218 Mr. R. I. Pocock on some 



round the upper lid of the nostril. Viewed from the front 

 it is exceedingly wide and laterally attenuated, with a 

 concavo-convex, sinuous upper edge. The philtrum, which 

 is broad, angular, and ungrooved, is inferiorly abbreviated, 

 ending in a point a little above the middle of the upper lip, 

 the lower portion of which is continuously hairy across the 

 middle line. The surface of the rhinarium is transversely 

 striated, not roughened and tessellated. 



In his paper on the anatomy of the Gnu, Lonnberg 

 (K. Vet.-Akad. Handl. xxxv. no. 3, p. 48, 1901) paid no 

 special attention to the rhinarium, contenting himself with 

 a reference to the descriptions published by others, notably 

 by Sclater and Thomas in the ' Book of Antelopes/ vol. i. 

 This brief description, however, contains no mention of the 

 pouches in the internarial septum, because they are com- 

 pletely concealed in dried skins. No doubt this fact 

 accounts for their having hitherto apparently escaped 

 detection. At all events I have not come across any record 

 of their occurrence. 



I am unable to suggest any explanation of the function" 

 of these pouches, unless they act as traps for the maggots of 

 parasitic dipterous insects (QSstrus) whose usual habit it 

 is to pass up the true nostril into the narial passages, where 

 they frequently set up serious disorders in Ruminants. At 

 all events, these parasites would be innocuous in the pouches. 



The penis (fig. 2, D) differs from that of Damaliscus py- 

 gargus in being apically attenuated, without trace of the 

 coidate thickening at the end, and in the termination of 

 the urethral canal in a short process on the left side of the 

 apex, beyond which it projects for a very short distance. 



Genus Gorgon, Gray. 

 Gorgon taurinus, Burch. (p. 906). 



An example of G. taurinus albojubatus, four and a half 

 months old, had the muzzle constructed as in Connoclwtes 

 gnon, except that the peculiarities were less exaggerated ; 

 it was less depressed and narrower and the rhinarium seen 

 from the front was deeper from above downwards and the 

 shortened philtrum showed a nairow groove. 



The preor bit a I gland was scantily clothed with long hair 

 and its surface was mesially depressed and saucer-like. 



The penis (fig. 2, E) of an adult male of the typical race 

 was less attenuated apically than in that of Connochcetes 

 gnouvLX\d the urethral canal was not prolonged beyond^ the 

 end of the glans.
