A. E. Verrill — Decapod Crustacea of Bermuda. 



387 



In Ko. 829 the larger chela is Si""" long ; IS"""" high ; breadth of 

 carapace, less spines, 66""™. This appears to be the adult of A. 

 Smithii. 



This species appears to be very rare in Bermuda. It has been 

 reported only by Dr. Rankin. Its recorded range is from off Cape 

 Hatteras, 13 fathoms (Smith),* to Rio Janeiro, Brazil, 



Florida (Stimpson). Bahia, Brazil, and Egmont Key, W. Florida 

 (Smith). Bahamas in Sargassum (Rathbuii). 



Achelous spinimanus, var. or subspecies Smithii, nov.

Carapace strongly areolated, and with unusually prominent, 

 arched, transverse ridges, which are coarsely granulated on the 

 front edge ; elsewhere the surface is closely covered with minute 

 hairs and granules; a fringe of long marginal hairs between and on 

 the lateral teeth.

 size. Phot. A. H. V. 



The inner orbital tooth is bilobed, so that there are six frontal 

 teeth, not counting the inner lobe of the orbital, which is ratber 

 shorter than the outer lobe. The four true frontal or rostral teeth 

 are a little prominent, subacute, the two middle ones a little smaller 

 and scarcely more prominent than the others. 



* The smaller specimens from this locality, which I have examined, proved to 

 be a distinct form (A. Smithii nov.), but there were larger ones that I have 

 not seen, now in the U. S. Nat. Museum, which may be the sjnnimanus of 

 Edw., 1879.
