Japahira rnitsukurii diifers from J. swinhonis chiefly in ]')roportions 

 and coloration. Thus, the head, and especially the snout, is longer 

 and narrower; the hind legs are somewhat longer, and the tail very 

 much so. As a rule, the scales are somewhat smaller,^ with less con- 

 trast between the extremes, but the nuchal and dorsal crests are 

 better developed, the latter continuous with the caudal, the keels 

 on underside sharper and the scales more pointed. The coloration 



a Dedicated to Prof. Kakichi Mitsukuri, of the Imperial University of Tokyo. 



^ T]nis, as a rule, the nasal is smaller and separated from the snpralatial by a narrow 

 scale, while in /. su'inho7iis they are as often in contact . The percentage is not great 

 enough to make this character available for diagnostic purposes.
