SUPPLEMENT TO THE GAME ANIMALS OF AFRICA SUPECE MENT “ko Tice ANE ANIMALS OF ABRIG2 IN the following pages I have endeavoured to bring the volume as nearly as possible up to date. Most of the matter in the “ Addenda G issued with the volume has been incorporated, and the loose sheet relating to Foa’s zebra has likewise been included. R. LYDEKKER. HARPENDEN, November 1911. THE AFRICAN ELEPHANT (Page 1) It is stated by Mr. F. A. Knowles in the Journal of the East Africa and Uganda Natural History Society for 1911, vol. ii. No. 3, p. 21, that an elephant, locally known as the forest-elephant, and distinguished by its very long and slender tusks, is an occasional visitor to Uganda from the Semliki and the district west of the Albert Nyanza. This elephant is evidently Evephas africanus albertensts (supra, p. 8), described by myself on the evidence of a tuskless skull, and may now be known as the Semliki race. A pair of tusks from the Semliki received by Mr. Rowland Ward in 1911 were of the slender type described by Mr. Knowles. The Unyoro elephant, which has been provisionally associated by myself with the Semliki race, is stated by Mr. Knowles to be perfectly distinct, and therefore seems to require a new name. 1 a iS) S UPPLEMENT THE BEACK “RHINOCEROS (Page 25) In a paper published in the Proceedings of the Zoological Society of London for 1909 (p. 198) Dr. E. L. Trouessart suggested that the type of horn described as Rhznoceros holimwoodi is referable to the northern race of the white rhinoceros (2X. seus cottont). In the Freld for 1909 (vol. civ. p. 193) I have, however, given reasons in support of the opinion that the long and slender East African horns of the holmwoodt type are referable to a local form of the black rhinoceros ; and since the publication of that notice I have obtained additional evidence in favour of the same view. The typical specimen was purchased at Zanzibar, but in a pair from British East Africa, presented by Dr. Ansorge to the British Museum, the front horn has the same general character, thereby indicating that this district is the habitat of R. d¢cornis holmwoodt. In Count Joseph Potocki’s Sport zx Somaliland (1900, p. 82) the name somaliensis was applied to the Somali rhinoceros, and although no diagnosis was given, the fact that the name is accompanied by a plate of the animal entitles it to recognition. That the Somali rhinoceros should rank as a local race (R. bzcornzts somaliensis) has been demonstrated by myself in the Proceedings of the Zoological Society for 1911, p. 958, where it is shown that the skull, in comparison with an East African specimen, is distinguished—in addition to its inferior size—by its relatively narrow form. THE BONTE-QUAGGA (Page 50) Specimens collected in 1910 by Messrs. Selous and McMillan show that the bonte-quagga, or zebra, inhabiting the Guasengishu plateau of East Africa is more or less completely maneless, lacking even the fore-lock. This gives a very remarkable appearance, the ears standing out from the head like horns instead of being connected by means of the mane and fore-lock. These Guasengishu bonte-quaggas cannot, however, be regarded as even racially distinct from Hguus burchellt granti, since some examples from the Athi plains—the typical locality ‘of that race—have the mane much less developed than in other representatives of the species. BONTE-QUAGGA 3 In 1911, Mr. R. B. Woosnam, Game Warden of the East African Protectorate, sent home a photograph of the skin of a Grant’s bonte- quagga in which a saddle-shaped patch on the hind part of the back is devoid of stripes. This unstriped area is situated just where the longitudinal stripes of the hind-quarters pass into the transverse stripes of the back, and occupies about half the interval between that point and the withers. The dorsal stripes are continued through it, and below it the belly-stripes have the normal development. In colour the pale unstriped area is dirty white. The animal, which is adult, was killed near Nakuru, and a few days later a second, but half-grown individual with a similar uniformly coloured area, was shot in the same place. Mr. Woosnam states that the natives are well acquainted with such abnormally coloured zebras, of which for many years there have been one or two among the herds, but never more. In JVature, vol. Ixxxvi. p. 241, 1901, Professor Ridgeway proposed the name &. burchelli goldfincht for these zebras which are, however, nothing more than abnormalities. On page 97 of vol. xxiii. of the AZemozrs of the Linnean Society of Normandy, 1910, Messrs. Brasil and Pennetier described a bonte- quagga as F. burchelli pocockt. The specimen on which this determina- tion is based is a stallion in the natural history museum at Rouen, obtained in 1882 from the menagerie of one Pézon. Nothing is known of its previous history, although from the type of marking it may be considered certain that it came from southern Africa. In the almost complete absence of barring on the limbs it agrees with the typical £. burchellz, but the shoulders and quarters are completely striped, and the body-stripes are continued downwards to join the longitudinal ventral stripe. In the latter respect the race resembles the Zulu £. 