Diagnosis. — Postocular projection a flat oval lobe; hepatic pro- 

 jection a slender, transverse spine. Merus of chelipeds carinated on 

 three margins; carpus tricarinate above. Ambulatory legs not cari- 

 nate. Ischium of maxillipeds and also exognath grooved. 



Description. — ^A small species. Carapace sub triangular; in its per- 

 fect state it is covered with short cutaneous vesicles which form 

 prominences on the protogastric, mesogastric, cardiac, intestinal, 

 hepatic, and branchial region (3 dorsal). The anterior part of the 

 protogastric region, as well as the rostrum and the antero-lateral 

 margin of the branchial region are covered with curled setae. When 

 these coverings are removed, there is a large tubercle on the cardiac 

 and intestinal regions and on each protogastric lobe; median gastric 

 tubercles obsolescent; branchial regions not areolate. Lateral mar- 

 gin with two spines, the hepatic one slender, transverse or nearly so, 

 and almost horizontal, the branchial spine stouter and upturned. 

 Postocular tooth thin, obtuse, its upper surface flattened in a smooth 

 oval plate inclined downward from the horizontal at an angle of 



'» The jar from which the type specimens were taken contained mixed lots from Catalina Harbor and 

 Monterey, as P. dalli has not yet been found north of the Santa Barbara Islands, it is reasonable to assume 

 that Catalina Harbor is the type-locality.
