320 A. E. Verrill — Decapod Crustacea of Bermuda. 



It has been taken at Bermuda by nearly all collectors. 



We found it very coraraon on most of the precipitous and rocky 

 shores of Bermuda in 1898, but it was far less common in March and 

 April, 1901. Probably the cold period earlier in the winter and 

 spring of 1901, which was so fatal to the fishes,* also killed off many 

 of the crabs of this and allied species. 



This species is found on all tropical coasts. On the Atlantic coast 

 it extends from Florida to Brazil, On the Pacific side it ranges from 

 Peru to Lower California. West Africa, at many localities. Cape 

 Yerde Islands (Dana, Stimpson). Ascension I. and Fayal (Bene- 

 dict). Young individuals were taken by us on the reefs and 

 serpentine atolls at Bermuda. Miss Rathbun has recorded an 

 instance of a young one taken on the Pacific far from land. Small 

 specimens often occur among barnacles, etc., on the bottoms of vessels. 



Pernambuco, Brazil, New Zealand, Tahiti, Natal, Mauritius (Kings- 

 ley). Hawaiian Is. (Dana). 



Four specimens were taken from the bottom of a vessel recently 

 arrived from Swan Island, W. Indies, at Woods Hole, Mass., July 

 14, 1887, (t. S. I. Smith in MSS.).