0. wahlberg?, in which the legs are barred to some distance below the knees and hocks. The ground-colour of the coat is cream instead of white, as in the typical durchellc. Its describers consider that £. 0, pococki is extinct, and to a considerable extent intermediate between E. b. typicus on the one hand and E&. 0. chapmani and E. 6. wahlbergi on the other. In the Fze/d for 1909, vol. cxiv. p. 889, Mr. Pocock has given reasons for considering the so-called Ward’s zebra (supra, p. 65) as a hybrid, born in Messrs. Barnum and Bailie’s Menagerie, between the typical zebra and Chapman’s bonte-quagga. This so-called species, to which Professor Ridgway inadvertently gave the technical name of £. wardt in the Proceedings of the Zoological Society for 1909, p. 798, must accordingly disappear. b 4 SUOPPLEMENT The South Abyssinian bonte-quagga has been separated by Mr. Camerano (A/ti Ac. Reale Torino, 1902, p. 10) from the Masai Eguus burchelli granti as E. 0. jalle. The zebra from North-east Rhodesia described as /. annectans (supra, p. 65) is regarded by Mr. R. I. Pocock (“ Harmsworth Natural History,” p. 789) as a bonte-quagga nearly allied to &. 0. crawshay, and specially characterised by the great width of the black stripes. BOA'S ZEBRA (Equus foaz) To the zebra inhabiting the mountainous country opposite Teti, on the north bank of the lower part of the Zambesi, Messrs. Prazak and Trouessart in 1899 (Bulletin Muséum ad Histoire Naturelle, Paris, vol. v. p. 350) gave the name Eguuzs foat. From all races of the bonte- quagga this zebra is distinguished by the larger number of main stripes on the body and hind-quarters, and by the circumstance that there is no backward bending (except in the last of the series) of the body- stripes as they approach the dorsal stripe, to which they run approximately at right angles. In this respect Foa’s zebra approxi- mates to the true zebra and Grévy’s zebra, from both of which it differs by the stripes on the hind-quarters adjacent to the dorsal stripe running parallel with the latter in the direction of the tail, as in the bonte-quagga, instead of at right angles. Consequently, the “ gridiron ” pattern of zebra and the concentric stripe-arrangement of gvevy7 in this region are alike wanting. In general build, as well as in the shape of the head and ears, Foa’s zebra is nearer to the bonte-quagga than to either of the other species; this being borne out by the fact that the body-stripes meet the stripe traversing the middle line of the under surface. The legs are striped to the fetlocks, and the pasterns black. This species is probably related to Crawshay’s bonte- quagga. THE AFRICAN BUFFALO (Page 67) In the Proceedings of the Zoological Society for 1910, p. 993, I described a small buffalo from the left bank of the Kwilu river, in BUFFALO 5 Belgian Congo, as Bos caffer scmpsoni. In their heavily fringed ears and the general form of the horns these buffaloes approximate te the small red B. c. xanus, but the horns are larger, the right one of a bull measuring 252 inches along the outer curve and the left one 24% inches; the basal girth of the former being 164 inches, its maximum width 62 inches, and the expanse from tip to tip 13g inches. In a cow the left horn measured 15 inches in length, with a girth of 94, and an expanse of 82 inches. In profile the horns incline upwards nearly in the plane of the face. The colour of cows and bulls is pure brown, much darker than the tawny red of xanws—the young only agreeing approximately in hue with the latter, and the cows being fully as dark as bulls. Usually the fringes of the ears are tinged with tawny, with one white lock. In the same paper a pair of horns brought home by Dr. K. W. Kumm from the upper Shari valley, in the Lake Chad district, is provisionally referred to B. c. thzerryz, a race typically from Togoland, German West Africa. The Shari horns are deeper in the antero-posterior direction at their bases, where they are more expanded and flattened, and also more closely approximated in the middle line than in the type of thierryz; but since the latter is a female there seems no reason why they should not pertain to the same race. The above paper also contains a note on two heads of red buffaloes from French Congo, which appear inseparable from JS. ¢. cottonz of the Semliki. Another, but at present unnamed race of dwarf buffalo inhabits the Yala district