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



The left chelipeds and second ambulatory leg are covered with fan- 

 shaped groups of plumose hairs, mostly dark red, but some are 

 Avhitish. Tips of the digits black and spoon-shaped. The left chela 

 is the larger, compressed, and covered with coarse granules. This 

 is from Bermuda, tig. 59. 



This species appears to be rare in Bermuda. We obtained one 

 specimen in 1898; another in the Yale Museum v/as collected by 

 Dr. F. V. Hamlin about 1877. Its range is from Florida to Brazil. 

 Porto Rico (Benedict as insignis); ?Maceio and Rio Goyanna, Brazil, 

 on reefs (Rathbun as insignis). 



About a dozen good specimens of this conspicuously colored spe- 

 cies were obtained at Dominica Island by A. II. Verrill, in 1906 

 (Yale Mus.). The}^ Avere taken in baited fish-traps in 10 to 25 

 fathoms. They occupied shells of Triton iKiriegatus, Mxtrex, and 

 half-grown Strotnhus gigos.

This species is pretty closel}^ allied to D. insignis, but is easily 

 distinguished by the armature of the chelne and second left ambulatory 

 leg. The eye-stalks of the latter are also shorter (see tig. 59), not 

 reaching to the end of the antennal aciculum, and the ocular scales 

 are different in form. In D. iiisignis the second left ambulatory leg 

 has no median carina on the outer surface (see fig. 59, and Plate xxvi, 

 4, 5), the oblique ridges and long rows of small tubercles curve back- 

 ward and meet in "herring-bone" fashion along the convex middle 

 line, on the pi'opodus, but are interrupted by a groove on the dactylus; 

 they are armed with appressed plumose hairs, as in J), venosus.
