A. E. Verrill — Decapod Crustacea of Bermuda. 393 



Perhaps these long slender legs may be spread out on the surface of 

 the sand to imitate annelids and so serve as a lure for small fishes. 

 We had no opportunity to test this proposition. The very young 

 specimens did not show this distinction in the color of the legs, so 

 far as observed. 



Measurements of Bermuda sjjecimens. 



The total expanse of the extended chelae in 4055« was 104™™ ; 

 total length of cheliped, 47™™; extent beyond the edge of the cara- 

 pace, 40™™. 



When recently dried there are small smooth areas on the carapace 

 and legs, especially the last pair, that are lustrous and somewhat 

 iridescent ; most of the under side of body and legs is smooth and 

 shining. 



At Bermuda it is a very common species. We found it abundant 

 in shallow water in April, 1898 and 1901, on the sand}^ bottoms of 

 sheltered coves and inlets, as near Walsingham Bay, Coney Island, 

 Hungry Bay, etc. 



It was also contained in the early collections of J. M. Jones, Dr. 

 F. V. Hamlin, G. B. Goode and others. Most of the more recent 

 collectors have also taken it, but all the specimens that I have seen 

 are small and probably immature, for none bear eggs. It was origi- 

 nally described by Dr. Stimpson from Chai'leston, S. C. and Beaufort, 

 N. C. Its range extends from Cape Hatteras to the Antilles. Fort 

 Macon, N. C. (Dr. Yarrow) ; Bahamas (Rankin) ; Culebra (Miss 

 Rathbun).