of southern Nigeria, and is characterised by the bulls being brownish black and the cows dun or khaki-coloured. Bulls stand from 34 to 4 ft. at the withers, and are short-legged and heavily built animals. In the adults of both sexes the legs are light- coloured from the knees and hocks to the hoofs. Calves are dark orey. Specimens of the Senegambian B. c. planzceros brought from the Gambia by Mr. Russell Roberts in 1910 show that this race is con- siderably larger than B. c. zanus, with the horns more laterally expanded and recurved, and the general colour brown. It may be added that in the Proceedings of the Biological Society of Washington for 1911, vol. xxiv. p. 191, Mr. N. Hollister expresses the opinion that as the African buffalo is so distinct from the Indian species it ought not to be included in Awbalus ; if this view be accepted, the name Syucerus is available as a subgeneric title. 6 SOPPLE MENT: THE LELWEL HARTEBEES® (Page 107) The statement that the typical race of this species, which was described by Heuglin on the evidence of a horn probably bought from Sudani traders, has a dark face-blaze is incorrect. A male and female believed to be from the Lado district were uniformly reddish. tawny, with the tips of the horns inclining inwards. THE. KORRIGUM, TIANG, “OR Ort (Page 116) A topi from the Guasengishu plateau of British East Africa, lying to the eastward of Mount Elgon, is distinguished from Damadlzescus corriguim grmela by the blaze on the face being whitish buff, or white instead of black. Although described by Prof. A. Cabrera on page 998 of the Proceedings of the Zoological Society for 1910 as a species, it may be regarded as a local race under the name of D. c. phalus. In old bulls the blaze is stated to be as white as in a blesbok. THE BRINDLED GNU OR BLUE WILDEBEEST (Page 134) The typical form of the white-bearded race from Kilimanjaro is tawny-coloured, with the fore-quarters marked by transverse chocolate- coloured bands, and the greater portion of the front of the face as well as the sides of the lower part, together with the ears, nearly black. On the other hand, a dark phase is exemplified by a skin from the south of Lake Naivasha, British East Africa, presented to'the British Museum by Mr. H. H. Tarn in 1907, by others from the Guaso Nyero valley given by Mr. R. J. Cuninghame in 1908, and by others from East Africa presented by the Master of Belhaven; in these the general colour of the coat of the neck, fore-quarters, and flanks is more or less uniformly blackish brown, passing into dark tawny on a larger or smaller area on the upper surface of the hind-quarters, this light area, which is traversed anteriorly by a dark stripe, extending in one DUIKERBOK ji specimen as far as the mane, but in other examples being mainly confined to the rump. In one skin there is distinct brindling on the neck, but elsewhere both dark and light areas are almost free from bands, although a few indistinct bars occur on the sides of the chest in one skin. Other specimens show a gradual increase in the number and distinctness of the barrings, accompanied by a lightening of the colour of the coat, so that there seems to be practically a transition to the light-coloured and brindled Kilimanjaro gnu. tiie DUIKER BOK (Page 141) The more typical long-eared representatives of the species are found all over South Africa; the most northern form of these on the west being Cephalophus grimme splendidulus, Gray, from Angola ; farther east is the Matabili C. g. flavescens, Lorenz, which probably crosses the Zambesi into northern Rhodesia ; the eastern representative is C. g. altifrons, Peters (=ocularzs, Pet.) from southern Mozambique, which ranges south of the Zambesi to Tette and north to the Loangwa river, at least as far south as Angoniland. In the Shiré Highlands Mr. R. C. Wroughton has shown (Annals and Magazine of Natural History for 1910, series 8, vol. v. page 274,) that these long-eared races give place to short-eared types allied to the Abyssinian duikerbok, which is often reckoned as a species, but which may be regarded as a race of the southern one, under the name of C. g. abyssinicus. The Shiré race, which on this view will be known as C. g. shzrenszs, agrees in size with the other East African forms, but is distinguished by its brighter ochery coat, the general colour above being ochery buff; all the hairs have drab bases, those of the neck and shoulders are ochery buff to their tips, those of the back shortly tipped with black. Below the colour is the same as in the next race, but much paler. The second race described by Mr. Wroughton, C. g. Azndez, is from Nyasaland and characterised by its bright colouring. In size it is about the same as C. g. myansae; its general colour above being tawny ochre, bright on the neck and shoulders, duller