HTDROPHOBTJS. 297 



The following species rests only upon Cantor's diagnosis :

 "Light brown; yellowish white beneath. Ventrals 245; sub- 

 caudals 78." 

 Bengal. 



HUEEIAH SANGUIVENTER, Cantor, t. c. p. 52, is also probably a 

 Lycodon. 



" Claret-purple above, with metallic lustre ; blood-coloured 

 beneath. Ventrals 207 ; subcaudals 99, the 14 anterior of which 

 are entire." See GKinther, Sept. B. I. p. 222, fig.

Maxillary teeth 8 to 10, increasing in size posteriorly ; anterior 

 mandibular teeth a little longer than the posterior. Head 

 distinct from neck, much depressed ; eye moderate or rather large,

This East-Indian genus, allied to Lycodon, comprises five species, 

 three of which are described here. The two others are H. snban- 

 nulatus, D. & B. (Nympliopliidium maculatum, Gthr.), from 

 Sumatra and Singapore, and //. muelleri, D. & B., from the 

 Philippines. 



The name Odontomus, Dum. & Bibr. (1854), is preoccupied (Kirby, 1837).
