actabout one-third the lengthof the vagina : the prepu-tium clitoridis opens by atransverse crescentic fossaanterior to the urogenitaloutlet: the crura clitoridisembrace the urogenitalpassage before uniting, onits fore wall, into the bodyof the clitoris : the glansis subbilobate.1 Rectum, vagina and urethra, Stenops tardigradus. lxix. In the MongOOSe and other species of true Le-mur, the uterus communicates with the vagina upon a distinctvalvular prominence or os tincae ; but the clitoris is situated morewithin the verge of the vulva than in Cliiromys, and is perforatedby the urethra. The rugae of the vagina are well developed, andare of two kinds ; the stronger ones are longitudinal, in the inter-spaces of which are smaller transverse or oblique folds: theseassume a penniform arrangement near the outlet. The clitoris isinclosed in a large and thick internally plicated prepuce. Theexternal labia are continued from the dorsum of the clitoris; within ccxni. p. 97, tab. 3, figs. 2 and 3,

FEMALE ORGANS OF QUADRUMANA. 703 these there are two smaller folds, or labia minora, continued fromthe sides of the clitoris to the opposite part of the vulva; and onthe internal surface of each of these folds there is a thick longitu-dinal process of membrane projecting like the carunculae myrti-formes, into the cavity of the vagina. In Platyrhine Monkeys the uterus is long and narrow, with atruncate fundus, the angles of which are not produced into cornua : it begins to show thicker muscular walls. The os tincae is Dila-te biate: the urogenital tract is relatively longer than in Lemur,equalling that of the vagina. The clitoris is of unwonted length,and is pendent outwardly, like the penis of the male, in the Spider-Monkeys (Ateles) : it is not perforated by the urethra; this opensupon a longitudinal fold extending from the constricted limit ofthe proper vagina to the vulva. In Catarhines the urogenital tract is always much shorter thanthe vagina, and the uterus is long and slender.
