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 tubereulate, 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
