NOTES ON SNAKES COLLECTED IN DPP Eh' ASSAM. 84:^ 



the tail being li inches. The ventrals and suhcuudals were 241 + 46. 

 The second was a ^. The ventrals and subcandals were 219 + 30. 

 The third very young, with 223 ventrals, and 31 subcandals. 



The type was sent to me alive. It exhibited a distaste to being 

 handled but could not be provoked to bite an object ; when taken by 

 the neck a good large drop of poison collected below the rostral 

 through which the tongue was protruded. It flattened itself posterior- 

 ly under excitement. 



Amblycephalid^, 

 Ainhlycephalus monticola (Cantor). 



Two specimens were collected. One captured in Dibrugarh, and 

 the other at Jaipur. It is essentially a hill snake, so that it is re- 

 markable to tind it in the plains as far distant from the hills as 

 Dibrugarh. The ventrals and subcaudals were 188 + 85, and 

 lyu + ?. There is nothing special to remark upon, except that the 

 secretion of the anal glands is custard-like in colour and consistency. 



VlPERID^. 



Lachesis gramineus (iShawj. 

 The green pit-viper is not very common in the plains of Assam 

 1 got 7 specimens in all. One was from Jaipur, one from North 

 Lakhimpur (Joyhing), and the rest from around Dibrugarh. One 

 specimen was greenish-yellow with a mustard-yellow flank line. 

 In the Joyhing specimen the flank line was chocolate and white as 

 noted in specimens from the Khasi Hills. 



One encountered in November was found lying on a low bush in 

 jungle. It refused to bestir itself, though probed and hustled with a 

 stick. It finally wreathed itself round the stick, and was removed 

 from the bush, but offered no malice.
