Numerous specimeus of this well-known crab were found in the 

 marshy banks, a little below high-tide mark, in burrows partially filled 

 with water. In the fresh state they are readily recognized and sepa- 

 rated from all other crabs by the color. Carapace, a brilliant purplish 

 blue; carpus and hand, bluish ; proximal upper half of the dactyls of 

 chelipeds^ pink; remainder of fingers, porcelain white; lower portion 

 of chelipeds and carpal tooth, orange-yellow. 



Carapace very convex longitudinally, nearly straight transversely. 

 Front much deflexed, composetl of two lobes, the inner and outer 

 angles alike and evenly rounded. A slight emargination in the coa- 

 lesced tooth. Second tooth semi-lobate ; third and fourth short, pointed, 

 triangular. 



Carpal groove wanting. Fingers evenly dentate. In the larger 

 cheliped there is a slight tooth on the dactyl, and also one on the 

 man us. 



Appendages of male abdomen very much like those of herhstii, with 

 the ohesus type of which it is associated, burrowing in the same bank. 



Length of carapace, 28 millimetres; width, 42.5 millimetres.