on the back and loins, but the yellow tinge is never absent, even on the rump, as it is in nyansae ; individual hairs of the neck are drab-grey, with ochery tips, but posteriorly the ochery tip becomes a sub-apical ring and the tip black. The chin and insides of the upper part of the limbs are c 8 SOPPLEMENT whitish; the throat ochery buff, with the hairs the same colour throughout, but on the flanks the hairs are coloured like the neck although with drab bases. The grizzling characteristic of the more northern forms in C. g. skzrenszs is so fine and faint that, at a short distance, the coat seems to be uniformly coloured—this and the pale bright ochery colouring serving to distinguish this race from all the rest. NYASA BLEUE SDUIKER (Page 164) The Congo representative of this species has been described by Dr. E. Loénnberg (Arkiv for Zoologz, vol. iv. No. 16, p. 12, 1908) as Cephalophus nyasae congicus. It is distinguished from the typical race by colour. In the latter the back is described as being of a darker brown than in montecola, with a more distinct rufous suffusion, while the rump is dark chocolate-brown. In the Congo race the back is warm sepia, of nearly the same tint from neck to rump. Towards the flanks this shades off into light smoky grey, with a slight buffy tinge, due to the tips of the hairs being of that colour, while the under surface is white. On the hams the hairs are sufficiently rufous at the tips to communicate a tinge of this colour, although the rest of the hairs are of the same grey as the flanks. The rufous tinge of the hams is sharply defined from the dark sepia-brown of the rump, but shades into that of the back. The legs are rufous, with a smoky brown mark above the sides of the hoofs; the face is nearly black, with a dull rufous brown stripe; and the tail is black above and white beneath. The skull of both races of xyasae differs from that of sondzecola by the great relative length and narrowness of the muzzle. THE RED DUIRER In the Annals and Magazine of Natural History for 1911 (ser. 8, vol. viii. p. 278) Mr. R. C. Wroughton recognises four races of this species, two of which are named for the first time. Of these the Transvaal Cephalophus natalensis amaenus is distinguished by its richer colouring, which is redder on the back and yellower on the flanks, with the nape nearly black, whereas in the typical race the upper-parts KLIPSPRINGER 9 are tawny and the nape slatey grey. The so-called C. roberts? of Mozambique (p. 153 of the text), with which, as I have suggested, C. n. vasset is identical, forms the third race (C. 2. roberts?), distinguished by its larger size, paler colouring, and larger ears; the general colour being tawny ochre, with the under-parts paler. Lastly, the Nyasa C. n. bradshaw?, while agreeing in size with the preceding, differs by the still greater paleness of the colouring, the under-parts being dirty white. THE KEDPSPRINGIE (Page 166) The Masai race of this species (Oreotragus saltator schillingst) is distinguished by the general presence of horns in the female. In 1911 Capt. W. H. Wilkin forwarded to the British Museum the skin and skull of an immature horned female of this race killed by himself the preceding September on the Anala river, in British East Africa, about twelve miles from the German boundary (about 1°45’S. x 35° E.). Capt. Wilkin, who also shot a second and older female, states that on the Anala all the female klipspringers appeared to have horns, so that he gave up shooting them on account of his inability to distinguish bucks from does. On the other hand, he states that a sporting friend shot a female klipspringer near the junction of the Guaso Nyero and the Guaso Narok which was hornless. This, however, was not improb- ably an individual variation, as the locality is too near the centre of the range of schillingst to make it likely that a second race should occur there, and it is only reasonable to suppose that some females of that race may be destitute of horns. Our knowledge of the range of the klipspringer was extended in 1911 by the discovery that the species inhabits the mountains of Northern Nigeria. The first information on this point was afforded by Dr. Porteus, who presented the skull of a buck to the British Museum ; but this was supplemented by a letter from Mr. M. Hyatt, in which it was stated that the writer had killed three specimens in the Naraguta district. I have named the Nigerian race O. a. porteuse (Proc. Zool, Soc. 1911, p. 960). The skull is characterised by its -great width. According to information supplied by Mr. E. A. Hamilton klipspringers inhabit the mountains of Angola. 