THIS also is an Indian species, first described in 

 the work of Dr. Russel. It is about a foot and 

 half in length, and of a moderately deep brown 

 colour, the back being marked throughout the 

 whole length by a broad undulating black band, 

 with a narrow yellowish white margin, while along 

 the sides runs a row of somewhat irregular round- 

 ish black spots : the under part of the animal is of 

 a pearl-colour. The head is hardly broader than 

 the neck, oblong, roundish, depressed, subtrun- 

 cate, and covered with small scales : the teeth are 

 small and numerous, and as there is a marginal 

 row in the upper jaw, there are of course no fangs: 

 the trunk or body is round, of nearly equal thick- 

 ness, and coated with small, orbicular, close-set, 

 carinated scales : the tail is only an inch and half 

 in length, and is thick, tapering to a sharp point : 

 the vent is longitudinal : and the scuta very short, 

 scarce extending from side to side more than a 

 third part of the diameter of the abdomen. 



This snake, Dr. Russel informs us, is said to 

 produce by its bite a slow wasting of the fingers 

 and toes, similar to what happens in some leprous
