fold of thick integument which, rising from the level of the perineum, 

 passes as far forward as the extremity of the glans, and is then re- 

 flected to the base of that body to become continuous with its cu- 

 taneous covering. It is attached by a distinct frsenum to the pointed 

 posterior angle of the glans, but is otherwise free, very loose, and 

 rugose, and can be readily drawn out so as completely to conceal the 

 glans of the clitoris. Under ordinary circumstances, however, it 

 would appear that the preputial integument is thrown into circular 

 rugae around the clitoris, and thus leaves the extremity of the glans 

 uncovered. The colour of the skin forming the prepuce resembles 

 that of the glans, being bluish externally, but where it comes into 

 contact with the glans it assumes the flesh-colour of the correspond- 

 ing portion of that body. 



Labia 1 — The integument of the perineum, continuous with that 

 which forms the prepuce, is of the same bluish colour as high as the 

 lower margin of the anus, where it changes its appearance. The 

 whole of the skin iu this region is devoid of hair and, close to the 

 base of the clitoris, is thickly studded with numerous httle depres- 

 sions. These depressions equal in size the head of a pin, and are 

 so closely placed that the intervals between them are less than the 

 depressions themselves. The integument of the perineal surface of 

 the prepuce is also studded at its base with these depressions, al- 

 though here they are by no means so numerous as in the perineal 

 reo-ion. They are entirely absent from the abdominal surface of the 

 prepuce, as also from the upper part of the perineum. Immedi- 

 ately above (perinead) the clitoris the skin is thrown into two 

 longitudinal folds which bound a shallow groove. These folds are 

 by no means well marked, but correspond in position to that of the 

 labia in other animals. Should they, as I believe they do, represent 

 these structures in this animal, the clitoris occupies the usual posi- 

 tion with regard to them ; that is, it lies in the anterior commissure. 

 It is to be observed, however, that there is no vaginal aperture be- 

 tween the folds. The integument forming them possesses the struc- 

 ture already described ; but between their upper extremities and the 

 margin of the anus, the skin, although devoid of hair, loses the little 

 depressions already referred to. 



Scrotal pouches.— The cutaneous elevations which I have so 

 named are situated immediately below the anus, one on either side 

 of the middle line, and remind one, forcibly in respect of position, of 

 the scrotum in many of the Felidse. Each is about the size of a 

 filbert, and, unlike the rest of the perineum, is covered with delicate 

 hair of a light brown colour. The presence of these pouches adds 

 much to the deceptive appearance of the female, and, combined with 

 the other peculiarities, renders the identification of the sex a matter 

 of difficulty. These pouches when cut open are seen to be mere 

 pouch-like elevations of the skin, and do not lodge any part of the 

 generative apparatus. Each is filled with a little mass of subcutane- 

 ous fat. 



Anus and anal-gland pouch. — Immediately above the scrotal 

 pouches the surface of the skin is somewhat depressed, the margins
