Verrill, Amer. Nat., Ill, 245. 



Two females of this species was brought by Mr. W. J. Fisher from Mulege 

 Bay, Gulf of California. 



"Everywhere covered, except the dactylus of the right ambulatory leg of 

 of the second pair in the female, and tips of the others in both sexes with a 

 very short and close, clay-colored pubescence, much like a uniform coating of

Found in the pearl oyster, Margaritophora fimbriata. 



A new species of Pontonia (P. margarita, Loekington,) is mentioned by Mr. 

 Fisher as having been taken from Marguritana margaritifera, at Port Escon- 

 dido, Gulf of California, but as Mr. Fisher's collections were almost exclu- 

 sively marine, it is not unlikely that the above mentioned mollusk was the 

 one he meant to indicate.

 From Lithodomus aristatus, Pearl Islands, Panama.

 more curved than the concave internal margin; distal extremity rounded and 

 ciliate on its internal edge, terminal joints ciliate. Chelipeds smooth, cylin- 

 drical, save that the manus is somewhat compressed distally; dactylus short, 

 about half as long as the posterior part of the propodus, and equal in leugth 

 to the propodal finger; both fingers hooked at the end, without teeth on their
