This species varies greatly in the intensity of the colours and in the extent of the black on the feet and nose. In one young specimen in the British Museum the black on the nose is quite deficient; though it has the bright colouring of the breeding-season, and is bright bay on the crown.

The specimen in the Museum of the London Missionary Society (No. 8 Blomfield Street, Moorfields, formerly in Austin Friars), Case 5, described by Colonel H. Smith under the name of A. Platous, is the size and has the horns and ears of an adult C. Grimmia, but differs in being paler, and having no dark colour on the nose or feet; but it is evidently much bleached. It has certainly no relation to the C. sylvicultrix, with which Colonel Smith was afterwards inclined to place it as a variety (Griff. A. K. Syn. v. 344).

There are three species which have been called Antilope Grimmia:1. The Capra sylvestris africana of N. Grimm, Misc. Cur. Norimb. 1705, 131. t. 13, the authority for Capra Grimmii, Ray, Syn. 80, and Linn. S. N. (ed. 10) 70. Moschus Grimmia, Linn. S. N. ed. 12, from the Cape, of a dull grey colour. Probably the Duyker.

2. Le Grimme of Buffon, H. N. xii. 307. 329. t. 41. f. 2, 3, from a head sent from Senegal by Adanson; the Antilope Grimmia of Desmarest, F. Cuvier, and H. Smith, &c.; the Cephalophus rufilatus.

3. The A. Grimmia of Pallas, with large ears and a black streak to the horns, like C. Campbelliæ, but is from Guinea. I know of no species common to the W. and S. coast of Africa, so that it is probably yet to be distinguished.

The "Fitomba" or "Philantomba" appears to be the generic name of all the W. African Cephalophi or Bush Antelopes.

3. CEPHALOPHUS CAMPBELLIÆ.

TOMBA.

The BLACK-FACED PHILAN

Grey and black grisled, beneath white; cheeks, neck and chest yellowish; forehead yellow, with a black streak on the nose widening on the forehead and ending in a tuft behind the horns; feet and front of fore-legs reddish black; fur soft; hair grey, with black ring and tip; ears elongate acute.

Antilope Grimmia, Pallas, Spic. Zool. xii. 18. t. 1?-C. Burchellii, var. (C. Campbellia), Gray, Cat. B. M. 162.-C. Campbelliæ, Gray, Ann. and Mag. Nat. Hist. 1846, 164; Knowsley Menag. 9. t. 2. f. 3. Inhabits S. Africa. Brit. Mus.

This species is at once known from the Duyker by being much darker and distinctly grisled or dotted, and the under side being much whiter.

We have an adult female of this species sent us as A. mergens, var. Burchellii, by M. Sundevall (the other specimen of the same name being a true Duyker), and a young specimen which has been in the British Museum for several years, sent from Africa, under the generic name of Philantomba, by Mrs. Campbell.

The A. Grimmia of Pallas, Spic. Zool. i. 18. t. 3, which he describes as grey grisled, becoming brownish ash on the buttocks; throat, chest and beneath the body white; head and neck yellowish

grey; a black streak between the horns, forming a fascia on the forehead and broader on the nose; fur softer than the Deer, but rough, of lower part of the neck rougher and more lax; feet and line on forelegs blackish; tail black above; ears rather acute: inhabits Guinea; agrees in most respects with this species, but most probably is yet to be procured from W. Africa.

*** Knees not tufted; ears moderate, acute; horns short, conical, thick.

4. CEPHALOPHUS MADOQUA. The ABYSSINIAN BUSH BUCK. Yellowish brown, slightly punctulated with black; neck yellowish; limbs blacker; face-streak and feet black; hair rather rigid, closepressed, reddish grey at the base, end polished yellow brown, with dark tips; forehead reddish.

Antilope Madoqua, Rüpp. Abyss. t. 7. f. 2; Sundev.-Madoqua, Bruce's Travels, vii. 360. t. 56.-C. Madoqua, Gray, Knows. Men. 9. Inhabits Abyssinia. Mus. Frankfort.

This species is very distinct from C. coronatus, being darker, and the fur more rigid and close-pressed.

5. CEPHALOPHUS CORONATUS. The RED-CRowned Bush BUCK. Pale yellowish brown; middle of back and front of fore-legs varied with a few scattered black hairs; crown bright bay; crest blackish brown, bay in front; feet and streak up the nose blackish; inside of ears, chin, throat, chest, belly and inner side of legs whitish; horns short, conical; ears about half as long as the head, acute.

Cephalophus coronatus, Gray, Ann. and Mag. Nat. Hist. x. 1842, 266. 1846, 164; Knowsley Menag. 9. t. 6. f. 1, 2.

