 on Gunong Inas, Perak, by the Skeat Expedition. A local speci- 

 men is in the Selangor Museum. It is also known from Burma 

 and Cochinchina. 



Genus DOLIOPHIS. 



Girard, Proc. Ac. Philad. 1857, p. 182. 



Characters of CaUopJtis, except that the poison-glands, instead 

 of being confined to the temporal region (as in most snakes) 

 extend along each side of the body for about one third of its 

 length, gradually thickening and terminating in front of the heart 

 with club-shaped ends. The presence of this organ may be 

 ascertained without dissection by feeling the thickening and rigidity 

 of the cardiac region in the second third of the body, the heart 

 being shifted further back than in other snakes owing to the 

 extension of the glands.
