specimens (Nos. 65461-6) collected by Rev. D. C. Graham near 

 Mount Wa, Szechwan. The largest is as large as the type, even more 

 brightly colored and with a much higher and better developed 

 nuchal crest, which in the original description of the type is char- 

 acterized as "very feeble."

Diagnosis. — All scales keeled; anterior superciliaries not enlarged 

 into horn-like appendages; supralabials eight; flanks with numer- 

 ous large scales equal to the largest on the back. 



Description of type. — Adult: Eostral low, about four times as 

 wide as high, separated from nasal by one scale; nostril circular, 

 with a swollen rim, in the posterior part of a rather large, oblong 

 scale which is situated below the rostral canthus and in contact with 

 first supralabial; canthus rostralis very sharp, covered with small 

 angular scales forming a ridge continuous with a high superciliary 

 crest, the last two scales of which are enlarged and angidarW com- 

 pressed, above and behind center of eye; top of head, including supra- 

 oculars, covered with unicarinate, more or less wrinkled scale of vary- 

 ing size; snout and interorbital space deeply concave, the later cov- 

 ered with one or two scales between the supraorbital semicircles 

 which end in one or two large pointed, keeled, and wrinkled 

 tubercles back of the eye, separated from the last large superciliary 

 by two or three minute scales forming a gap in the superciliary 

 crest; on either side of the small occipital a larger polj'gonal shield 

 with a high central ribbed tubercle, which with the postorbital 

 supraocular tubercle form a nearly continuous transverse ridge; 

 temples covered with polygonal, tuberculated scales, one group of 

 large tubercles on the postocular semicircle and the other above the 

 tympanic cavity which is covered with minute scales; eight narrow, 

 elongated upper labials and seven lower ones; dorsal surface cov- 

 ered with small, unicarinate scales intermixed with larger scales and 

 tubercles; a low median crest of about six enlarged, compressed, 

 keeled scales on anterior part of upper neck, the third from the 

 occiput being the highest; on either side several groups of enlarged 

 scales and tubercles; no median dorsal or caudal series of enlarged 

 scales; from the shoulders backward a median dorsal zone of small, 

 but fairly imiformly sized, narrow, sharply keeled, imbricate scales,
