terminal parts of the vas deferens. A diverticulum of the 

 urethra the uterus masculinus (u.m.) lies embedded in the 

 prostate gland close to the neck of the bladder. A small 

 pair of ovoid Cowper's glands (c.gl.} are situated just behind 

 the prostate close to the side of the urethra. The terminal part 

 of the urethra traverses a cord of vascular tissue, the corpus 

 spongiosum (c. s.), which forms the dorsal portion of the penis, 

 which is strengthened ventrally by two corpora cavern osa 

 (c. c.\ A loose fold of skin, the prepuce, encloses the penis. 



In the female the ovaries (Fig. 288, ov.) are small ovoid 

 bodies attached to the dorsal wall of the abdomen behind 

 the kidneys. The Graafian follicles enclosing the ova form 

 only very small rounded projections on their outer surface. 

 The oviducts in the anterior part of their extent (Fallopian 

 tubes) are very narrow and slightly convoluted. They open 

 into the abdominal cavity by wide funnel-shaped openings, 

 with fimbriated or fringed margins. Posteriorly each passes 

 into a thick-walled uterus (r. ut., /. #/.). The two uteri open 

 separately into a median tube, the vagina (va.}. The vesti- 

 bule (Fig. 287 B, vb.}, or urinogenital canal, is a wide median 

 passage, into which the vagina and the bladder open. On 

 its ventral wall is a small, hard, rod-like body, the clitoris, 

 corresponding to the penis of the male, and composed of 

 two very short corpora cavernosa attached anteriorly to the 

 ischia, with a terminal soft conical glans clitoridis (g. cl.). 

 The vulva, or external opening of the vestibule, is bounded 

 laterally by two prominent folds the labia majora. 



The Rabbit is viviparous. The ovum, which is of 

 relatively small size, after it has escaped from its Graafian 

 follicle, passes into the oviduct, where it becomes fertilised, 

 and reaches the uterus, in which it develops into the foetus, 

 as the intra-uterine embryo is termed. The young animal 

 escapes from the uterus in a condition in which all the
