In the typical species, numerous trans- verse and prominent rugic are developed internally at the lower part of the uterine cavity ; they are somewhat irregularly dis- posed in parallel rows, and are more crowded together towards the os tinea; where they are split up, as it were, into fine longitudinal lamellae, imparting to the os, when viewed from below, a peculiar radiated aspect. This latter feature is very striking in the Camels and in the Giraffe'. The vaginal mucous membrane («) is smooth throughout, and contracted interiorly at the external orifice. In horned Ruminantia the clitoris is placed just within the vitlvn, but external to the vaginal outlet in the Camelidae (Owen). Preputial follicles also occur in the female ruminant as well as Cowperian glands, which are situated near the root of the clitoris. In the gravid uterus of the typical species, the foetal membranes—consisting of the chorion (1, fig. 367.), anmion, and allantois - Fig. 367. Portion of the cliorion of a Coic, showing the cotyledons. (From Gurlt.) are connected to the walls of the cavity by numerous small placentuIts or cotyledons (2, fig. 367.), which embrace and dove-tail with a corresponding series of processes developed from the uterus. The cotyledons are pro- ductions of the chorion, and have an oval or rounded shape, more or less compressed, the exposed surface being usually cup-shaped ; after the expulsion of the foetus these bodies come away with the membranes, and the uterine protuberances diminish considerably in size. In the Sheep and Cow the number of the plaeentute varies from about seventy to a hundred. Like the chorion, the anmion is highly vascular. The allantois exists in the form of a closed sac, and only partially covers the amnion. In the Cameline ru- minants the ovum is retained in situ by a
