type, R. subquadratus Dana. 



Female near Pinnotheres. Carapace marked by two longitudinal 

 sulci which extend backward from the upper margin of the orbits, 

 inclosing between them the median area. The anterior portion of 

 the carapace is so deflexed that the orbital and antennal area is 

 ventrally situated; fronto-orbital distance narrow; frontal margin 

 flush with antennular surface, and not forming a projecting hood; 

 orbits round, eyestalks spherical, corneas small. Terminal segment 

 of palp of outer maxilliped articulating on inner margin of penult 

 segment. Second ambulatory leg longest ; dactyli short. 



Male not known. 



Eestricted to North American waters. 



Analogous species on opposite sides of the continent: byss&miae 

 (Atlantic); canfeldi (Pacific).