Inhabits W. Africa; Gambia, Macarthy's Island. Mr. Whitfield called it The Coquetoon. Brit. Mus.

**** Knees not tufted; ears moderate, rounded; horns conical, thick; without any streak over the eyes.

6. CEPHALOPHUS SYLVICULTRIX. The WHITE-BACKED BUSH BUCK.

Blackish brown, minutely grisled; hair brown, with whitish tips; back with a large yellowish white spot, narrow in front; throat, chest and belly redder; crown, nape and legs darker; horns ?

Antilope sylvicultrix, Afzelius, N. Act. Upsal. vii. 1238; H. Smith, G.A. K. t. 187.-C. sylvicultrix, Gray, Knowsley Menag. 10. t. 8. f. 1. Inhabits Sierra Leone, in swampy places. Brit. Mus. Varies in the size of the dorsal spot.

In the British Museum is a young male: length 29 inches; height 18; tarsus 6.9.

7. CEPHALOPHUS OGILBII. The BLACK-STRIPED BUSH BUCK. Pale bay brown, with a deep black dorsal streak; beneath pale; crown and haunches brighter bay; neck and withers, and sides of the

dorsal line varied with deep brown hairs; streak up the fore-leg, upper part of hock, feet (above the hoof) and end of tail blackish ; horns short, thick, conical, very rugose on the inner front edges of the base.

Inhabits Fernando Po (J. Thompson, Esq.). the size of the preceding.

Brit. Mus. Not half

8. CEPHALOPHUS DORSALIS. The BAY BUSH GOAT.

Dark bay; shoulders and legs darker; hair brown, a few on the haunches white-tipped; crown and nape, broad streak along the back to end of tail black; spot over each eye; lips, sides of chin, front of chest, under side of tail and inside of thighs pale brown.

Cephalophus dorsalis, Gray, Ann. and Mag. Nat. Hist. 1846, 165; Knowsley Menag. 10. t. 7. f. 1.

Inhabits Sierra Leone: called Bush Goat. Brit. Mus. The head is very large, the skull short, broad, forehead rounded.

9. CEPHALOPHUS NIGER.

The BLACK BUSH BUCK.

Sooty black, greyer in the front half of the body; chin, throat, abdomen and inside of thighs grey; forehead and crown dark bay and black mixed: cheeks pale brown and black varied; tail, end whitish. Antilope niger, Mus. Leyden.-Cephalophus niger, Gray, Ann. and Mag. Nat. Hist. 1846, 165; Knowsley Menag. 10. t. 7. f. 2.

Inhabits Guinea. British Museum. Sierra Leone (Mr. Whitfield). Knowsley Museum.

In the British Museum there is a male from the Leyden Museum, nearly as large as the former.

10. CEPHALOPHUS NATALENSIS. The NATAL BUSH BUCK. Bright red bay; nape, withers and feet varied with dark grey hairs; nose-streak short, blackish; lips, chin, upper part of throat and end of tail white; lower part of cheeks, throat and abdomen pale yellowish; crown and tuft bright red; horns short, conical.

Antilope natalensis, A. Smith, S. Afr. Quart. Journ. 217; Illust. Z. S. A. t. 32.-Cephalophus natalensis, Gray, Knowsley Menag. 10. Inhabits S. Africa. Port Natal. Brit. Mus. Five specimens of different ages. Resembles C. Ogilbii in size and colouring, but wants the dorsal streak. The females are horned.

11. CEPHALOPHUS RUFILATUS. The COQUETOON.

Deep reddish bay; legs, nape, streak on the nose to the crown and broad streak on the back blackish grey; ears blackish; crest and upper part of tail black; cheeks rather paler; chin and abdomen pale yellowish; inside of ears whitish, with a brown spot on the outer side; horns conical, rather elongate, obscurely annulated, slightly recurved.

Cephalophus rufilatus, Gray, Ann. and Mag. Nat. Hist. 1846, 166; Knowsley Menag. 10. t. 9.-Antilope Grimmia, H. Smith, G. A. K. v. 266.—Le Grimme, Buffon, H. N. xii. t. 41. f. 2, 3?

Var. 1. Sides paler, greyish red; forehead rough.

Le Grimme, F. Cuv. Mamm. Lithog. t. . not good.
Inhabits Sierra Leone, called Coquetoon. Brit. Mus.

The hair is rather paler at the base, of the dorsal streak grey, with a blackish tip.

M. F. Cuvier's (Mamm. Lithog. t. .) figure is the pale variety, which Mr. Whitfield regards as distinct; he says it is called Grimme by the natives: the separate head of Cuvier's plate appears to have been taken from the Guevei.

**** Knees not tufted; ears moderate, rounded; horns short, thick, conical; head with a pale streak on each side over the eyes to the base of the horns.

