" Carapace longer than broad, smooth above except where some minute 

 transverse, setose scabrosities or minute squamae are sparsely distributed, 

 occurring most abundantly toward the sides. Margins unarmed, smooth. 

 No sinus at the juncture of the cervical suture with the lateral margin. 

 Kostrum convex above, almost carinated; apex scarcely acute. Inner 

 orbital tooth minute, inconspicuous. Outer orbital tooth (antero-exterior 

 angle of the carapax) far less prominent than the rostrum. Acicle rather 

 short and broad, irregularly somewhat dentated along the exterior margin. 

 Feet subcylindrical, almost naked, rugose above with minute and some- 

 what rounded setose tubercles; dactylus three-fourths as long as the penult 

 joint and armed with a long unguiculus. Plates of the first joint of the 

 abdomen narrow. 



"Length of carapax, 0.4; breadth posteriorly, 0.38 inch." 



Puget Sound (Stimpson); Queen Charlotte Is. (New- 

 combe); Sitka (Schalfeew). 



Judging from Stimpson's description, 0. Brandti is 

 very closely related to this species and not improbably 

 will prove identical with it. The setose squamse in the 

 specimens of Brandti I have seen were thickly set in- 

 stead of ''sparsely distributed," the upper surface of the 

 carapace being almost entirely covered by them, except 

 a small, narrow area along the median line, where they 

 were small and scattered. Stimpson's specimen was 

 probably immature and the character that separates 

 Brandti xndiYhQ due to age. In all the characters except 

 the abundance and distribution of the squamse Brandti 

 agrees with Stimpson's description. Schalfeew consid- 

 ered his Brandti closely allied to, if not identical w^ith 

 inermis, and Bouvier, who had a specimen of the latter