10 SOPPLEMENT THE GUASENGISHU ORIBI (Orbea microdon) The skull of a male oribi from the Guasengishu plateau of British East Africa is described by Mr. N. Hollister (Sazzthsonzan Mescell. Collections, vol. lvi. No. 2, p. 4, 1910) under the above name. It indicates a large species characterised by the relatively small size of the cheek-teeth, which occupy a smaller space than those of species with absolutely smaller skulls. A skull from the Lake Region which came under my own notice in IgiI presented a similar feature ; its horns measured 5% inches in length, or rather more than in the type specimen. LANG’S DIK-DIK (Madoqua langt) This species, which was named by Dr. J. A. Allen in the Bulletin of the American Museum of Natural History for 1909 (vol. xxvi. p. 153), is described as being indistinguishable in the colouring of the upper-parts from Kirk’s dik-dik (supra, p. 192), but with the lower surface pale fawn instead of clear white in front and dirty white behind, while the cheeks and the sides of the neck are tawny instead of yellowish grey, and the crown of the head is more strongly varied with yellowish rufous. The two species are, however, best distinguished by the characters of the skull ; that of M7. /angz being much the larger of the two, with bigger teeth, relatively as well as absolutely. The lower line of the muzzle of the skull is straight instead of arched, as in #zrkz, and the nasal bones are nearly three times as large as those of the latter, thus leading to the elongation of the fore-part of the skull generally. The type specimen was obtained at Elmenteita, British East Africa, at no great distance from the habitat of MW. cavendisht. Although the type of the latter indicates an immature individual, yet the skull is much larger than that of the present species, while the skin is differently coloured, being dark fawn above in place of yellowish grey. THE BEIRA (Page 278) Mr. Pocock (Proc. Zool. Soc., 1910, p. 878) regards the beira as related to the dik-diks, and not to the gazelles. ee — To face page 10 of Supplement. OTHER DIK-DIKS In the Aun. Mag. Nat. Hist. for 1909 (ser. 8, vol. iv. p. 49) Dr. Drake-Brockman described a new race of Phillips’s dik-dik from the Guban district of Somaliland, as Madogua phillipse gubanensts, and a new species from Abyssinia as JZ. cordeauxt. The former differs from the typical representative of the species by its thinner and shorter hairs, which give to the coat a sleeker appearance. The Harar dik- dik (supra, p. 190) is relegated by Dr. Brockman (Proc. Zool. Soc. IQII, p. 979) to a race of phzllps¢ characterised by its darker colour and thicker coat; it inhabits high ground. The name MW. placentinii has been given by the same writer (Proc. Zool. Soc. 1911, p. 981) toa Somali dik-dik allied to szayzez, but distinguished by the much greater development of the grizzling of the hairs, so that the whole of the upper-parts, with the exception of a clay-red nose-patch and the crest, appears grey ; the buff ears have black margins. Cordeaux’s dik-dik, on page 983 of the journal last cited, is referred by its describer to Rhynchotragus. Having the distinctive head-characters of that group, it much resembles JZ. phillips? gubanensis in general appearance, but is considerably larger. Yet another local race, 7. [X.] guenthert wroughtonz, from the north bank of the Wabi River, in the foot-hills of Mt. Abu-el-Kassim—far away from the typical locality of the species—has been described by Dr. Brockman (Anzu. Mag. Nat. Htst. op. cit. p. 51). It is specially distinguished by its larger ears and darker colour. Lastly, JZ. erlanger? Gupra, p: 190)-is: referred by Dr. Brockman (@.Z.S: TOr1, p. 633)to Rhynchotragus. WATERBEOCK TI THE WATERBUCK (Page 194) In a paper on the waterbucks in the collection of Major Powell- Cotton at Quex Park, Birchington, Dr. Paul Matschie (Sz¢z.-Ber. Ges. naturf. Freunde, Berlin, 1910, p. 409) describes two new races of the typical species. The first of these, Codus ellipsiprymnus pallidus (p. 410), is from the Webbe Shebeyli, Somaliland, and is distinguished from the typical race of the species by the general colour being very light brown, without any tendency to rufous, instead of a mixture of grey and russet brown. The white rings round the eyes are also much narrower; and the hair on the forehead and nasal region is a mixture of pale and sepia brown instead of dark brown. The strong curvature of the horns is likewise a distinctive feature. In the second race, C. e. thzkae (p. 411), from the Thika valley, N.E. of Nairobi, the forehead is burnt umber, the nasal region blackish grey-brown, the white band above the muzzle very narrow, and the light rings round the eyes of medium width, with brown hairs amid the white. The sides of the face are bright brownish grey mingled with sepia; the white of the chin ascends as high as the gape of the mouth. The throat and chest are warm sepia or russet mingled with grey; all the hairs being grey with