Chelipeds rather slender; hand long, slender, smooth, incurved; dactyl about one- 

 half total length of palm. 



Dimensions. — Type, male: length of carapace 30.2 mm., width 21.2 mm. The 

 specimen taken outside of Golden Gate measured, carapace and rostrum over all, 

 28 mm. 



Color. — Tan or gray, with dots and small markings of red; color however 

 cannot be seen until decorative material is removed (Way). 



Type Locality. — Puget Sound. 



Distribution.- — From Bering Sea at Nunivak and Bering Island, to Monterey 

 Bay; 5 to 135 fathoms. Japan (Balss). 



Biological Survey of San Francisco Bay. — Oregonia gracilis though 

 not taken in connection with any of the regular bay stations was 

 obtained in July, 1912, by Mr. Johnston while observing the trawling 

 operations of the A. Paladini Company on the fishing grounds outside 

 of Golden Gate (approximately located in the general vicinity of 

 D 5785-5787, 39 to 41 fathoms). The only temperature records avail- 

 able for the fishing grounds were made in October of the same year 

 when the bottom temperature ranged from 9.8° to 11.0° C, and the 

 salinity 33.8 to 34.2. 



Genus Inachoides Milne Edwards and Lucas 



Carapace longer than broad, cardiac, branchial and gastric regions swollen. 

 Rostrum short and simple, with triangular base terminating in a spine; basal 

 article of antennae with an antero-external tooth. No supraocular spine, post- 

 ocular present, usually well developed and directed forward. Merus of outer 

 maxillipeds cut at the antero-internal angle for the insertion of the palp ; antero- 

 external angle rounded. Abdomen of male with last two segments and of female 

 with last three segments coalesced, inclusive of the telson; first segment armed 

 with a spine or spine-like tubercle. Chelipeds enlarged, palms swollen; ambulatory 

 legs slender, moderately long, first pair longest; subprehensile, propodal joints 

 more or less enlarged distally; dactyls curved, folding against the propodi.

 Characters. — Carapace broadly triangular, pyriform, convex; surface granu- 

 late and tuberculate, with fine pubescence; tubercles tend to become spinous on 

 lateral margins and on summit of branchial regions; on median line there is a 

 spiny tubercle on the posterior part of gastric region, and a stout, spine-like 

 tubercle on cardiac and on intestinal region. The median spines present in adult 

 males become tuberculate in females and in smaller specimens, and the gastric 

 tubercle is often absent. There is also a shorter spine-like tubercle on first
