 on the palms of the chelipeds are features in common between Filhol's specimen and mine.

Filhol obtained this species along the coast of the South Inland (New Zealand), from 

 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).

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