rufous sepia tips; and there is a large white patch in the centre of the chest. The back is reddish sepia, and the flanks are but slightly tinged with grey. Above the hoofs is a white band about an inch in depth, broken by a narrow interval behind; and while the upper surface of the tail is coloured like the back, the under side is white. In the Lorian Swamp and the neighbouring part of the Guaso Nyiro valley, British East Africa, are found light-coloured or semi- albino waterbucks, with eyes of the normal hue. They are referred to by Col. W. H. Brown in the Proceedings of the Zoological Society for 1905, p. 297, and by Lord Gifford in the Fze/d of August 10, IgIO. The light individuals generally go about with normally-coloured waterbuck. THE DEFASSA WATERBUCK (Page 199) In the paper cited under the heading of the preceding species Dr. Matschie has named and described eleven local races of the i SUPPLEMENT defassa, based on the specimens in the collection of Major Powell- Cotton. These are Cobus defassa hawashensis, Hawash river, p. 413 ; d. powelli, Laikipia, p. 415; a@. angusticeps, do. p. 416; ad. nzotae, Guasengishu, p. 417; a. fulvifrons, e. of Kitosh, p. 418; a. avel- lanifrons, Lake Albert district, p. 419 ; cottonz, do. ,p. 420; dzanae, do., p. 421; a. breviceps, Pembe on the Nile, p. 424; d. ladoensts, Lado ‘district, p. 426; d. eréscotncius, no of Lado; p. 427. 9) Phew main points of difference are based on colour. VAUGHAN'S (KOB (Page 206) From observations made by Mr. Selous in the Bahr-el-Ghazal (see the /7ze/d, September 2nd and goth, 1911) it appears that Vaughan’s kob is restricted to the east central, central, and northern districts of that province, and that in summer it turns blackish. On the other hand, the kob of the south and south-western districts is a yellow-eared animal apparently related to the Uganda race of Buffon’s kob. The observations, supplemented by heads in the dark dress brought home by Mr. Selous, indicate that Vaughan’s kob is merely a local race of the white-eared species. For the present I do not propose so to name it, since, as I have suggested in the text, all the above forms may prove to be local races of Buffon’s kob. ROBBER (DS: 4eeGnwa Cobus robertsi On page 222 of the text this lechwi was stated to have been founded on immature specimens of C. smzthemant. Mr. Rothschild, who owns the type specimen, informs me, however, that this is not the case. C. roberts? appears, indeed, to come closer to C. /eche than to C. smithemant ; and is found in company with the former, from which it differs by the black patches on the sides of the lower part of the neck and part of the shoulders, as well as by the admixture of black on the cheeks and the sides of the throat and neck. The horns are also stouter, with the ridges closer together and wider. This species is a native of northern Rhodesia. GAZELLES 13 FLAY S- GAZELLE (Gazella hayz) Native name, Rhazalrim This species was named by myself in 1911 (Proc. Zool. Soc., p. 961) on the evidence of a mounted specimen in the British Museum, killed by Mr. M. V. Hay in Algeria, between Constantine and Biskra. Of the size of the dorcas, it is distinguished from that species by the absence of a distinct lyrate curvature to the horns, which carry only about twelve rings in place of twenty-four or twenty-five. The face-markings approximate to those of the edmi, the middle stripe being darker than in the dorcas, with a distinct nose-spot ; the eye-stripes are less conspicuous, and the forehead is not chestnut. There is no faint light stripe above the flank-band ; the knee-tufts are larger and blacker than in the dorcas ; and the tail is brown, in place of black, with a smaller amount of fawn at the root. Apparently the ears are longer than in the dorcas. THE RED-FRONTED GAZELLE (Page 258) The range of the Mongalla (not Mongola) race extends from Gondokoro, in Uganda, northwards to Ber, in the Mongalla district of the Sudan on the Abyssinian side of the Bahr-el-Gebel. The skull of the Libyan race of G. rufifrons differs from that of ¢zlonura by the greater length of the portion in front of the teeth. In rajffrons the length of the tooth-row is 2,4, in., and that of the part in front at; in ¢lonura these measurements are 2,8, and 1g. In the much smaller isabella they are 24 and 14%. Skulls and horns of the three species are figured on page 27. THOMSON’S GAZELLE (Page 259) As mentioned in the “ Addenda” issued with the original volume, Dr. E. Lénnberg (“Sjostedt’s Kilimandjaro-Meru Expedition,” Upsala, 1908, p. 46) gave the name of Gazella thomsont nasalis to the Kili- manjaro race of this species on account of the absence of a black nose-spot. ; Ignoring this, Mr. T. Knottnerus-Meyer, who refers the species to 14 SOPPIEMENT a separate genus (Ludorcas), recognises (Sz¢z.