[Mar. 16, There was no suborbital gland or crumen *, no vestige of the abdominal musk-sac of the malef, nor of the gland described by Brandt on the outside of the thigh*]:, nor of the tail-glands described by Hodgson§, in both cases in male animals ; nor were there any interdigital glands in either feet, the depressed space between the toes, where the glands usually open, being covered with hair||. The teats were two in number*^, placed on the hinder part of the abdomen, between the thighs, 1 inch in front of the anterior margin of the symphysis pubis, 3^ inches in front of the vulva, and y6^ inch apart; each was | inch in length, soft, flaccid, slender, cylindrical, slightly tapering, and with a rounded apex. They were placed upon a nearly bare oval space, 2 | inches across, and 1 inch from before backwards, having only a few long fine silky hairs upon it. The space between this and the vulva was covered with hairs resembling those of the remainder of the abdomen, though softer and finer, especially at the hinder part. A heart-shaped patch, y^ inch in diameter, surrounding the vulva, was covered with soft skin, perfectly bare, beset, especially near its margin and anterior portion, with numerous yellowish-white sebaceous glands. Within, but near the front end of this bare place, is situated the prominent conical eminence, formed by the anterior union of the labia, with a few short hairs upon it. Close behind this is the apex of the clitoris, at the anterior margin of the vulval orifice. The extremely short perinaeum, the margin of the anus, and the prominences formed by the tuber ischii, were covered with very short, flattened, adpressed hairs, which pass into those which clothe the triangular under surface of the very brief tail. It is not quite correct to describe, as is usually done, the long hairs of the tail as only covering the upper surface and sides of the organ, for they pass under and completely surround the extreme tip. The skin adheres very closely to the end of the very slender, elongated, terminal caudal vertebra. * In the Pudu the crumen is a distinct involution of thickened integument, lodged in a deep pit in the bone, with an aperture half an inch in length. The lining membrane is white and corrugated, and bas a few short, pointed, black hairs scattered over it. This organ, though generally present in the Cervidce, is rudimentary or absent in the Roe and in the South-American Deer of the section Coassus. It is also absent in Hyomoschus and Tragulus. t For an account of this organ and its peculiar secretion, which constitutes the " musk" of commerce, with references to previous descriptions, see A. Milne- Edwards's valuable memoir entitled " Recherches sur la Famille des Chevrotains," Ann. des Sciences Nat. 5C serie, tome ii. (1864), which also contains a description of the osteology of Moschus, and a short rUsume of Pallas's observations on its splanchnology. -f J. F.

This may be considered the most rudimentary or earliest stage of an interdigital gland. *[ In the male Pudu there were four. |
