NOTES ON SNAKES COLLECTED IN UPPER ASSAJl. 



(•.21 



Dinodon septentrlonalis (^Giintlier). 



I received a small living specimen from Mr. Gore captured at Namsang. * 

 It was a very beautiful little snake with its coal-black ground colour 

 and milky-white cross-bars, resembling very closely the many banded 

 Krait (^Buugarus muUicincUis) for which 1 at first took it. In certain lights the 

 black had a purplish tinge. There were 27 white bars on the body and 17 on 

 the tail. It was a 9 . 'i^"<^ measured 2 feet 1| inches, of which the tail accounted 

 for Otj^ inches. The veutrals and subcaudals were 214+ 81, the former 

 angulate. The anal entire. The scales at a point 2 heads-lengths behind the 

 head were in 17 rows, at midbody 17, and at a point 2 heads-lengths before the 

 anus 13, This last is unusual, the rows at this site being normally 15. The 

 reduction from 17 to 15 caused by a fusion of the 3rd and 4th rows above 

 the ventrals. The eye in life was quite black, but the pupil was subsequently 

 noted to be vertical. 



Zaoojs nigromarg hiatus (^Blyth.) 



I may here mention that an Officer at Kohima in the Naga Hills sent me a 

 coloured picture of a snake caught and killed in his garden on the 21st May. 

 which had excited his admiration and interest. There can be no doubt as to 

 its identity. The body is coloured foliaceous-green with the scales edged black. 

 The head is brown on the snout, merging to green on the occiput. The 

 characteristic black bauds down the tail are also nicely shown. The specimen 

 measured 7 feet 6 inches. 



Zamenis Icorros (Schlegel). 



Thirteen specimens were collected, all from Dibrugarh except one from 

 Sadiya. Of those sexed 4 were ^ ^, 7 9 $ —
