in its course the vitelline glands at numerous points. The vitelline 

 glands are -represented h,y 1 »ranching cellular masses, which are 

 distributed in the interspaces between the diverticulae of the intes- 

 tine. The mode of their connexion of the glands with the oviduct 

 is effected by means of the short branches of the latter. In the 

 region of the genital opening the oviduct rises upwards and unites 

 with its fellow of the opposite side, to form the glandular organ. 

 The oviduct is lined with a nonciliated epithelium, external to which 

 comes a feeble niuscular layer of circular fibi-es. 



Tlie glandular organ, which is supplied with numerous uni- 

 cellular glands, opens into the posterior outbulging of the vestibulum 

 from above. It shows a definite wall consisting of a single layer of 

 columnar epithelial cells and a thick muscular coating.

A single representative of this new species was obtained by 

 Professor Watasé, Dr. Hôzawa and the late Mr. Yasuda in May, 

 1911, near Taihoku in Formosa. 



The head in the preserved state presents a semi-lunar outline 

 with a recurrent lappet on either side, whicl) curves so far inwards 

 as to meet the sides of the neck. The trunk is almost uniformly 

 broad for the greater part of its length, though it gradually tapers 

 off in the hind parts towards the bluntly pointed postei'ior ex- 

 tremity. From the base of the head to the posterior body end, in 

 the mid-ventral line, is the sole, forming a slightly raised ridge and 

 not a great deal wider than one-fifth the breadth of the body. The 

 specimen measures about 45 mm. long by 6 mm. broad. 



Dorsally, the body, in spirit, is of a unifoim dark reddish 

 brown colour, which on the head gets more or less light towards 

 the frontal margin. Ventrally, the colour is nearly similar to that 

 of the dorsal side, except for the surface of the sole which is pnle. 



Numerous eye-spots surround the entire fringe of tlie head 

 and are continued round to the sides oF the neck whei'e they are 

 more ventral than dor.-al forming a crowded patch. Further, tliey
