The dorsal coloration is an even moderately light brown 

 covering a deeper black pigment. The ventral surface is slightly 

 darker except for the very prominent ambulacral surface, which is 

 white with a fairly dark median line, and which extends from one 

 extremity to the other. The eyes could not be distinguished with 

 certainty, though on one side there is a somewhat paler circular 

 patch in the middle of which one of a pair of eyes may be situated.

 This beautiful planarian is found at Kurseong in the Eastern 

 Himalayas and Cherrapungi in Assam ; the measurements of 

 the larger specimen are as follows : — 



Length of the body . . . . 90 mm. 



Breadth of the body . . . 4-5 mm. 



Breadth of the head lobe . . 3 mm. 



Breadth of the ambulacral surface . . i mm. 

 Position of the mouth from anterior 



end . . • . • • 45 mm. 



Position of genital aperture from an- 

 terior end . . . . • • 54 mm. 



The upper surface is flat while the lower is slightly arched ; 

 the head is flat and small being only a little wider than the ' neck ' 

 and narrower than the greater part of the trunk, the body tapers 

 gradually towards the posterior end. Judging from the wrinkling 

 of the body in the preseved animal, it would appear capable 

 of considerably greater extension in Hfe. 



The colour pattern on the upper side of the trunk consists of 

 three longitudinal jet black Hues, one median, and a pair of 

 laterals, at the extreme edge of the body^ on a ground colour 

 which differs in the two specimens, in one a creamish 3^ellow and 

 in the other chestnut brown; at the pharyngeal region the median 

 line widens to double its ordinary width, and a slight thickening 

 also occurs over the genital region. The lateral lines, narrower 

 than the median, cease at the ' neck,' while the median one expands 

 into a knob-like termination on the head. The whole of the upper 

 side of the head has a deeper shade than the rest of the body
