D.—AUSTRALIA AND THE LARGE ADJACENT ISLANDS. 
The Sunda Islands and the whole of Malaysia are rich in 
poisonous snakes. ‘Those that are found there belong for the most 
part to species that we have already met with in India or the 
Malay Peninsula. We shall therefore not describe them again 
here. 
All those that inhabit Australia are included in the great Family 
CoLUBRID# and the Subfamily HEnapina. There are no VIPERIDÆ ; 
but certain genera of poisonous COLUBRID are peculiar to this 
continent. 
These reptiles have been particularly well studied by Gérard
