 Ejopa, and a beautiful new Gecko congeneric, with that described 

 from the mountainous interior of the Tenasserim provinces, in J". A. 8.

3S]aultinus (?) easciolatus, nobis, n. s. Tail proportionally long- 

 er and more slender than in N. (?) variegatus, nobis, I. c. ■ but 

 the larger of two specimens evidently not full-grown. Head very 

 similar to that of the other ; but the dark band behind the eye bend- 

 ing abruptly to meet its opposite on the occiput ; this is followed by 

 23 other blackish cross-bands, continued to the end of the tail, those 

 of the body being edged and set off posteriorly with whitish ; a series 

 of broad sub-haxagonal plates in both species beginning near the vent' 

 and continued to the end of the tail underneath. Abdominal scales 

 proportionally smaller than in the other, and no group of conspi- 

 cuously larger scales anterior to the vent. The sub-caudal scales are 

 also much smaller than in the other. Larger specimen 4| in., of 

 which tail 2f in. Both species are remarkable for the beauty of their 

 markings. 



Of Snakes, Corcotella Kttssellii, (Daud.), Coluber mucosus, 

 (L.), Dipsas trigonata, Schlegel, Vipera Bussellii, (Shaw), and 

 two species which appear to be new : — 



Dipsas multieasciata, nobis, n. s. Form typical ; the muzzle 

 shorter and rounder than in D. trigonata : the same whitish spots 

 along the ridge of the back as in that species, but somewhat indis- 

 tinctly defined ; and narrow black transverse bands on the sides, num- 

 bering as many as 72 from neck to vent, beyond which they are 

 broken into spots : throat dull white ; the abdominal surface densely 

 speckled throughout with triangular black spots, which are more or 

 less continued into lines. Length of specimen (evidently young) 

 14^ in., of which tail 3 in. 



For the other I must constitute a genus :— 



Platyceps, n. g. Like Coluber (Cortthodon, D. B.), but with 

 exceedingly flat head, and tail only about a sixth of the total length. 



Pl. semieasciatus, nobis, n. s. Colour olive-grey above, white 

 below ; the posterior two-fifths without markings, and the nuchal 

 region marked with broad transverse black bands, having lateral 

 black spots alternating on either side. These gradually become
