16 BAKBOUR AND DUNN — CHINESE JAPALURAS [^vlf vil ' 



mens are provisionally considered topotypes. One of the new 

 species described below was found also by Andrews and Heller 

 on the Snow Mountains near Lichiangfu, described in chapter 

 XII of Andrews' 'Camps and Trails in China' (D. Appleton 

 and Co., N. Y., 1918). 



The new foim may be called : 



Japalura flaviceps sp, nov. 



Japahira yunnancnsis Boulenger {nee Anderson), Cat. Liz. B. M., I, 

 1885, p. 310. 



Type, an adult male, M. C. Z., no. 12,469, from among cacti along the 

 sandy shores of the Tung River in western Szechuan; W. R. Zappey, col- 

 lector, 7, February, 1908. Paratypes: four other examples, also in M. C. Z., 

 having the same data as the type, and also three from the Snow Moun- 

 tains near Lichiangfu in northern Yunnan, not far from the Szechuan 

 frontier (A. M. N. H. coll.). 



Description. — Top of head covered with rugose scales of unequal size; 

 on the snout a median series of four distinctly enlarged almost conical scales 

 forming a ridge, and followed by two irregular series of enlarged scales ex- 

 tending almost to the posterior border of the orbit; these two series are 

 separated by fom* or five scales which are themselves larger than the other 

 upper head shields; a group of distinctly enlarged shields on the occipital 

 region. Rostral broad and low, wider and lower than the mental ; canthus 

 rostralis moderately defined and continuous with the superciliaries ; nostril 

 in a large oval shield separated from the labials by generally two but some- 

 '*■! >.-» times a single s^jjes of smaljjscales, and from the rostral by a group of small 

 "' scales usually three in nmnber ; upper labials nine or ten, seventh below the 

 middle of the eye ; orbit separated from upper labials by four (rarely three) 

 rows of small keeled scales; lower labials eleven; an ill-defined series of 

 five enlarged scales extending from the posterior border of the orbit to 

 above the tympanic region ; a few elongated, almost spinelike scales above 

 the tympanum ; nuchal crest composed of about nine or ten enlarged den- 

 ticulate scales, but slightly larger than and continuous with the feebly 

 developed dorsal crest. 



A well-developed fold anterior to insertion of fore limb ; a large area about 

 the insertion of the fore limb covered with very small, keeled and slightly 

 imbricate scales, at first sight resembling granules ; scales of back and sides 

 all imbricate, strongly keeled and varying greatly in size ; the largest scales 

 tend slightly more toward forming longitudinal series than groups trans- 

 versely arranged. Scales of throat and belly subequal in size, strongly 

 keeled, and slightly mucronate; the hind limb, being extended forward,
