chelipeds has six sharp spines on its anterior edge with a close fringe 

 of long red hairs above, and a smaller one below them ; it lias also 

 a sharp distal spine on the posterior side. There are three sharp 

 dorsal spines on the inanns : the proximal at the joint, one sharp 

 and curved toward the distal end, and a smaller one at the extreme 

 end. Carpal spines two, very sharp. Nearly all the spines are red 

 at base with a pale middle band and darker tip. The dactyl us has a 

 dorsal fringe of red hairs. The general color of preserved speci- 

 mens is pale orange yellow ; three faint reddish bands on the legs

This species has rarely been taken in the Bermudas. An adult 

 female was obtained by Mr. G. B. Goode in 1876 (coll. Wesleyan 

 Univ.). It probably lives in rather deep water. Large specimens 

 collected at Dominica I., Antilles, in 1906, were taken in fish-nets, in 

 shallow water (A. H. Verrill, Yale Mus.). 



Its range extends from North Carolina through the West Indies 

 to Brazil. Martinique and Brazil (Edw.) ; Porto Rico (Rathbun).

This species is easily recognized by the smooth silvery or iridescent 

 area on the outer surface of the chelae. The four frontal teeth are 

 narrow, prominent, and subacute ; the inner orbital tooth is simple, 

 triangular and acute. The posterior lateral tooth is larger than the 

 others, bnt not very long ; it is sharp and curves forward ; all the 

 other teeth curve forward. The carapace and legs are pubescent
