Sub-family (II) PARUTERININAE , Ransom, 1909, 



= Paruterinae, Fuhrmann, 1907. 



vSub-f amily diagnosis : — Hymenolepididae. Scolex usually 

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

 provisionally placed by Ransom in this sub-family) set of repro- 

 ductive 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 mam- 

 mals). 



Type-genus Paruterina, Fuhrmann, igo6. 



Genus Stilesia, Railliet, 1893 



Generic diagnosis: — (?) Paruterininae. Head unarmed, with- 

 out rostellum. Neck present. Segments broader than long, A 

 double set of reproductive organs in each segment, with opposite 

 pore, or with irregularly alternatmg pore, those on one side with 

 the corresponding cirrus pouch, vagina and ovary having been 

 suppressed, both of which conditions may occur in the same 

 stobila. Genital canals pass between the longitudinal excretory 

 vessels and dorsal of the nerve. Dorsal excretory vessel a con- 

 siderable distance mediad from the ventral vessel. Testicles 

 relatively few (six to twelve in each set), in the lateral portions 

 of the segment in the neighbourhood of the longitudinal excretory 

 vessel. Ovary small, globose, between the dorsal and ventral 

 excretor}^ vessel on pore side of segment. Yolk glands not appa- 

 rent. Uterus small, spherical, sac-like, one in each lateral half of 

 the segment between the dorsal and ventral excretory vessels. 

 When the ovary is absent from one side eggs from the opposite 

 side of the segment appear to pass across through the median 

 field, in a manner not understood, and enter the uterus of the 

 side in which the ovary is lacking. Immediately anterior and 

 mediad of each uterus, a para-uterine organ develops, into which 

 the eggs probably pass, Kggs with two envelopes. Adults in 

 mammals (ruminants).
