oral sucker varies in width from 232/i, to 242/i. The pharynx is im- 

 mediately behind the oral sucker and is broader than long. Its 

 width varies from 281/* to 300/*, its length from 232/x to 242/*. The 

 esophagus is very short. The intestinal branches 

 extend to the posterior extremity of the body. 

 The testes lie in the posterior half of the body, 

 one in front of the other. The posterior testis is 

 slightly lobate, while the anterior testis is nearly 

 round. The ovary is composed of three or four 

 lobules and is about 400/x long. Posterolateral 

 to the ovary is situated the pyriform receptacu- 

 lum seminis. The vitellaria are in the anterior 

 half of the body only and lie almost entirely out- 

 side of the intestinal branches. The right gland 

 is from 2.2 mm. to 2.3 mm. long. The left gland 

 is a little shorter, about 2 mm. to 2.2 mm. long. 

 The uterus is rosette-shaped, and is situated in 

 the anterior half of the body. The excretory 

 canal is a sigmoid lying between the testes and 

 ending just back of the uterine complex. The 

 eggs average 28/* to 32/* long by 15/* to IS/t 

 wide.
