FEMALE ORGANS OF QUADRUMANA. 701 



margin of the capsule. The oviduct runs a short and tortuous 

 course along the anterior part of the ovarian capsule to the horn 

 of the uterus: both cornua present, in the unimpregnated Leopard, 

 the form of simple, straight, narrow, flattened tubes, with a 

 smooth and even internal surface, and they open into the common 

 uterine cavity half-way between their external union and the 

 vagina. The os tinea) is very prominent, and is beset with 

 numerous short papillose processes : in the Hyaena it is not papil- 

 lose. The vagina in the Leopard is a narrow canal, with a few 

 smooth longitudinal ruga) internally, which terminate abruptly at 

 the beginning of the urogenital passage : in the Hyaena the vagina 

 is wider with more produced longitudinal folds. The internal 

 surface of the urogenital passage is beset with coarse papillae, the 

 larger ones being aggregated in longitudinal groups : at its ter- 

 mination projects the clitoris : and at the sides of the passage, in 

 the Leopard, are the orifices of two large glands. The prepuce 

 has no ossicle or cartilage in the Viverrine or Feline Carnivora. 



§ 393. In Quadrumana. — The reappearance of Lissencephalous 

 characters of the female organs in the lowest members of the 

 present group indicates their derivation and divergence from some 

 antecedent common source. The smooth-brained Lemuridce with 

 gyrencephalous proportions of cerebrum show a common utero- 

 vaginal elongate cavity, as in certain Bruta, and an external 

 perforate clitoris, as in Insectlvora. 



In Perodicticus, Lichanotus , Otolicnus, Tarsius and Stenops 

 (both St. gracilis and St. tardigradus\ the ovaria are small oval 

 bodies, in adults often presenting a granulate exterior ; always 

 suspended in a depression, which is a rudiment of the capsule of 

 the broad peritoneal ligament. The oviducts commence by a 

 fimbriated extremity exterior to the ovaries, and pass in front of 

 those bodies in a tortuous course to the horns of the uterus. 

 These are short and wide, and begin by large obtuse extremities ; 

 they are lined by a smooth, thick, and seemingly villous mem- 

 brane. After the junction of the cornua the common uterine canal 

 presents internally a smoother surface, but begins to fall into a 

 number of fine longitudinal rugae: it is continued into the vagina 

 without any line or mark of distinction ; the same embryonal cha- 

 racter, as in Dasypus and Bradypus, being here persistent. The 

 rugae are more strongly developed in this canal, which terminates 

 by a round opening, fig. 547, b, half an inch anterior to the 

 rectum, ib. a. Immediately in front of the vagina is the clitoris, 

 ib. c ; it is a large and prominent body, perforated, like the penis 

 in the male, by the urethral canal, which opens upon a glans cleft
