Carapax ovate, spineless, with all the regions strongly protuberant, and 
separated by deep grooves. Rostrum short and very wide at the base, 
flattened horizontally into a leaf-like form, horns acute. In females the 
regions are less elevated. Prof. Smith (loc. cit.) points out that Dana’s 
figures were drawn from females and young males. In adult males the 
chelipeds are proportionately much larger in every way.

Oregonia hirta Dana, loc cit. PI. III., f. 3. 
Stimpson Bost. Journ. Nat. Hist. Vol. VI., 1857, p. 456. 
Carapax triangular, rounded behind, its surface rough and granular, 
slightly pubescent. A long, slender, nearly transverse spine behind the 
orbit. Rostrum dividing into two long, slender nearly parallel horns which 
are, usually, in life decorated with algae, sertularians, etc. Mr. J. I. Smith 
points out (loc. cit. supra) that the larger males agree with Dana’s descrip- 
tion of O. gracilis and the females with O. hirta. The adult female specimens 
have a very broad nearly orbicular abdomen, while the apparently sterile 
females, though large, show considerable approach to the male in the form 
of the carapax, etc., and their abdomen is much narrower and elliptical.

The post orbital expansions have two acute lobes; carapax more triangular 
than in gracilis, and armed with short spines in the different regions ; 
anterior feet large.
