154 TAPEWORMS OF HARES AND RAEJUTS STILES. VOL.XIX. 



Dorsal canal dorsal to lateral of ventral canal. Genital canals pass 

 dorsally of longitudinal canals and nerves. 



Host. Horse (Equus caballus). 



This diagnosis is based in part upon the anatomical discussion of 

 this worm by Zschokke, 1 in 1888.

Diagnosis. Anoplocephala transversaria (Krabbe, 1879), E. Blanch- 

 ard, 1891 : Strobila attains 10 to 10 cm. in length by G to 8 mm. 2 in 

 breadth, and is composed of 200 to 300 segments. Head distinct, 0.6 

 to 0.8 mm. broad by 0.6 mm. long, suckers powerful and prominent; 

 posterior lobes absent; neck absent. Genital pores unilateral at about 

 the middle of the margin'. Male organs : 60 to 80 testicles to each seg- 

 ment, confined to the aporose portion of the median field; cirrus-pouch 

 large. Female organs: Yulva ventral of cirrus-pouch; receptaculum 

 seminis elongate; ovary in pore-side portion of median field; uterus 

 transverse, with pouches. Dorsal canal lateral of ventral canal. Gen- 

 ital canals pass the longitudinal canals and nerves dorsally. Ova with 

 well-developed pyriforni body. 



Host. Arctomys, sp. ; in Turkestan by Fedschenko; 



Diagnosis is based on Zschokke's anatomical discussion in 1888. 3 



Genus ANDRYA, Railliet, 1893.

 Tcenia rhopalocephala, Riehm, 1881. 



Provisional diagnosis. Anoplocephaliua3 with segments broader than 

 long, or as long as broad. One set each of male and female organs to 

 each segment; genital pores irregularly alternate with marked ten- 

 dency to unilateral ity; female glands in median field on pore side of 

 median line; uterus appears as a network with peripheral dichotoinous 

 branches and afterwards assumes a more saccular form; testicles 

 confined to median field; a distinct round or elongate pedunculated 

 prostatic gland near ventral canal on pore side of median field; genital 

 canals pass dorsally of ventral (and ? dorsal) canal and nerve. Dorsal 

 canal dorsal to dorso ( 1 lateral ) of ventral canal. Calcareous corpus- 

 cles develop in distal portion of strobila. Egg with well developed 

 pyriform body, the horns of which are rather short. Hosts: Eodents. 



Type. Andrya rhopalocephala (Riehm, 1881), Stiles, 1895.

2 There is evidently a typographical error in Zschokke's figures, for he gives the 

 breadth of the mature segments at 0.6 to 0.8 mm., yet states on the same page that 

 the proglottids are 0.5 mm. long, and twelve times as broad as long.