-Ber. Ges. naturf. Freunde, Berlin, Ig10, pp. 106-124) no less than thirteen local forms, which are regarded by him as species, although they are, at most, no more than races. Their names are (1) G. 4. daringoensis, Lakes Baringo and Solei; (2) 4 zahuroensis, Lakes Nakuro, Naivasha, and Elmenteita ; (3) 2 dbzedermannt, Shirati district; (4) 4 langheldi, Usukuma; (5) t. schillingst, from Lake Natron to Kilimanjaro; (6) 4 mzrzenszs, west side of Njiri Swamp; (7) 4 sabakzenszs, east side of same; (8) 2 bergert, Nairobi ; (9) 4 mundorostca, Mundorosi plains; (10) «4 ¢ypica, south of Kilimanjaro; (11) 4 wembaerensts, Wembare plains; (12) 4 manyarae, Lake Manyara; (13) ¢. vwwanae, Ruwana plains. Of these either No. 5 or No. 10 is probably identical with Dr. Lonnberg’s nasalts; Mr. Meyer regarding British East Africa as the typical locality of the species, whereas Dr. Lonnberg considers that this position is occupied by the Kilimanjaro race. Apart from certain skull-characters, the races recognised by Dr. Meyer are mainly distinguished by slight differences in the colour of the hair and shape of the horns. As it would occupy too much space to record their differences, and as the number of races may prove to be excessive, the quotation of the names must suffice. THE, BEISA (Page 284) The beisa of the Laikipia plateau, British East Africa, has been described by Mr. N. Hollister (Swecthsonian Misc. Collections, vol. \vi. No. 2, p. 7, 1910) as Oryx annectans, as it appears to form a link between the typical representative of the species and the fringe-eared Kilimanjaro race. It is, however, only a local race, and should be known as O. bezsa annectans. THE SABLE] ANZ ELOERE (Page 290) On page 35 of Dr. J. E. Gray’s “Catalogue of Ruminant Mammalia in the British Museum,” 1872, reference is made to a variety of the sable antelope, for which the name £7rk7z was suggested. Its supposed distinctness was based on a statement by Sir John Kirk in the Proceedings of the Zoological Society for 1864, that in the Batoka Hills, to the north of the Zambesi, all the sable antelope are rufous. — i i? fe ELAND 1 In 1910 Mr. E. Heller (Smzthsonian Misc. Collections, vol. liv. No. 6, p. I) proposed the name Osanna roosevelti for the sable antelope of the Shimba Hills, British East Africa, basing his description on a female skin. Compared with the typical South African animal, the specimen is stated to have the upper-parts much lighter, only the dark head-stripes, throat, and fore-legs being black, while the general body- colour is light chestnut. There is also less marked contrast between the dark and light face-stripes, the light ones being buffish yellow in place of white. The head of a male from the same region in the British Museum, presents, however, no appreciable difference in colour from Mashonaland bucks; and it is thus quite clear that the East African animal is, at most, nothing more than a local race of the sable antelope, which may be characterised by the paler colouring of the female, and perhaps by the relatively late age at which the dark livery is assumed. At present there is nothing to distinguish the British East African animal from fzppotragus niger kirki of the Batoka Hills; but if it should eventually be proved distinct, it should be known as /7. 7. roosevelt. Te be AND) (Page 305) In the sixth edition of Mr. Rowland Ward’s “Records of Big Game,” 1910 (p. 328), I have proposed the name Zaurotragus oryx seloust for the Mashonaland eland, as typified by the heads figured in Mr. Selous’s “A Hunter’s Wanderings,” one of which is reproduced in plate xii. of the volume to which the present contribution is a supple- ment. Mashona eland have an incomplete white chevron on the forehead, with a large frontal tuft of brown hair. LORD? DERBY S: EwAND (Page 314) The first paragraph in the text should read as follows :— This magnificent eland, of which a bull from the Bahr-el-Ghazal stood 5 ft. 8 in. at the shoulder, was first known in this country from Senegambian horns and skins sent home by Whitfield, collector for the menagerie then maintained at Knowsley by the 13th Earl of Derby. The name was given in 1847 by Dr. J. E. Gray on the evidence of a pair of horns, 16 SUPPLEMENT THE BUSHBUCK (Page 323) As stated in the “Addenda” to the original volume, the Mweru bushbuck has been described by Dr. Lonnberg (“ Sjostedt’s Kilimandjaro- Meru Expedition,” 1908, p. 48) as Tvagelaphus scriptus' meruensts. It is distinguished from masazcus by the lack of white body-stripes, and of a white spot below the eye, although the two cheek-spots are present. The general colour is dark reddish brown on the back and hind-quarters, passing into smoky brown on the shoulders and sides of the chest, while the under-parts are smoky brownish grey, with a white patch on the inner side of the