Genus CULCITELLA Fuhrmann, 1906. 



Generic diagnosis. — Paruteriiiinse: Scolex with simple rostellum, 

 armed with a double crown of hooks. Genital pores unilateral or 

 irregularly alternating. Genital canals pass between the longitudi- 

 nal excretory vessels. Testicles numerous, in a group behind the 

 female glands, in some cases also extending forward along the sides of 

 the latter. A transversely elongated parenchymatous mass or para- 

 uterine organ into which, probably, the eggs finally pass, develops 

 in front of the sac-like transversely elongated uterus. On the pore 

 side of the segment the large usually ventral longitudinal excretory 

 vessel is dorsal in position and the narrow usually dorsal vessel 

 ventral, the position being normal on the other side. Adults in birds. 



Type-species. — Culcitella rapacicola Fuhrmann, 1906. 



Genus RHABDOMETRA Kholodkovski, 1906. 



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

 more) in posterior portion of segment, in a group behind and extend- 

 ing forward along the sides of the female glands. Genital canals 

 pass between the longitudinal excretory vessels. Uterus tubular 

 and elongated longitudinally, or globular, occupying the median 

 line of the segment. A para-uterine organ develops in front of the 

 uterus and extends forward nearly to the anterior border of the 

 segment. Adults in birds.
