Takydromus sexlineatus Daudiii is sometimes doubtfully attributed 

 to Japan, apparently on Hallowell's authority « who among his Japa- 

 nese specimens distinguished some as T. sexlineatus and others as 

 T. japonicus. Only the former are now m the National Museum (No. 

 7310, five specimens from Simoda), and I can affirm that they are 

 nothing but the regular T. tachydromoides. They have the median 

 dorsal scales rather small and the ventral scales are well carinated; 

 hence probably Hallowell's identification.

 slightly longer than the prefrontals; parietals shorter tlian frontal; 

 interparietal about one-fourth the size of anterior supraocular; 

 occipital small, about the size of third supraocular; eight supralabials, 

 fifth (on right side, sixth on left side) under the eye, its upper, or 

 orbital edge nearlv three times as long as its lower, or labial, edo:e;
