262 PLATTHELMINTHES. 



R. Bl.) perfoliata Goeze, and T. plicata Rud., in the horse ; T. (Moniezia 

 R. ~B>\.) pectinata Goeze, in the hare; T. dispar Rud., in the frog; T. 

 (Ctenotaenia R.) expansa Ini., in the ox. 



There is a special section of Taenias,* in which the genital opening is on the 

 broad surface of the segment : such are T. litterata Batsch. ; T. lineata Goeze, 

 in the intestine of the dog. To another group belong Taenias from the gut of 

 birds, e.g. T. sinuosa Zed,, in the goose and duck; T. temdrostris from 

 Merganser and Anas, both with tailed Cysticercoids in Gammarus. 



* A number of new genera have been recently created for the reception of 

 species formerly united under Taenia: vide A. Railliet, "Notices parasitolo- 

 giques," Bull. Soc. Zool. France, 1892 ; and R. Blanchard, Mem. de la Soc. Zool. 

 dc France, 4, 1891, p. 420.
