although very short, are somewhat basally expanded ; the skull has 

 a convex frontal region, and the hoofs appear to be relatively long. 



The Cameroons and the Gaboon are the home of this species, 

 which is a bush-hauntine^ animal. 



ALEXANDER'S DUIKER 



( Cephalophus eland i) 



A duiker from Bambili, in the Welle Valley, Congo Territory, 

 obtained during the Alexander-Gosling expedition from Nigeria to 

 the Upper Nile, and named after Captain Claud Alexander, was 

 described by Messrs. Thomas and Wroughton in the Annals and 

 Magazine of Natural History for 1907 (ser. 7, vol. xix. p. 386) under 

 the above name. It is near akin to nigrifrons both in size and 

 colour, but of a much darker and richer tint ; the general colour 

 being nearly " burnt-sienna " above, and only slightly paler on the 

 flanks and under-parts. There is, however, a dark stripe on the 

 middle line of the latter. Certain characters also distinguish the 

 skull from that of nigrifrons. 



THE RUDDY DUIKER 

 ( Cephalophus rubidus) 



Under this name Mr. O. Thomas described in the Proceedings 

 of the Zoological Society for 1901, vol. ii. p. 89, a small duiker 

 from the Ruwenzori district which appears to be nearly related to 

 Cephalophus nigrifrons, but has a thicker and more woolly coat, a 

 deeper and more uniform general colour, and a larger extent of black 

 on the lower part of the hind-legs. 



The general colour of the thick, close, and slightly woolly fur is 

 uniformly rich chestnut-rufous, the basal portion of the hairs being 

 rather greyer, and along the middle line of the back, especially near 

 the loins, these greyer bases become more decidedly grey-brown, and, 

 by showing through, communicate a darker shade to the aforesaid line. 

 On the neck the hairs take the usual backward direction ; the middle 

 line of the back is rather browner than elsewhere, and there is a white 

 chin -patch. The under-parts are paler rufous, becoming whitish 

 between each pair of legs. From the shoulders and hips the colour
