COTYLOGONIMUS 171 



third of the body were the two testes, somewhat apart, the 

 anterior one roundish, the posterior one distinctly lobate. The 

 oblique and slightly lobate ovary was situated in front of the 

 bifurcation of the Y-shaped excretory bladder, whence the uterus, 

 in convolutions barely spreading beyond the central field, extended 

 to the pore ; the vitellaria in the lateral areas commenced behind 

 the ventral sucker and extended to the testes. The cirrus pouch 

 was lacking ; the eggs were oval, 0*034 0*021 mm. 



A few years previously Lewis and Cunningham found a very 

 similar parasite in the liver of pariah dogs, likewise in Calcutta. 

 It may therefore be assumed that in both cases the same species 

 is dealt with, namely, an Opisthorchis, nearly related to Op. 

 felineus and Op. sinensis. The authors, however, connect their 

 discovery with a species that Cobbold found in the liver of an 

 American fox (Canis fulvus) that died in London, and which 

 Cobbold described as Distoma conjuncium. 



This name is equally applied in literature to McConnell's and to 



the Lewis-Cunningham worm, although there can be no doubt that 



Dist. conjunctum, Cobb., is a distinct although related species. As, 



however, two different species cannot bear the same name, I have 



...given the Indian species the name " noverca"

Small Fasciolidae, the body of which is divided into a narrow, movable, 

 anterior part (neck), and a broader, less movable, posterior portion, which 

 contains the genitaiia. The cuticle closely beset with scale-like spines. 

 The- suckers separated from one another by a space equal to half the 

 length of the body or more ; the pharynx is close behind the oral sucker ; 

 the oesophagus is long, the intestinal branches extend to the posterior 

 border ; the genital pore is placed laterally, and behind the ventral 

 sucker. It is surrounded by a muscular annular elevation (genital promi- 

 nence), which is provided with a wreath of chitinous rodlets, shaped like 

 stags' horns. There is no cirrus pouch. The testes are at the posterior end,
