1884.] MAMMALS FROM SOMALI-LAND. 539 



results of Revoil's explorations no Antelope is mentioned among the 

 Mammals; but in the volume on his travels 1 (p. 369) the native 

 and French names are given of three species of this group. 



The skins which I now exhibit belong apparently to five species: — 



1. Strepsiceros imberbis, Blyth. 



Of the Lesser Koodoo I have only recently given a figure and 

 description in the Society's 'Proceedings' (P. Z. S. 1884, p. 45, 

 pi. iv.). In the collection now before us are two skius of this 

 species not materially differing from one another or from the 

 description above referred to. 



2. BoSELAPHUS CAAMA (CuV.). 



A single flat skin in the collection is certainly that of a species of 

 Boselaphus, and probably of B. caama, as Von der Decken is stated 

 to have found that species on Lake Jipe in Southern Somali-land 2 . 



3. Gazella walleri. (Plate XLIX.) 



Gazella walleri, Brooke, P. Z. S. 18/8, p. 929, t. lvi. 



The two skins which I now exhibit (see Plate XLIX. fig. 1) 

 probably belong to the same Antelope. They are at once recog- 

 nizable by the very wide and well-marked dark-brown dorsal line, 

 which in its widest part measures across the back from seven to eight 

 inches, and stands out in strong contrast to the lighter rufous of the 

 sides. The whole length of the skins, from the crown of the head to 

 the base of the tail, is about 4 ft. 6 in. ; the belly and undersides of the 

 limbs are white. One of the skins is probably that of an older animal 

 than the other, being rather larger and darker in colouring. 



From such imperfect specimens, although one may say that they 

 are those of some unknown Antelope, it would not be possible to 

 determine much. But fortunately I have been favoured by Mr. F. L. 

 James, of 14 Great Stanhope Street, with the loau of the perfect head 

 of an Antelope (see Plate XLIX. fig. 2) shot near Berberah in March 

 last, which evidently belongs to the same species. It will be at once 

 seen on comparison that the texture and colour of the hair on the nape 

 of the neck agree perfectly with those of one of the flat skins, so 

 nearly, indeed, that one might have supposed that the head and flat 

 skin may have belonged to the same individual. 



I was about to describe this Antelope as new when my attention 

 was called to the figure and description of the skull and horns of 

 an Antelope given by Sir Victor Brooke in the Society's ' Pro- 

 ceedings ' for 1878, upon which his Gazella walleri is based, as 

 probably belonging to the same species. In order to endeavour to 

 set this question at rest I have borrowed from the Rev. H. Waller one 

 of the specimens upon which Gazella walleri was based. As will 

 be seen by comparison of the skull and horns thus kindly loaned to 

 me with the mounted head belonging to Mr. James, the general
