A single female from the Andamans. Judging from its bold 
coloration, this specimen is immature. In many respects the spe- 
cies resembles Hnhydris curtus, from vhich it may be distinguished 
superficially by the possession of unbroken parietals and distinct 
chin shields. It has six grooved teeth posterior to the large poison 
fangs in each maxilla. Its nearest ally is D. lapimidordes. ;
