160 THE ANIMAL PARASITES OF MAN 



woman who evacuated the specimen described, after violent pains 

 in the hepatic region. 



According to a written communication by P. Manson to R. 

 Blanchard, two further cases (which species-?) have been observed 

 in North Borneo, the host of one being a Chinaman and the 

 other a Malayan. Nothing is known about the development of 

 either species.

Fasciolidae, with thick oval or broad fusiform bodies, the transverse 

 section of which is almost circular. The cuticle has scale-like spines. 

 The suckers are at a distance of ha.lf the length of the body from each 

 other ; the oesophagus is short, the pharynx almost globular ; the intestinal 

 caeca have no lateral branches, and run in a zig-zag manner to the pos- 

 terior extremity ; the excretory bladder is elongated and reaches to the 

 pharynx ; the genital pore lies laterally near posterior margin of ventral 

 sucker ; no cirrus pouch. The testes are round or ramified, and lie 

 side by side in the posterior half of the body, the ovary, corresponding 

 in form, lies in front of one testis. The vitellaria occupy the whole 

 of the sides and almost reach the median line on the back. Laurer's 

 canal is present ; there is no receptaculum seminis ; the uterus, behind the 

 ventral sucker, forms a prominence. The eggs are fairly large. The para- 

 sites live mostly in pairs within cysts in the lungs of mammals.
