NOTES ON i^NAKES FROM DARJEELiNG. U7 



to record it in the other. I found the ventralsus low as 193. und the suhcaudals 



as high as 109. 



Coluber rad/'a'us. — Schlegel, 



(j examples, all from Pashok. 



Dcudrophis picius. — Gmeliu . 



I obtained specimens which I asaign to this species," three from Pashok, the 

 rest from Pashok or Tindharia. The scales were Ifj anteriorly and in mid- 

 body, and ll'or 9 at a point two heads-lengths before the anus. The ventrals 

 and subcaudals were '203 + 140, 205 + 14-^, 191 + 145? 'J06 + V and 204 + V 

 and 202 + 132, respectively. The vertebrals in midbody were as broad as lonj, 

 or rather broader. The anal was divided in all. 



One specimen I saw in St. Joseph's College collection which 1 include here 

 l)ro tem belongs, I consider, to a species as yet not described. In this the anal 

 was entire, the ventrals and subcaudals 187 + 151, and the scale rows 15 

 anteriorly and in midbody, 9 bebind at a point two heads-lengths before the 

 anus. The vertebrals at midbody were a shade longer than broad. This speci- 

 men appears to me to agree in every way with a large series of specimens I 

 have collected in Assam and two others I have had from Jalpaiguri in all of 

 which the anal is enth-e. This last is a noteworthy feature for no other of the 

 species of Dendrophis and D^nclrelaphis hitherto described is similarly distin- 

 <mished. In a future paper on the snakes of Assam I intend to refer to it as 

 new .species under the title proarchos. 



Dendrelaphis tridrh. — Daudiu. 



Six .specimens which I think there can be no doubt are of this speciesf were 

 received, two from Tindharia, the rest from Pashok. Another similar specimen 

 1 found in the Darjeeling Museum. In these the costals anteriorly and in 

 midbody were 15, at a point two heads-lengths before the anus 9 in ^,1 in $. 

 The vertebrals in midbody were about 5 to f as broad as long, and the ventrals 

 and subcaudals noted were 190+132, 191 + ;45,and 19'2 + lbl, respectively. The 

 anal was divided in all. This species and the last are in general appearance, 

 and the details of their lepidosis extremely alike. The differences I see 

 between them are as follows :. — In irhtr/s there is a small light interparietal 

 spot, and a light vertebral stripe anteriorly. The 2nd, 3rd and 4tli supra- 

 labials (the 1st also sometimes) have narrow black posterior margins- There 

 is a short, nan'ow rather indistinct postocular stripe. There are black inter- 

 rupted oblique stripes on the sides of the forebody arranged in pair.s. Two 

 supralabials only, vi~., the 5th and Gth touch the eye. The vertebral row 

 develops gradually on the nape, and in midbody the length of each shield 

 exceeds the breadth. The maxillary teeth numbei IG to 19, and the most pos- 

 terior are rather .smaller than the preceding. The nasal bones are of a distinct 

 shape. 



In picius there is no interparietal light spot, no vertebral light stripe anter- 



* I have prepared 3 skulls from these. 



t I have prepared 5 skulls from these, and all are undoubtedly typical of this Genus.
