ventral sucker. It is pyriform in shape and discbarges posteriorly 

 by a short thick-walled canal 016 mm. long in the mid-dorsal 

 line, 06 mm. in front of the lip of the ventral sucker, and 0*9 mm. 

 behind Laurer's canal. 



The genitalia discharge by a small common pore at the level of 

 the bifurcation of the gut. The arrangements of the various 

 structures in this region are well shown in text-fig. 35.. 



The testes are two large round or ovoid bodies - 45 mm. by 

 0*6 mm. in diameter, lying one in front of the other, the posterior 

 resting upon the ovary and shell-gland. 



The ovary is elongated dorso-ventrally, being wedged in between 

 the posterior testis and the fundus of the excretory vesicle. It 

 measures about 025 mm. by O09 mm. 



The shell-glands form a well-defined mass lying slightly to one 

 side of the ovary. From them Laurer's canal can be traced 

 forwards and to the dorsal surface to discharge there at about 

 the level of the centre of the posterior testis and in the middle 

 line 0*9 mm. in front of the excretory pore.
