resembles very closely the figure and description of P. validus 

 Smith from the west coast of Central America, given by Benedict 

 and Rathbun (Proc. U. S. Nat. Mus., XIV., p. 362, 1891). Prob- 

 ably P. hci'bstii and P. validus represent the east and west coast 

 forms of the same species.- 



ip) I ^ , I 9 , under stones Long Bird Island, '98. The $ is 

 22 mm. X 34 mm. As the stones are lifted it is quite possible to 

 overlook the crab, so close is its resemblance to the mud in 

 which it lies concealed. 



' Heilprin, Miers and Ortmann report P. Jicrbstii var. scrrata 

 Saussure ; and J. M. Jones previously reported the same. These 

 were small specimens — probably P. bcniuidcnsis. P. Jicrbstii I 

 consider new to the Islands. 



Distribution : Rhode Island to Brazil ; West Indies ; probably 

 west coast of Central America. 



13. Panopeus bermndensis Benedict and Rathbun. 



Benedict and Rathbun, The Genus Panopeus. Proc. U. S. 

 Nat. Mus., XIV, p. 376, pi. XX, 1891. 



Numerous specimens from Bailey's Bay and Coney Island 

 and dredged at the Flatts, '98. 



The average size of the male is 9.5 mm. long and 13 mm. 

 broad. 



They may be found at low tide under stones in small de- 

 pressions in the sand. They are variously colored, dark, light 

 or mottled, corresponding to their surroundings. The fingers 

 vary considerably ; sometimes quite dark, frequently as light as 

 the palms. I find a large tooth on the dactyl of the larger 

 hand in all but two specimens. 



Collected at Bermuda by G. Brown Goode (B. & R., I. c. 

 supra, p. 377) ; and probably the P. Jicrbstii var. scrratus of the 

 other reports belongs here. 



Distribution : Florida Keys to Brazil ; West Indies. 



*i4. Eurytium limosum (Say). 

 Reported by Miers. 

 Distribution : New York to Brazil ; West Indies.
