A. E. Verrill — Decapod Crustacea of Bermuda. 407 



(No. 4058) 1901, both in shallow water. The ])arty from the Field 

 Nat. Hist. Mus., 1905, obtained a larger and perfect specimen from 

 off Tuckerstown point. Probably it was taken in a fish seine. 



Very likely it is common in deeper water, on rougli bottoms, 

 among and outside the outer reefs, where it can be taken only in 

 baited fish-traps. It appears to be one of the species that the fisher- 

 men call " coral crabs," probably on account of its red color. 



It is commonly taken, of large size, in the West Indies, on similar 

 rough bottoms, in five to thirty fathoms, in fish-traps. It is sluggish 

 in its motions. 



It ranges from S. Carolina to the Abrolhos Islands, Brazil (Smith). 

 S. Carolina (Gibbes); Florida (Stimpson); Abrolhos Is., 30 fath., 

 and off Cape St. Roque, 20 fath. (M. J. Rathbun).

The only Bermuda record of this species is based on a very 

 young S specimen (No. 3019, see pi. xxiii, fig. 1) taken in April, 

 1898.* It has the carapace only 8.5™™ long by 9"'" broad. 



It agrees closely in spinulation with the larger specimens of 31. 

 his2)idus, but the dorsal spinules appear sharper. All the marginal 

 spinules are simple and acute, with the points turned forward. The 

 basal joint of the antennae has a long, acute, central tooth, with the 

 tips slightly incurved, as in the larger ones, and also a smaller outer 

 acute tooth. The carpus of the chelipeds bears several small tuber- 

 cles ; the merus has one small spine on the inner edge ; others above. 



The carapace is yellowish white, with blotches of bright red ; the 

 two largest spots of red are over the branchial areas ; a median is 

 on the cardiac ai'ea ; a pair is situated farther back ; another small 

 pair is behind the orbits ; and another underneath the orbits ; legs 

 yellowish white, blotched or barred with red ; chelae light red with 

 pale tips. 



Although this young specimen differs from the larger ones of 

 31. hispichis in proportions and general appearance, the details of the 

 spinulation, etc., are the same. It does not agree well with the 

 figures of 31. depressus given by A. M. -Edwards. There are, how- 



* This is the specimen recorded by me in 1900, as M. depressus, on the 

 authority of Miss Eathbun, who had examined it.
