Siabfanaily .^ISTOFLOCEFH^^LIlSr^C Blancliard, T891. 



Suhfamily diagnosis. — Anoplocephalidse : Uterus persistent and 

 tubular, sac-like, branched or reticular. Adults in mammals and 

 birds. 



Type-genus. — Anoplocephala E. Blanchard, 1848. 



Genus TRIPLOT.^NIA Boas, 1902. 



Generic diagnosis. — Anoplocephalinge : Segmentation of strobila not 

 apparent externally. One ovary, yolk gland, and testicle in each 

 lateral half " of the segment, near the border in the neighborhood of 

 the longitudinal excretory vessels and nerve. One vagina in each 

 lateral half of the segment. Four to five cirrus pouches in each 

 lateral half of the segment. Uterus, one in each lateral half of the 

 gravid segment, sac-like, transversely elongated. Egg with well- 

 developed pyriform apparatus, the horns of which are prolonged in 

 two coiled filaments. Adults in marsupials. 



Type-species, — Triplotmnia mirahilis Boas, 1902. 



Genus ANOPLOCEPHALA E. Blanchard, 1848. 

 Plagiotcenia Peters, 1871 (type, Tcenia gigantea Peters, 1857). 



Generic diagnosis. — Anoplocephalinse : Segments generally much 

 broader than long, occasionally longer than broad. A single set of 

 reproductive organs in each segment. Genital pores unilateral or 

 irregularly alternate. Genital canals pass on the dorsal side of the 

 longitudinal excretory vessels; and nerve. Testicles and female glands 

 in the median field ; female glands toAvard the pore side of the seg- 

 ment, testicles toward the opposite side. Uterus a transversely elon- 

 gated sac with pocket-like appendages, anteriorly and posteriorly. 

 Eggs with well-developed pyriform apparatus. Adults in mammals. 



Type-species. — Anoplocephala perfoliata (Goeze, 1782) E. Blanch- 

 ard, 1848. 



Genus BERTIELLA Stiles and Hassall, 1902. 



Bertia Blanchard, 1891 (homonym of Bertia Ancey, 1888, mollusk). 



Generic diagnosis. — Anoplocephalinse : Segments always broader 

 than long. A single set of reproductive organs in each segment. 

 Genital pores regularly or irregularly alternate. Genital canals pass 

 dorsal of longitudinal excretorj^ vessels and usually dorsal of nerve. 



« The specimens on which the species Trlitlotcenia miraMlis was based each 

 consisted of a head to which apparently two strobilie were attached. Janicki 

 (1906), however, has shown that this condition is probably teratological, and 

 that the double strobila represents the separated lateral halves of a single 

 strobila.
