cutting edge near the extremity. Feet of the second and 

 third pairs nearly equal ; those on the right side sometimes 

 slightly the longer ; all spinulose and very hairy throughout 

 their length. Tarsi much longer than the penult joint. 

 Color yellowish, obscured by the hirsute covering ; eye 

 peduncles and internal antennae with a longitudinal streak 

 of crimson. Length about three inches. 



It differs from C. cequabilis in its longer tarsi, greater size, 

 and less variegated coloration. It may be distinguished 

 from the other Oregon Paguri by its equal hands and hairy 

 tarsi. 



Found in large shells of the genera Buccinum, Tritonium, 

 etc., in Puget Sound. The specimens described were col- 

 lected by Dr. Suckley.

This species, according to M. De Saussure, differs from 

 A. symnista in having the anterior margin of the carapax 

 less sinuous, and in its long, styliform ocular peduncles, 

 which are closely approximated at the base, leaving the 

 angle between them very acute and narrow.
