Thi^ new species is represented by two specimens which were 

 captured hy me in July, 1916, on the stone wall of Chionin, a 

 Buddhist temple, in Kyoto, and also at Mt. Hiyei. According to 

 the late Professor Ijima's notes he also obtained a specimen refer- 

 able to this species in the former situation. 



The head presents a semi-lunar shape and is more or less wider 

 than the width of the trunk, from which it is distinctly separated 

 by a neck-like constriction. The frontal margin of the hend in 

 the creeping state gives rise to numerous serrated processes. In 

 the hind parts the sides of the trunk converge backwards to a point- 

 ed extremity. The ventral surface is marked with the slightly 

 raised sole, which is rather less than one-third the width of the 

 body and extends almost throughout the entire length of the body. 

 When fully extended the body measures 35 mm. long by 2 nnn. 

 broad and the head may reach twice tlie width of the body, across 

 the apices. 



The cohjur of tlie dorsal surface is brownish orange mixed 

 with a dark tone, leaving a light coloured, median zone which 

 extends over almost the entire length of the body. Along the 

 mid-dorsal line runs a fine black strips from the head to the 

 posterior extremity. Anteriorly the stripe merges into the general 

 colour of the head, which is much darker than the rest of the 



dorsal surface. Ventrally, the colour is 

 similar to that of the dorsal side, though 

 usually palei-; the surface of the sole is 

 pale yellow, and on each side of it is a 

 diffused ])lack line.
