Capt. Swayne has referred the Bushbuck of the Webbe to _T. decula_, but this is certainly not correct, as, according to his own description, it has “four or five white stripes, and sometimes as many as thirty white spots.” In some skins from Sen Morettu, on the Webbe, received from Capt. Swayne, now in the British Museum, there are four or five distinct white stripes on the flanks, both in adult and immature males, a few white spots on the hind-quarters, and a row of white spots extending along each side of the body above the belly. Although in some respects this form comes nearer to _T. scriptus_, we think it better for the present to regard it as a subspecific form of _T. roualeyni_, which, using Mr. Pocock’s subspecific term, we call _T. roualeyni fasciatus_, and describe as follows:— Height at withers about 26 inches. Head and legs of the same colour and pattern as in _T. roualeyni_ and the other species of this section of the genus. General colour a reddish yellow, brighter on the hind-quarters, and distinctly blacker in the dorsal region, where the hair assumes a dusky greyish-brown hue. Body marked with four or five very distinct, mostly broad, white stripes, a row of white spots running along above the belly and a few white spots on the haunches. Hair on body shorter than in _T. roualeyni_. No distinct collar of short hair round the base of the neck, as in _T. roualeyni, T. sylvaticus_, and _T. scriptus_, the entire neck being covered with a coating of short silky hairs of the same length as those of the head, much shorter than those of the body, and of a dusky, greyish-brown colour. Young male redder in colour than the adult and equally strongly marked with white. The skull of a subadult male gives the following measurements:—Basal length 8·25 inches, orbit to muzzle 4·6, greatest width 3·75. In the British Museum are a skull of the typical _T. roualeyni_ of the Limpopo, procured by Gordon Cumming, and a skin and skull from the Zambesi obtained by Mr. Selous. There is also in the Museum a good series of skins and skulls of this species from Zomba, Nyasaland, and its vicinity, transmitted by Sir Harry Johnston and Mr. A. Sharpe, of which we have already spoken, and from one of which our figures of the adult skull (pp. 126, 127) have been taken. From British East Africa the National Collection possesses the mounted adult male from Manda Island presented by Sir John Kirk (and figured on our Plate XC., as already mentioned), also a mounted female from the same source obtained in British East Africa about one hundred miles inland at 6° S. lat. Besides these there are Capt. Swayne’s specimens from the River Webbe in the interior of Somaliland, already referred to. We are not aware that any examples of this Bushbuck have been brought to Europe alive. _November_, 1899. 124. DELAMERE’S BUSHBUCK. TRAGELAPHUS DELAMEREI, Pocock.
