TiENIOID CESTODES OF NORTH AMERICAN BIRDS. 85 



pores irregularly alternate. Testicles numerous, surround female 

 glands posteriorly and on the sides. Vas deferens coiled, seminal 

 vesicle absent. Uterus breaks down early and the eggs become 

 inclosed singly in egg capsules. Adults in mammals and reptiles. 



Type-species. — OocJioristica tuherculata (Rudolphi, 1819) Ltihe, 

 1898. 



Genus PANCERINAa Fuhrmann, 1^ 



Panceria Sonsino, 1895 (not Andres, 1877, sponge). 



Generic diagnosis. — Dipylidiinse : Scolex unarmed, without rostel- 

 lum. A double set of reproductiv^e organs in each segment. Tes- 

 ticles numerous, in the lateral fields of the segment, absent from the 

 median field. Uteri develop in the lateral fields of the segment but 

 disappear early, the eggs becoming isolated in the parenchyma, 

 situated mostly in the lateral fields, few in the median field. Adults 

 in reptiles. 



Type-species. — Pancerina varanii (Stossich, 1895) = Panceria are- 

 naria Sonsino, 1895. 



Subfaixiily PA.E-TJTEK,I]Sri]Sr^zE; (eiXLended naine). 



"Paruterinse" Fuhrmann, 1907. 



Subfamily diagnosis. — Hj^menolepididse : Scolex usually armed, 

 rarely without rostellum. A single (double in Stilesia, provisionally 

 placed in this subfamily) set of reproductive organs in each segment. 

 Uterus simple or double with a single para-uterine organ or multiple 

 with several para-uterine organs, into which the eggs pass in the final 

 stage of development of the segment. Adults in birds and amphibia 

 (Stilesia in mammals). 



Type-genus. — Paruterina Fuhrmann, 1906. 



Genus PARUTERINA Fuhrmann, 1906. 



Generic diagnosis. — Parutermin-ie : Rostellum simple, armed with 

 a double crown of hooks. Genital pores unilateral or irregularly 

 alternate. Testicles (20 to 30) surrounding the female glands behind 

 and at the sides. In front of the uterus a longitudinally elongated 

 parenchymatous organ develops into which the eggs pass after the 

 gravid segments become separated from the strobila. Adults in 

 birds. 



Type-species. — Paruterina candelahraria (Goeze, 1782) Fuhrmann, 

 1906. 



PARUTERINA CANDELABRARIA (Goeze, 1782) Fuhrmann, 1906.

 WoLFFHUGEL, 1900a, pp. 153-164, figs. 85, 87-96 (Taenia candelahraria). 



Host. — Asio jiammeus. 



aFuhrmann (1899f, p. 627; 1901a, p. 758) refers to this genus by this name, which 

 may well be adopted in view of the fact that Panceria Sonsino, 1895, is a homonym 

 of at least one earlier genus.
