(Plate LI.) 



In Mr. E. Lort Phillips's "Notes on the Antelopes of Somali-Land" 

 (P. Z. S. 1885, p. 930) is mentioned a Gazelle under the name of 

 " Flabby-nosed Gazelle," the single specimen of which, in deter- 

 mining Mr. Lort PhiUips's species, I reserved for future examination. 



I was in hopes of being able to have the bones removed from the 

 head of the single specimen obtained, in order to ascertain whether 

 there is not some peculiarity in the frontal and nasal bones to 

 accompany the extraordinary development of the nose in this 

 animal. Not having been able to obtain the necessary facilities for 

 this purpose (which, seeing that the specimen is unique and has 

 been excellently mounted, was not much to be wondered at), I will 

 content myself with again exhibiting the head of this remarkable 

 Antelope (Plate LI.), and remarking that I think there can be 

 no question of its belonging to an undescribed species, which I 

 propose to call Gazella naso. Gazella naso, as its name implies, is 

 sufficiently distinguishable from all other known members of the 

 genus by having the extremity of the snout above the nasal openings 

 developed into a large flabby wrinkled mass, which is scantily covered 

 by short hairs of a grey colour. Above this elevated mass the face 

 is crossed by a broad black bar. Above that again the centre of 

 the forehead and space between the horns is covered by dense fur of 

 a chestnut-red colour. This chestnut-red forehead is bordered on 

 each side by two broad white longitudinal stripes, which extend from 

 the base of the horns down to the nostrils. This longitudinal 

 stripe is again bordered above the eye on the inside to below the eye 

 on the outside by an indistinct blackish stripe. The tear-pits below 

 the eye seem to be particularly large and well developed. The rest 

 of the fur of the head and neck is of the sandy colour usual in most 

 species of this genus. The ears, which are long and rather narrow, 

 are of a greyish colour. In the size and sliape of its horns G. naso 

 does not differ materially from other species of the group allied to 

 G. dorcas. The length of the horns in the present specimen, from 

 the base to the tip, is about 9| inches ; the breadth of the skull 

 between the eyes is 1*7 inch ; the length from the occiput to the end 

 of the nose about 8 inches ; the length of the ear is 6 inches. 



As regards the Neotragus, of which specimens were obtained by 

 Mr. Phillips and were likewise left undetermined in the same com- 

 munication (see P. Z. S. 1885, p. 932), I have now compared the 

 skull and the skin brought by Mr. Phillips with specimens in the 

 British Museum. As regards the skin there is such variation in 

 the coloration of the fur of Neotragus that I do not think much 

 reliance can be placed on the somewhat abnormal appearance of this
