short ducts into the urino-genital canal. There 

 are four or five lohes, the largest of which is an 

 anterior lobe, closely applied to the dorsal wall 

 of the uterus masculinus, and bilobed in front : 

 behind this is a smaller posterior lobe, sometimes 

 divided into two : a pair of still smaller lateral 

 lobes lie in the angle between the vasa deferentia 

 and the uterus masculinus. 



k. Cowper's glands are a pair of glandular bodies, 

 varying greatly in size, and placed on the dor- 

 sal wall of the urino-genital canal, behind the 

 prostate. 



1. The rectum is a white tube, with rather .thick 

 muscular walls, lying dorsal to the urino-genital 

 organs, and close ,to the ventral surface of the 

 sacrum. 



m. The perinseal glands are a pair of elongated glan- 

 dular bodies, dark in colour, and about three- 

 quarters of an inch long. They lie at the sides of 

 the penis, and in the anterior walls of the perinaeal 

 sacs, into which their ducts open. 



n. The rectal glands are a pair of pale yellowish 

 bodies, much larger than the perrnseal glands, and 

 lying along the sides and posterior surface of the 

 last two inches of the rectum. 



SKt wp with scissors the urino-genital canal along its 

 whole length, in the mid-ventral line. 



0. The aperture of the uterus masculinus is a large 



crescentic opening in the dorsal wall of the 



urino-genital canal. 

 p. The verumontanum is a small vascular papilla, 



immediately behind the aperture of the uterus 



masculinus. 

 q^. The apertures of the ducts of the prostatic glands 



are small slit-like openings at the sides of the 



verumontanum.
