are present sparsely scattered over tlie wliole length of tlie 

 submarginally on the ventral surface. 



The mouth-opening is situated near the 

 middle of the body, leading into the peri- 

 pharyngeal pocket. 



The genital organs were not yet de- 

 veloped in the individual examined. 



Note : — The present species seems to 

 resemble Bipallum venosum previously des- 

 cribed as well as B. glganteum Whitehouse 

 and B. claparedel von Guaff, but may be 

 distinguished from any of them by the dif- 

 ferences in the appearance of the head and 

 the colouration of the body.

A single representative of this new species was captured by 

 Mr. Ykri in .January, 191 (), in Nara. 



The iiead in the preserved state presents a ver^' small, semi- 

 lunar shape and is a gieat deal narrower than the width of the 

 trunk, from which it is only separated by a slight constriction. The 

 trunk, which is nearly oval in cross section, is almost uniformly 

 l>road for the most part of its length and gradually tapers in the 

 hind parts to the rounded posterior extremity. Extending from 

 the base of the head to the posterior extremity is the sole, which is 

 raised into a prominent ridge and less than one-fourth the width of 

 the body. The l)ody measures 50 mm. in length and oö mm. in 

 l>readth. 



The dorsal surface, in spirit, is of a dirty yellowisli colour witli 

 a fairly thick black stripe which medially extends almost through- 

 out the whole length of the body. On the ventral surface the 

 colour is nuich paler than on the dorsal, except for the creeping 

 area which is nearly white.
