132 Mr. R. I. Pocock on some 



In 1910 I figured and described the postcornual gland of 

 the male example then living in the Zoological Gardens 

 when at their maximum of development, and a figure of the 

 head of a female sketched on the same day was added to 

 show the absence of the swelling. But in an adult female 

 that died on Dec. 4th, 1912, I discovered the gland to be 

 much better developed than would be expected from looking 

 *at the living animal, in which it is covered with the hair of 

 the parietal region. The glandular area is superficially- 

 like that of the male, consisting of a subcircular area of skin 

 marked with grooves. In section it is seen to be composed 

 of thickened skin thrown from front to back into four folds, 

 making ridges separated by valleys, the ridges gradually 

 increasing in height from the base of the horn posteriorly. 



It may be remembered that I described this gland in the 

 adult female in 1910 as consisting of a crescentic groove 

 behind the horn on each side, this description being taken 

 from the historic preparation in the Museum of the Royal 

 College of Surgeons. I have no doubt that this preparation 

 was made from a female that died during the period of 

 inactivity of the gland, and that the difference between this 

 specimen and the one I examined, which died in December, 

 is purely a question of seasonal development*. 



The rhinarium (fig. 2, A, B) is small. It borders the 

 nostril above as a narrow band, and it reaches inferiorly to 

 the edge of the upper lip as a narrow vertically grooved 

 philtrum ; but beneath the nostrils it only extends a short 

 distance on each side of the middle line, the rest of the 

 lower rim of the nostril being formed by hairy skin. 



The extremity of the penis (fig. 2, F) is slightly depressed, 

 and the urethral canal is prolonged beyond the extremity as 

 a pointed process which is a little longer than that of Ncemo- 

 rhedas, but shorter than that of Budorcas described below. 

 But in the sketch published by Gerhardt in 1906 the process 

 is at least as long as in Budorcas.

In 1910 I gave a brief account of the superficial appearance 

 of the pedal and preorbital glands of an example of this 



* It appears to me to be probable that the u postcornual sinus " 

 described by Hodgson as present in Procapra picticatcdata resembles in 

 structure tbe postcornual gland of the female Pupicapra when it is in the 

 stage of a crescentic groove. It is detectable in the newly born young of 

 Pupicapra in this condition.
