PI. XX VI. Moiilli small, at the plane of the hinder end of the 

 anterior sucker«. Oesophajm wanting. Intestinal tranlcs witli nu- 

 merous lateral branches, terminating at the front end of the posterior 

 sucker, widely separated from each other. Common (jenital opening near 

 the left lateral margin of the body, a little in front of the hinder 

 end of the anterior sucker; leading into a deep genital atrium, in 

 which lies tlie club-shaped penis with its smaller end directed out- 

 wards. Ovanj spherical, comparatively small, in the median line, 

 at the end of the anterior third of the whole body. The omluct 

 arises at the anterior end of the ovary on the ventral side, and thence 

 proceeds at first forwards, then turns backwards, and then again 

 proceeds forwards, undergoing more or less convolutions on the way, 

 and is finally continued int(3 the ootijp, which o[>ens into the genital 

 atrium l)y means of a sliort duct, the uterus ((/. fig. G, 1^1. XXVI). 

 ViteUarinni extending from tlie level of the front end of the pharynx 

 to the front end of the posterior sucker; the lobes of the two sides 

 intermingled with each other behind the testes. Vaireil yolh-ducts 

 directed transversely to the long axis of the body, that of the right 

 side longer than its fellow of the opposite side; the two therefore unit- 

 ing with each other on the left side of tlie ovary and there forming a 

 ca[)acious, globular [loîk-resercoir, from which a short niipnired i/olk-diict 

 leads into the oviduct. Vaginal o^^(7////^ on the left side of the body, 

 about midway between the common genital opening and the fnnit 

 end of the testes, surrounded by a mass of compact connective tissue. 

 Testes large, ellipsoidal, paired, just Ijehind the (jvary. A single vas 

 cffcrens arising from each testis, and uniting just in front of the testis 

 of the left side. The ras tief evens thence proceeds for^vards with nu- 

 merous complicated convolutions as represented in fig. (!, PI. XX \' I, 

 and traversing the whole length of the penis finally o})ens at its apex.
