unpaired branch being 350/* long. Uteri very long, their course 

 greatly twisted and turned within the distended body; the initial 

 region of uterus, where it connects with the oviduct, enlarged to form 

 an enormous seminal receptacle (fig. 403c?), measuring 660/* long by 

 215/* wide. Diameter of oviduct only 35/*; oviducts and ovaries 8 

 mm. long. Eggs 28 to 30/* long by 15 to 18/* wide, with thick, smooth 

 shells and containing well-developed embryo when deposited. 



Life history. — Probably similar in a general way to that of T. 

 fissispina (p. 343). 



Distribution. — Africa (Algeria) and Asia (Russian Turkestan 

 (Lac Kulkainar)).

/Synonym. — T etrameres micropenis Travassos, 19156, part. 



Hosts. — Cancroma cochlearia; secondary : Unknown, probably sim- 

 ilar in a general way to that of T. fissispina (p. 343). 



Location. — Proventriculus. 



Morphology. — T etrameres (p. 334). 



Male unknown. 



Female 3 to 4 mm. long by 1.5 to 2 mm. wide. Body red color, 

 with characteristic shape. Buccal capsule barrel-shaped, 24 to 28/* 

 in height, 14 to 16/* in maximum width ; pharynx 190/* long ; esopha- 

 gus slightly claviform, 990/* long; nerve ring 140/* from anterior end 

 of body. Ovejector (fig. 404) very long and muscular and with a 

 vestibule or proximal portion inserted in the terminal portion at an 

 angle, measuring 1.9 mm. long, 120/* maximum width and 50/* mini- 

 mum width at the distal portion. (The length given is evidently the 

 total length of the ovejector, although Travassos does not make this 

 clear.) Eggs ellipsoidal, slightly flattened on the sides, 42 to 49/* 

 long by 21/* wide.
