A direct comparison of typical Eumeces elegans from China (which 

 our museum owes to the kmdness of Dr. O. Boettger) with E. latiscu- 

 iatus, from Japan, and E. marginatus, from the Riukius, shows that 

 it is more nearly related to the former than to the latter, the second 

 loreal being as high and short as in the most tjq^ical E. latiscutatus. 

 In fact, the onl}^^ difference I can see consists in the presence of a post- 

 nasal in the latter, in this respect agreeing with E. 'marginatus. The 

 latter I regard as less closely related to the other tw^o than these are 

 among themselves. For further remarks on this subject see above 

 (p. 194).

 other, but with both loreals, upper preocular 

 and anterior supraocular; anterior loreal 

 higher than the posterior, in contact with 

 supranasal, nasal, first and second suprala- 

 bials; posterior loreal pentagonal, as high as 

 wide, in contact with second and third supra- 

 labials(on left side also barely toucliing fourth) ; 

 frontal longer than parietals, longer than its 

 distance from tip of snout, anteriorly a little 

 wider than behind, in contact wdth three 

 supraoculars; four supraoculars, second largest; six or seven super-
