 Cook Strait to Stewart Island. My specimen came from Auckland (North Island).

Dana himself was inclined to regard this species as a variety of the preceding and in 

 his subsequent great work on the Crustacea of Wilkes' Expedition it seems indeed to be 

 united with H. varius. 



Hab. New Zealand (Bay of Islands).

1) Measured ander the microscope. 



2) As has been noted above (p. 13 note 2), in the explanation of plates of Filhol's work the figure is said to represent Hali- 

 carcinus tridentatus (Jacquinot et Lucas). This discrepancy renders both these species all the more obscure.
