Characters.—Carapace flat behind, in front quite strongly convex longitudin- 
ally but nearly plane transversely; lobes of front separated by a wide, rounded 
notch and furnished with a rounded tooth at the inner and outer angles, between 
which are several small baccate protuberances; inner orbital angle prominent, 
separated by a deep notch from outer angle of front; upper orbital margin with 
a rounded tooth which is bounded by a pair of sulci; postorbital tooth small and 
continuous externally, with a rounded protuberance; the latter separated by a 
smooth sulcus from a pair of smooth, rounded prominences, one of which is sit- 
uated directly above the other; the three posterior teeth on the anterolateral 
margin prominent, the last two curved forward, the first obtuse and generally 
more or less bifid; usually there is a small tooth behind the one at the anterolateral 
angle. Chelipeds stout, more or less unequal; carpus thickly covered with promi- 
nent, rounded, smooth, glossy, rose colored tubercles; hand oblong, with palm 
longer than wide, upper and outer surface covered with tubercles like those on the 
carpus, arranged in seven or eight longitudinal rows; fingers stout and black 
colored, color not extending back upon hand. 
Dimensions.—Type, female: length of carapace 17.3 mm., width 27.7 mm. An 
egg-laden female measures 24.6 mm. long on the median line of the carapace and 
42 mm. wide (Rathbun). 
Color.—In life a uniform dark red, lighter below, fingers black (Weymouth). 
In the alcoholic specimen the carapace is rose color, like the tubercles of the 
chelipeds, which are set on a bluish ground; fingers black, the black not spreading 
on the hand (Stimpson). 
Type Locality.—Monterey, California. 
Distribution —Monterey, California, to Magdalena Bay, Lower California. 
Beach to 55 fathoms (Rathbun). 
Remarks—Abundant under stones between tides and also in kelp holdfasts 
from deeper water (Baker).
