1910,] CUTANEOUS SCEXT-OLAXDS OF RUMIXAXTS. 881 



The pedal glands were well developed, but different from these 

 of Mculoqua. On l)oth front and hind legs they consisted of large 

 wide-mouthed deep pouches passing up betweeii the antepen- 

 ultimate phalanges of the feet, and opening some distance above 

 the proximal margin of the hoofs. The anterior wall of each was 

 formed by a closely folded web, and the posterior by an equally 

 closely folded posterior web ; but neither of these webs extended 

 so far down the foot as in Madoqaa, the posterior web of the hind 

 foot not nearly reaching the heels, and extending only a little 

 farther than in the Tragulina, and reaching only a little farther 

 than the anterior web. This suggests that the heels, as well as 

 the rest of the hoofs, are capable of very wide separation. On 

 the front foot, on the contrary, the posterior web was longer, ;ind 

 reached almost to the heels, extending considerably lower than 

 the anterior web. Its inferior extremity, moreover, was turned 

 slightly forwards for a short distance, making a distinct ridge, 

 something like that of Dorcotragus. Although the walls of the 

 pocket were only scantily clothed with haii-, the rest of the inter- 

 digital space Avas clothed with- long hairs, and the edge of the 

 posterior web forming the postei-ior lip of the pocket wns 

 furnished with long haii's projecting downwards, as in Madoqua 

 and Doi'cotragus. There were two pairs of teats. 



Raphicerus sp. ? or Nesotragus sp. ? 



I am indel)ted to Mr. Gerrard for a front and a hind foot w itliout 

 supplementary hoofs, and therefore referable probably either to 

 Kajjhicerus or Xesotragus. These are worth describing, because 

 they are structurally nearly intermediate between the feet of 

 Raphicerus camjiestris and of Ourehia nigricaudata. 



In the hind foot the interdigital cleft was open in front 

 throughout nearly the whole of its length, being only slightly 

 overlapped above by a short angular fold of integument. Its 

 posterior wall descended with a gradual curvature downwards, 

 meeting the skin of the back of the pastern considerably nearer 

 the heels than in R. campestris, and forming a strong thickened 

 tie, which was turned slightly forwards. 



The interdigital cleft on the front foot hardly difiered from 

 that of Ou.rehia nigricaudata., except that its upper extremity was 

 overlapped to a greater extent, although not so much as in 

 R. camjiestris, by the antero-superior integumental web. 



Since the hind foot was of a more rusty tawny hue than the 

 front foot, and measured half an inch moi-e from the fetlock to 

 the tip of the hoof, there can be very little doubt that it belonged 

 to a different species or subspecies, possibly to a different genus, 

 of Antelope. Considering the differences the two feet present 

 from those of R. campestris, the evidence is, I think, in favour of 

 their belonging to the genera JSFeoti'agK.s or Xesotragus, perhaps 

 one to moschatiis and the other to livingstonianus.
