large and subtriangular. Thirteen rows of scales: scutae 136, 138; 

 scutellae 27, 28 pairs. Colour shining dull black, brilliant and irides- 

 cent below : minute yellowish-white specks on the sides of the mouth, 

 throat, and along the sides of the body. In spirit the edges of the 

 scales are seen to be of a deep black, imparting a reticulated appear- 

 ance. The larger of two specimens measures 12 in., of which tail 

 2f in. Prom Asam. Mr. Bobinson. 



C. tenuiceps, nobis, n. s. Colour iridescent black above, yellow- 

 ish-white below. Nearly affined to C. longiceps, Cantor, but the 

 head anterior to the eyes much less elongated, and the posterior 

 frontals consequently are about as broad as long : vertical plate 

 elongate-hexangular, broadest anteriorly : head conical, narrow ; the 

 jaws of equal length. Thirteen rows of scales. Scutae 138 ; scu- 

 tellae 37 pairs. Length of specimen 14 in., of which tail 2 in. 

 Prom the vicinity of Darjiling. Capt. ~YV. S. Sherwill. 



The two following species of this genus are remarkable for having 

 the posterior frontals united. 



C. fusca, nobis, n. s. Of an iridescent dull black colour through- 

 out, the ventrals slightly margined paler. Head small, narrow. 

 Vertical plate pentangular with rounded anterior base, the 

 posterior lateral angles so obtuse in some that the plate might then 

 be described as triangular : occipitals very large, elongated. Thirteen 

 rows of scales. Scutse 155-7; scutellaa 30-34 pairs. Length 15 

 in., of which tail 2 in. Young obscurely striated with longitudinal 

 rows of pale dots. Prom Darjiling. Capt. W. S. Sherwill. 



C. OBSCURO-STRIA.TA, nobis, n. s. Much affined to last : the 

 muzzle less obtusely pointed, and the anterior frontals conspicuously 

 smaller. Iridescent brown-black, the under-parts particularly lus- 

 trous ; obscurely streaked throughout with a pale band occupying 

 the adjoining portions of the fourth and fifth rows of scales on each 

 side, a narrow pale line also along the middle of each of the first 

 three rows, and three similar narrow pale lines along the back, all 

 alternating with dusky lines. Thirteen rows of scales. Scutae 153- 

 163 ; scutellae 40 pairs. Length of the larger of two specimens 

 11| in., of which tail 2 in. Prom Eangoon. 



The next has both the anterior and the posterior frontals, respec- 

 tively, united or undivided.
