A large specimen from King George's Sound, in Mr. Macleay's 

 collection, differs from the Tasmanian species above described 

 mainly in having the spines on the carapace all shorter and blunter 

 and the anterior limbs very large, with the hand much dilated, 

 and the fingers meeting only at the tips when closed.
