Diagnosis. — Carapace tviberculate. Coxal joints of legs with an 

 entire lobe; merus joints with one spine on anterior margin. 



* Description. — Differs very slightly from the preceding. The lobes 

 on the coxae of the legs are rounded, not dentate (see fig. \tAh). 

 Usually no series of prominent tubercles on the gastric region. The 

 tubercles of the carapace are variable, either prominent, or depressed, 

 or almost obsolete on the convex portions of the carapace. Fringes of 

 bristles also variable in extent, sometimes absent. The epistome has 

 a tendency to be more divided than in P. depressa^ into seven lobes, 

 but this is not a constant character. Outer surface of palms rougher, 

 especially in the male AAhere the tubercles are well develo])ed and 

 arranged partly in longitudinal, and partly in transverse rows. 

 The chelipeds in the adult male are half again as long as the cara- 

 pace, in the female about as long as carapace. 



Measurements. — Male (18826), extreme length of carapace 51.8, 

 width of same 55.2, fronto-orbltal width 32.1 mm. 



Range. — Cape St. Lucas (Stimpson). Also throughout tlie Orien- 

 tal Region, from the Hawaiian Islands westward and southward to 

 Japan and the Arabian Sea. 



Remarks. — This subspecies is not always well separated from 

 typical depressa. See de Man, Notes Leyden Mus., vol. 5, 1883, 

 p. 108.
