In life the back of the carapace is closely covered with dark brown, 

 stout hairs, many of them with hooked tips, and in most cases it is 

 more or less concealed by foreign growths, especially sponges (see 

 fig.). Most of the specimens taken in deep water at Dominica I. 

 had the back, and sometimes the legs, covered with an elegantly 

 colored sea anemone ( CalUactis tricolor), so numerous that the edges 

 of their bases were in close contact, but others had sponges attached 

 to the carapace. 



A good male specimen from Egmont Key, W. Florida (No. 97 1, 

 Yale Mus.), has very little foreign growths on the carapace, except 

 a few small red algse. But there is considerable fine sand adhering 

 between the hairs. It comes from a sandy region, and had, perhaps, 

 recently moulted. The long hooked hairs are partly in clusters or 

 large groups.

The total length of a cheliped, of No. 971, is 186"^"'; merus, 74""™; 

 carpus, 25"!'"; chela, SB"'""; rostral horns, 30"^'". 



The old males sometimes become very large, having the body 

 ne'arly si.x inches long and four wide, including the horns and spines, 

 but most of our specimens from Dominica are about two-thirds that 

 size. 



The only Bermuda record is that given by Hurdis, but he could 

 hardly have mistaken such a peculiar and conspicuous species. His 

 specimen was taken in a lobster-pot. 



It ranges from oif Georgia to Bahia, Brazil. Gulf of Mexico and 

 off Yucatan, seventeen stations, 21-30 fathoms (Rathbun). Bahia,
