in the same place as the winter before, at least from January to March. 192 Novitates Zoolooicae XXVII. 1920. 72 (162). RING-OUZEL. Turdus torquatus torquatus L. B. of Berks, and Bucks, p. 136. Vict. Hist, of Bucks, p. 130. Passage migrant. Kennedy (I.e.) mentions a specimen shot at Risborough " in the spring " of 1840, and another observed by Burgess in his garden at Latimer, September 9, 1862. when specimens were also seen near Dundridge and Wendover. In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, specimens supposed to have been killed in July 1886, and in October of the same year, are mentioned. The former statement is probably incorrect, being from hearsay or recollection. In 1865 a male was killed near Burnham, and the Rev. H. H. Crewe observed specimens near Drayton Beauchamp, both in spring and autumn. Mr. A. H. Cocks informed Hartert, in lift., that one was shot near Chequers Court about 1878, and another at Stoke Mandeville " at least as long ago as 18S7." The Rev. Hubert Astley has several times observed Ring-Ouzels amongst the juniper bushes near Wendover and Chequers Court. In the Tring Museum is a (J shot at Wingrave 4 . xi . 1896, while others have been observed in autumn, and two shot near Tring, September 14, 1893. Mr. E. E. Pettitt saw one on the Middlesex border, near Stanwell Moor, on April 1, 1907 (in Hit.). 73 (164). BLA
