'] BARBOUR AND DUNN — CHINESE JAPALURAS 19 



This species ranges distinctly east of the one previously de- 

 scribed. 



This form approaches yunnanensis in having more uniform 

 scales on the top of the head than does fiaviceps. It differs, 

 however, from both species in the much more homogeneous 

 squamation of the back and sides, and in the different arrange- 

 ment of the scales about the nostril and between the eye and 

 supralabials, as well as in having a wholly different type of 

 coloration. 



In the large series of yunnanensis examined, the dark stripe 

 from the eye to the angle of the mouth is a very conspicuous 

 feature; also the spines of the nuchal crest are conspicuously 

 elongated; in contradistinction to the two previously described 

 species the head is flat, or somewhat concave, and is covered 

 with rather homogeneous fiat scales, more irregularly striate 

 than strongly rugose as in the other two forms; also, as will be 

 recalled, the coloration of yumianensis, in the adults especially, 

 consists of conspicuous cross-bands, as figured by Anderson.
