WATSON ON T H E [May 1, 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 reflected to the base of that body to become continuous with its cutaneous 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 rugse 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 corresponding portion of that body. Labia ?-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 in this region is devoid of hair and, close to the base of the clitoris, is thickly studded with numerous little depressions. 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, although here they are by no means so numerous as in the perineal region. They are entirely absent from the abdominal surface of the prepuce, as also from the upper part of the perineum. Immediately 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 position with regard to them ; that is, it lies in the anterior commissure. It is to be observed, however, that there is no vaginal aperture between the folds. The integument forming them possesses the structure 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 Felidae. 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 subcutaneous fat. Anus and anal-gland pouch.-Immediately above the scrotal pouches the surface of the skin is somewhat depressed, the margins |