12. CEPHALOPhus MaxwelLII. The GUEvei.

Grey brown or sooty brown; sides of head and body greyer; chin, throat, chest and belly whitish grey; abdomen and front of thigh white; broad streak over each eye to the base of the horns yellowish white; feet and end of nose rather darker; fur rather rigid; hair uniform.

Antilope Maxwellii, H. Smith, G. A. K. iv. 267.-A. pygmea, Pallas, Spic. xii. 18?-The Guevei, Buffon, H. N.-A. pygmea (Guevei), F. Cuv. Mamm. Lithog. t. good.-A. Frederici, Laur.; Sundev. -A. Philantomba, Ogilby, P. Z. S. 1836, 121; 1839, 27.-Cephalophus Maxwell, Gray, Knowsley Menag. 11. t. 12.

Inhabits W. Africa. Brit. Mus.

The adult male in the British Museum is bright sooty brown, darker near the rump; the female is nearly uniform pale grey brown. It is well figured by M. F. Cuvier. It is known from C. monticola by being larger, by the whiteness of the eye-streak, and of the front of the thigh and chest.

13. CEPHALOPHUS MONTICOLA. The NOUMETGE or CAPE

GUEVEI.

Grey brown; streak over the eyes, legs and outer part of thighs rufous; feet grey brown; chin, chest, abdomen, and under side of tail and inside of ears white; fur soft, grey, with intermixed rather rigid black hairs.

Antilope monticola, Thunb. Stockh. N. H. xxxii. t. 5.-A. cærulea, H. Smith, G.A. K. v.855; Daniell's Afr. Scen. t. ; Harris, W. A.A. t. 26.-A. perpusilla, H. Smith, G. A. K. v. 854.-A. pygmea, Licht. Saugth. t. 16; Sundevall.-Cephalophus monticola, Gray, Knowsley Menag. 11.

Inhabits S. Africa. Brit. Mus.

The colours vary in intensity; in a female in the British Museum, the rufous colour of the thighs and the white of the chest are more distinct than in the male, but this may depend on the season when

they were killed. A very young fawn (perhaps hardly born), which was brought home from the Cape by M. Verreaux, is darker, and the reddish tint extends over nearly the whole body.

Thunberg described the South African species, but says that there is a specimen in the Stockholm Museum, brought by Afzelius from Sierra Leone, which agrees with his animal; so he evidently did not observe the difference between the two species.

14. CEPHALOPHUS

GUEVEI.

MELANORHEUS. The BLACK-RUMPED

Grey brown; throat and sides paler; rump and upper part of tail black; chin, chest, abdomen, back and front edge of thighs and under part of tail white; narrow streak over the eyes whitish; feet like the back; fur soft, pale grey, with intermixed rather rigid black hairs.

Cephalophus melanorheus, Gray, Ann. and Mag. Nat. Hist. 1846; Knowsley Menag. 11. t. 10.-C. Philantomba, Gray, Cat. Mamm. B. M. 163 (not H. Smith).

Inhabits Fernando Po (J. Thompson, Esq.). Brit. Mus.

This species is coloured like the Guevei from W. Africa, but smaller, and have the soft fur and interspersed black hair of the Cape Guevei, C. monticola, but they are easily known by the black mark on the

rump.

15. CEPHALOPHUS PUNCTULATUS.

The GRISLEd Guevei.

Dark fulvous brown; sides and legs rather paler; narrow streak over the eyes and inside of ears pale brown; chin, throat, chest, belly and front of thighs and under part of tail white; hair grey at the base, with brown ends and yellow subterminal rings; crown and upper part of tail darker; feet pale, varied.

Cephalophus punctulatus, Gray, Ann. and Mag. Nat. Hist. 1846; Knowsley Menag. 11. t. 11. f. 1.

Inhabits Sierra Leone. Brit. Mus. A young specimen presented by Colonel Sabine, R.E.

It is at once known from the other Gueveis by the fulvous colour which is produced by the yellow subterminal rings of the hairs.

Colonel H. Smith indicates a species under the name of C. Philantomba, but so indistinctly, that it is impossible to know for what it is intended.

16. CEPHALOPHUS WHITFIEldii.

VEI.

The WHITE-FOOTED GUE

Yellowish ash; shoulders, outside of limbs and hinder parts of back rather darker; ears and crown pale yellowish brown; streak over the eyes, cheeks, throat, belly, inside of the limbs and ring round the feet above the hoof ashy white; hair ashy grey; of the back brown at the end, with a yellow tip.

Cephalophus Whitfieldii, Gray, Knowsley Menag. 12. t. 11. f. 2. Inhabits Gambia (Mr. Whitfield). Mus. Brit. Young.

Smaller than the Grisled Guevei, and much paler and yellower.
