small oblique plications of the lining membrane. The clitoris is 

 imperforate ; on each side of it there is a tumid process of integu- 

 ment, making a kind of prepuce. From these processes two 

 ridges pass backward to the sides of the vulva, of which they 

 constitute the labia, and between these there is a groove runnino- 

 from the clitoris to the urethro-sexual canal. In the tail-less 

 Apes the fundus uteri acquires increased breadth; the general 

 walls are thicker than in Monkeys ; but the entire organ is longer 

 and more slender than in the human subject. 



§ 394. In Bimana. — The ovaria of the adult female are oval, sub- 

 depressed bodies, fig. 548,/, suspended by the layers of peritoneum 

 continued from their surface to the ' broad ligament,' within which

is a cord of sclerous tissue passing from the uterine end of the 

 ovary to the womb, and called ' ligamentum ovarii,' ib. h : a pro- 

 cess of the pavilion connecting these to the opposite end of the 

 ovary is called ' tubo-ovarian ligament,' ib. e. The depression of 

 the ' broad ligament ' between ovarium, f 9 and oviduct, c, shown 

 by raising the former, answers to the ' capsula ovarii ' of lower 

 Mammals. The anterior surface is less convex than the posterior 

 one. The ovisacs expand in a dense tissue or ' stroma,' fig. 534, in- 

 closed in a sclerous tunica albuginea : with the adventitious tunic 

 which the ovisacs derive in their enlargement from the stroma, 

 they form the cavities called * Graafian vesicles/ In the young 

 adult female the surface of the ovary is smooth : it. afterwards 

 becomes scarred by the cicatrices of ruptures caused by discharges
