dredged from moderate depths— 5 to 12 fathoms. It is found along- 

 shore with P. richii, but is less numerous. 



There seems to be considerable variation in the shape of the two 

 lateral teeth and in the relative widths at these two points. 



"Color a dull purplish, the legs crossed by light bands," Holmes. 

 The young and even mature (egg-bearing) individuals show consider- 

 able variation in color, being in general tan or light reddish with the 

 lateral expansions and marks on the cardiac region lighter, in some cases 

 almost white. One specimen had the entire surface of the carapace — ex- 

 cept the rostrum — the abdomen and the chelipeds clear white, while the 

 remainder of the legs and the rostrum were bright red. The legs in the 

 majority show a more or less distinct banding. The adults are often 

 partially covered by a growth of bryozoa or sponge.

Represented in the collection by two large males brought in by 

 Monterey fishermen from "deep water." The fingers of the cheliped 

 gape at the base, and there is a large blunt tooth on the dactyl which pro- 

 jects into this space. The measurements of the specimen figured are as 

 follows : 



Total length of carapace 165 mm. 



Total width of carapace 123 



Length of cheliped (approximately) 232 



Length of first ambulatory leg (approximately) 268
