I do not know this species. Size alone is enough to separate it from 
all other Australian members of the genus. It is recorded from the 
Clarence River and Parramatta (Castelnau) and from Wiseman’s 
Ferry on the Hawkesbury River (Sloane). All these localities are in 
New South Wales.

Sloane has determined the synonomy given above. Macleay’s speci- 
men (s) were from Gayndah, South Queensland; Putzeys’ (types of 
basalis) , from “Queensland”. I have the species from Kuranda, 
Longlands Gap, and Mt. Fisher (all on the Atherton Tableland in 
North Queensland), and from rain forest north of Dunoon in north- 
ern New South Wales.

This is a nearly cosmopolitan species, carried by man, but it occurs 
also in natural habitats. I took a series at Lockerbie, on the tip of
