Characters.—Carapace covered with sharp spines of unequal length. Rostrum 
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 subecarinated 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 Kroyer 
Carapace broad, depressed, more or less tuberculated or spinose. Rostrum 
short, flattened, notched, not depressed. Basal antennal joint very narrow, with 
a terminal spine; flagellum 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.
