330 Memoirs of the Indian Museum. [Vol. VIT, 



Tanqua anomala (v. Linst., 1904). 



Hosts : 



"Mud snake," 



Banded krait (Bungarus fasciatus), 



"Green snake." 

 The specimens from the last-mentioned host were in bad condition, and their 

 determination is questionable. 



Genus Echinocephalus, Molin, 1858. 



Echinocephalus spinosissimus (v. Linst., 1905). 



A few mature, though rather small, specimens occurred in the spiral valve region 

 of the intestine of Trygon (Hypolophus) sephen from the Chilka Lake on the East 

 coast of India. The description of this species by Baylis and Lane (1920) necessarily 

 omitted the measurements of the ova. The average size of the eggs in the present 

 material is 0*05 X 0*0375 mm. The host is a new one. 



Genus Gnathostoma, Owen, 1836. 

 Gnathostoma spinigerum, Owen, 1836. 

 Specimens occurred in a fishing cat {Felis viverrina) and in a leopard (Felis 

 par dus). 



Superfamily TRICHINELLOIDEA, Hall, 1916. 



Family TRICHINELLIDAE, Stiles and Crane, 1910. 

 Subfamily TRICHUEINAE, Ransom, 1911. 

 Genus Trichuris, Roederer, 1761. 

 Trichuris trichiura (L., 1771). 



(Syn. Trichocephalus dispar auctt.) 

 Host: Gibbon (Hylobates, sp.). 



Trichuris suis (Schrank, 1788). 

 (Syn. Trichocephalus crenatus auctt.). 

 Host : Wild pig (Sus bengalensis), near Dinapore, Bihar. 



Trichuris ovis (Abildg., 1795). 



(Syn. Trichocephalus affinis auctt.) 

 Host: "Antelope' — probably the Indian antelope or black buck (Antilope 



cervicapra). 



Genus Capillaria, Zeder, 1800. 



Capillaria columbae (Rud., 1819). 

 The collection contains a few specimens of this species, which were taken from 

 the intestine of a pigeon in company with numbers of Ascaridia columbae. The 

 worm has recently been redescribed by Irwin-Smith (1920) in Australia.
