In life this species is generally some shade of red, purplish red 

 or salmon. "Our specimens are usually reddish salmon, or pink; 

 on the front part of the carapace there is often a red spot. Under 

 surfaces whitish, with some pale brown spots on the abdomen. Chelse 

 pinkish brown, their tips dark brown or nearly black." (C. S. Y.) 



The carapace of an unusually large specimen from Brazil, was 

 16.6"'"^ long, by 26.5™"" broad ; ratio, 1 : 1.6. (Smith.) 



Measurements of Bermuda specimens. 



In all our specimens the right chela is the larger. It is easily dis- 

 tinguished by the small, sharp marginal denticles. 



We found this species rather rare at Bermuda. It lives under 

 stones at low tide and among dead corals on the reefs. It was also 

 in the early collections of J. M. Jones and G. B. Goode (Yale Mus.), 

 and in the collection made by the Bermuda Biological Station, 1903. 



Its range extends from South Carolina and Florida through the 

 West Indies to Colon (Smith), and Rio Janeiro (Dana). Abrolhos Is,,
