290 THE RABBIT 



Carefully remove the pelvic symphysis by cutting through the bones on 

 either side of the middle line, and note the following : — 



(1) The urino-genital canal or urethra, which is a continuation backwards 



of the neck of the urinary bladder. It is situated below the rectum 

 and above the pelvic symphysis, behind which it traverses the penis. 



(2) The penis, which is traversed by the terminal portion of the urethra. 



(3) The uterus masculinus, a sac lying about half-way along and above the 



bladder and opening into the urethra. 



(4) The terminal portions of the vasa deferentia, which together pass back- 



wards above the neck of the bladder, between it and the uterus 

 masculinus, and open separately into the ventral wall of the uterus 

 masculinus, just before its opening into the dorsql wall of the urethra. 

 (5.) The prostate gland, which is on the walls of the uterus masculinus, at 

 the commencement of the urethra and the ends of the vasa deferentia. 



(6) Cowper's glands, a pair of small ovoid glands, lying just behind the 



prostate, close to the side of the urethra. 



(7) The rectal glands, a pair of brown bodies about one inch in length, 



situated on either side of the last two inches of the rectum. 



(8) The perineal glands, a pair of glands which are situated on either side of 



the penis. Their ducts open on the perineal patches at the sides of 

 the anus. 



Slit open the urethra, also the urinary bladder, and note : 



(1) The openings of the ureters on the dorsal wall of the bladder. 



(2) The opening of the uterus masculinus on the dorsal wall of the urethra. 



(3) The openings of the prostate ducts (usually four in number) into the 



urethra.

(b) The Female. 



Remove the pelvic symphysis, as in the male, and iiote : 



(1) The ovaries, a pair of ovoid bodies on the dorsal wall of the abdomen 



and behind the kidneys. 



(2) The two oviducts (Miillerian ducts). Each consists of three distinct 



portions, namely, (3), (4) and (5) undernoted. 



(3) The narrow Fallopian tubes, continuous with the uteri. Their wide 



funnel-like openings are close to the ovaries. 

 ^4) The uteri opening separately into the vagina. 



(5) The vagina a wide median tube formed by the union of the vaginal 



portions of the oviducts. It unites with the neck of the bladder at 

 the beginning of the vestibule. 



(6) The vestibule or urino-genital canal, which opens externally at the vulva. 



(7) The clitoris, corresponding to the penis of the male and situated in the 



vestibule just inside its outer opening. 



(8) Cowper's glands (reduced, sometimes absent), on the dorsal wall of the 



vestibule. 



(9) The perineal and rectal glands, as in the male.
