 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. 



Restricted to North American waters. 



Analogous species on opposite sides of the continent: byssomia^ 

 (Atlantic); canfieldi (Pacific).
