only the anterior portion of the trunk variously streaked blotched 

 and dotted with yellow. Tail always yellow beneath. Length 

 of the largest specimen 16 inches ; girth of trunk 1 J inches." 



Inhabits South Kanara, " very common on the top of Kudra 

 Mukh " at 6,000. 



From the character of its tail I have removed this species 

 from Sihybura to Plectrurus. The describer does not describe 

 the postocular, which is probably therefore confluent with 

 the supra-orbital. 



Melanophidium, Gilnther. 



Tail slightly compressed, covered with smooth scales and ter- 

 minating in a very small smooth, slightly upturned horny point. 

 Nasals form a suture behind the rostral. Eye in a single plate. 

 A median groove along the chin.
