Sandy beaches near Valparaiso. 



Length of carapax, 6*4 lines; breadth, 6*9 lines; ratio, 1 : 1'08. 

 The outer antennae are as naked as in the violacea. The carpus and 

 hand are fine granulous. The penult (fifth) joint of the second, third, 

 and fourth pairs of legs is hirsute in tufts, and the fourth joint a little 

 so ; the third joint is much narrower than in the violacea. The colour 

 of the species is dark brownish or bluish black, somewhat lined trans-

PORCELLANA ELONGATA, Edw. 



New Zealand, Bay of Islands. 



Length of carapax, 6*4 lines ; breadth, 5' 8 lines ; ratio, 1 : 09. In 

 our specimens, the tooth on the anterior margin of the carpus near its 

 base is commonly acute, though sometimes obtuse. The outer an- 

 tennae are naked, the hairs being extremely short. The longitudinal 

 depression of the beak is not deep. The fifth joint of the fourth pair 

 of legs is hirsute, and the fourth somewhat so about apex. The third 

 joint has a nearly smooth surface. 



In another specimen, seven and one-fifth lines long, which appears 

 to be of this species, the tooth on the anterior margin of carpus is obso- 

 lescent, and there is only one serrature on the posterior margin near 

 apex. The third joint of the fourth pair of legs has the surface slightly 

 rugulose.
