Two specimens, a male and a young, formed part of a 

 collection of reptiles made by Mr. L. Clarke Webster in the 

 Coolgardie District,in theinteriorof West Australia (400 miles 

 inland of Perth). Mr. Webster's collection contains besides 

 examples of some little-knownspecies : — Diplodactylusciliaris, 

 Tiliqua occipitalis^ Egernia striolata (var.), Egernia depressa, 

 Lygosoma 2)rcepeditum, and a second example of the death- 

 adder described by me a ^qv: years ago as Acanthophis pyrrhus. 

 This example agrees very closely with the type, from Station 

 Point, South Central Australia, and has 141 ventral shields 

 and 53 caudals, of which the last 26 are in pairs.
