Genus CAMPULA Cobbold, 1858 



Synonym. — Brachycladium Looss, 1899, p. 558. 



Gener'w diagnosis. — Campulinae: Body elongated and slightly 

 flattened; posterior end usually more pointed than anterior end. 

 Cuticle completely covered with large, pointed spines. Oral sucker 

 slightly smaller than acetabulum. Intestinal ceca with short median 

 and lateral diverticula. Excretory vesicle tubelike, extending an- 

 teriorly to ovary. Genital pore immediately cephalad of acetabulum ; 

 cirrus pouch short; cirrus unarmed; testes with or without lobes, 

 never dendritic. Ovary entire, pretesticular ; seminal receptacle re- 

 duced; Laurer's canal present. Vitellaria profusely developed, ex- 

 tending anteriorly to level of pharynx. Uterus with few coils. Eggs 

 triangular in cross section. 



Type species. — Gmnpula ohlonga Cobbold, 1858.
