Digestive Systeyn. — The mouth-opening is situated at a point 

 somewhat behind the middle of the bod}^ or at about the com- 

 mencement of the posterior third of the body. The pharynx, 

 which is cylindrical in shape, is inserted a short distance in front 

 of the middle of the body; its length is nearly equal to one-fifth the 

 length of the body. 



The unpaired anterior main trunk of the intestine extends to 

 a point in front of the brain and gives rise to 8-12 pairs of lateral 

 branches, which are numerously subdivided before reaching the 

 margin of the body; while the posterior trunks are each provided 

 with l.')-18 outer brandies and al)out as many, but much shorter, 

 inner branches. In })lace of the two posterior trunks, which exist 

 in the ordinary Triclad-type, there' are often two parallel trunks on 

 •each side of the pharyngeal chamber. The accessory trunks either 

 take their origin at the root of the phaiynx, like the two normal 

 posterior trunks, or exist as parallel branches of the latter. 



Excretory Systeîn. — The exact arrangement of the excretory 

 system could not l)e ascertained, it seemed to be in accordance with 

 that previously described by Ude (79). Dorsally and ventrally 

 there exist two main vessels on eacîi side of the body, which 

 extend almost throughout the whole body-length and are connected 

 with one another by means of anastomosis. The main vessels give 

 off at several points numerous ducts which open between the 

 epidermic cells. 



Nervous Sytem. — The nervous s^^tem of this species shows no 

 noteworthy variation from that observed by Uj)e in detail. Each 

 longitudinal nerve trunk passes forward over a well-developed 

 brain mass, those of both sides being connected by a number of 

 commissures. Of all the commissures the foremost is the best de- 

 veloped and traversed by three sets of transverse fibres. From 

 each brain -mass arise five forwardly directed sensory nerves, ex- 

 cluding the optic nerve, as well as some lateral nerves. Posteriorly 

 .the longitudinal trunks proceed, running nearly parallel to each 

 other, to the verv tail, and are connected bv transverse commis-
