Dredged in Port Curtis in 7 fathoms and off Mast Head Island 

 in 17 fathoms (common). 



Carapace broad. The striae on the interior half are broken up 

 into short rounded scales behind which there are four longer and 

 complete ones; all have a thin fringe of short setae interspersed 

 with longer hairs. The carapace is laterally armed with 6-7 

 spines, of which there is also a pair on the gastric region. 



The rostrum is very broad and long, medially grooved and 

 clothed with scattered setae. It is armed with a median and 

 three lateral spines, all of which are very acute. 



The chelipeds are short and stout, armed with a few spines 

 and thickly beset with very long hairs; the setose scales are 

 obscured and even absent in parts. In old males the left cheliped 

 is much enlarged, and is rather more than twice as long as the 

 carapace, the hand being as long as all the other joints and very 

 broad. The dactylus is nearly equal to the palm in length and 

 much longer than the carpus, which almost equals the rostrum. 

 Both fingers have a prominent tooth near their base. The smaller 

 hand and those of young males and females have similar propor- 

 tions, but are without teeth on the fingers. 



The ambulatory legs are armed normally, scaly and clothed 

 with very long hairs. 



The ischium of the external maxillipeds bears a spine on its 

 inner distal margin; the outer, though finely produced, is obtuse.
