Characters. — Carapace covered with sharp spines of unequal length. Eostrum 

 long, spines nearly straight, pubescent, and divergent. Basal antennal joint 

 armed at its external angle with a slender spine, with two smaller spines on margin 

 behind it. Postocular spine points obliquely downward. Hands of chelipeds 

 long, slender, compressed; palm subcarinated above, nearly smooth, and generally 

 having a small tubercle on the outer side near the articulation; fingers long and 

 slender. Legs and many parts of the body are covered with a short pubescence. 



Dimensions. — Type, female: length of carapace 40.2 mm., greatest width 

 21.2 mm. 



Type Locality. — Oregon. 



Distribution. — From lat. 57° N, off Kadiak, Alaska, to lat. 32° N, off San 

 Diego, California; 27 to 603 fathoms. 



Genus Chionoecetes Kr0yer 



Carapace broad, depressed, more or less tuberculated or spinose. Rostrum 

 short, flattened, notched, not depressed. Basal antennal joint very narrow, with 

 a terminal spine; fiagellum short. No preocular spine; postocular present; orbits 

 shallow, open above so that the short, thick eye-peduncles are visible from above 

 when retracted. Ambulatory legs more or less compressed.
