28 PARASITES OF MAN 



obtusely rounded posteriorly ; the integument being smooth and 

 unarmed ; the reproductive orifices placed immediately above 

 the ventral sucker ; the testes form two large rounded organs, 

 situated below the uterine rosette, and disposed in the middle 

 line, one in front of the other; the uterine folds occupy the 

 front part of the body ; near the lateral margins there are two 

 large vitelligene glands, one on either side of the intestinal 

 tube ; the excretory organ probably consists of a central trunk 

 with diverging branches, opening below.

Distoma Sinense, Cobbold. The discovery of this species is 

 due to Prof. J. F. P. McConnell, who " on the 9th of Sept., 1874, 

 found a large number of flukes in the liver of a Chinese, ob- 

 structing the bile ducts." The species measures T 7 5 " in length, 

 by j" in breadth, the eggs being ~ 3 " by ^" . Dr McConnell 

 showed in his original memoir that the worm cannot well be 

 confounded with Fasciola hepatica, with Distoma lanceolatum, 

 or with D. conjunctum. In this conclusion he was supported 

 by Dr T. R. Lewis, who examined the specimens with him. 

 In a letter communicated to the ' Lancet/ quoted above, I 

 proposed the nomenclature here given ; but Prof. Leuckart, 

 unaware of this step, afterwards suggested the terms Distomum 

 spatulatum. Later on I received numerous specimens from 

 Calcutta, the examination of which enabled me to confirm the
