136 Mr. R. I. Pocock on some 



Adenota kob or Hippotragus niger ; but whether it repre- 

 sents a rudimentary or vestigial condition of the pouch-like 

 preorbital gland of Capricornis must be left an open 

 question. 



The pedal glands and the structure of the feet resemble in 

 evei'y respect those of N. raddeanus, described and figured on 

 p. 854 of my previous paper. Inguinal glands, as noticed in 

 1910, are absent. 



The rhinarium (fig. 2, C, D) is large and naked on its 

 upper surface almost as far back as the posterior angle of 

 the nostril, but in the middle line above, the hair grows 

 forwards, foiming an angular point. Beneath the nostril 

 laterally there is a comparatively wide area of smooth naked 

 skin. In front the rhinarium extends to the edge of the 

 upper lip as a narrow grooved strip of corrugated integu- 

 ment which expands above to right and left beneath the 

 inner angle of the nostrils, and the expanded portion is 

 flanked on each side by an area of smooth naked skin. 



The penis (fig. 2, G) is cylindrical, slightly expanded 

 distally, then gradually narrowed to the apex, beyond which 

 the end of the urethral canal is prolonged as a tube for a 

 short distance. 



Two points of special interest may be noticed in con- 

 nection with these observations : namely, the similarity of 

 the penis to that of Budorcas, described below, and the 

 presence of the preorbital gland, which serves to link Ncemo- 

 rhedus closer with Capricornis than was previously supposed 

 to be the case. 



Genus Budorcas, Hodgson.

The death of a male example of this species from N.W. 

 Bhotan enables me to verify and extend my account of the 

 external characters of this genus published in 1910, and 

 based partly on this example when alive and partly upon 

 a dried skin of B. taxicolor tibetanus lent to me by 

 Mr. Gerrard. 



The rhinarium (fig. 3, A, B) is continued inferiorly to 

 the edge of the upper lip as a narrow mesially grooved strip, 

 which is longer than in Namorhedus owing to the 

 greater depth of the upper lip. Laterally an area of naked 

 skin, narrower than in Ncemorhedus, is continued with a bold 

 curve beneath the widely expanded nostrils, and curving 

 round their posterior extremities passes into the dorsal