upper part of the legs. A bushbuck from Nakuru, British East Africa, was described in 1909 by Dr. J. A. Allen (Bull, Amer. Mus. Nat. Fitst. vol. xxvi. p. 148) as 7. taederi, but may be regarded as a race, with the name of 7. s. tiaedert. It is stated to be allied to the imperfectly known 7. s. delameret of Somaliland, but differs in having the under-parts darker instead of lighter than the back, by the larger size of the white patches on the fore-part of the neck, and by the presence of a long white stripe on the front of each hind-leg corresponding to a black stripe on the fore-leg, instead of white stripes on both pairs. There is also a distinct crest along the back which is wanting in the type of delamerez. The locality of 7. s. menelki (supra, p. 325) is Arusi-Gallaland near the sources of the Webbe Shebeyli, at a height of about gooo feet. L. ¢. multecolor also occurs in the neighbourhood of Lake Zwei. THE NVALA (Page 331) On page 333 of the original volume there is stated to be a gap in the distributional area of the nyala, which occurs in the Gaza country of Portuguese East Africa, to the southward of the Sabi river, whence it extends to St. Lucia Bay, but is unknown in the great tract lying between that river and the Zambesi, although it reappears to the north of the latter in the Nyasa district. In 1910 I received a letter from a correspondent at Pretoria, who informed me that he has killed nyala to the south of Zambesi between that river and the Pungwe, although, for 1 Originally given as sy/vaticus, MOUNTAIN NYALA Ly obvious reasons, he is not at present desirous of revealing the exact locality. The only gap now remaining in the distributional area is formed by the tract between the Pungwe and the Sabi, and if the species does not exist there at the present day there can be little doubt that it did so formerly. Hie MOUNTAINS NY AEA Tragelaphus buxtont By far the most important addition to the big-game fauna of the continent made since the publication of the “Game Animals of Africa,” is the mountain nyala, typified by a specimen shot by Mr. Ivor Buxton in the Sahatu Mountains of Arusi-Gallaland, at a height of about 9000 feet ; this and other specimens being described by myself in the Zoological Society’s Proceedings for 1911 (p. 349). The conformation of the horns affiliates this antelope to the bushbuck group, from the other members of which it is distinguished by its superior size. From the nyala, which makes the nearest approach in this respect, 7rvagelaphus buxtonz differs in the reported identity of the colour in the two sexes, in the shorter coat and less bushy tail of the male, the presence of two white gorgets on the throat and chest, the absence of any marked difference in the general colour of the lower part of the legs from that of the body, and in the more open spiral formed by the more massive horns. In the type specimen, which is an approximately full-grown but young buck, the horns form about one complete turn, and have the general characters of those of the nyala, but are relatively heavier, and diverge more outwardly with an open spiral. They are obliquely ridged at the base, and the smooth terminal portion is worn yellow at the tip. The length along the outer curve is 37 inches, the basal girth 9+ inches, and the tip-to- tip interval 21 inches. In general colour the coat, which is rather long and coarse, is speckled brown-fawn, passing into dull tan on the sides of the face, and becoming darker on the front surface of the muzzle, and chocolate- brown on the forehead above the white chevron. The under-parts are lighter, but on the front of the fore-legs and the lower portion of the hind pair the tint becomes darker. There is a short dark brown mane on the neck, continued backwards as a mingled brown and white dorsal crest. The bushy tail is white beneath. The ears, which are much of the same type as those of the nyala, are of moderate width, 18 SUPPLEMENT bluntly pointed at the tip, and tubular for a considerable distance at the base; most of the long hairs on the inner edges being white, as is also much of the inner surface of the outer margin. The white markings include a not very distinct chevron between the eyes, the usual patches on the sides of the muzzle and chin, a pair of spots on each side of the face below the eye, and a smaller and fainter one behind the same, a narrow but deep gorget on the throat, and a wider but less deep one of a more lunate shape on the Upper part “Gf the chest aes curved row of nine spots— some of which are fainter than the rest—extends from a point about over the head of the thigh-bone to the back of the lower part of the shoulder. There is another white spot on each side of the buttocks. The inner surface of the thighs and of the upper portion of the fore-legs is dirty white.
