terior portion, X 34% (after Dana). 
Characters.—Carapace lyrate to broadly ovate, tuberculated; number and posi- 
tion of tubercles similar to P. richii, except middle anterior tubercle is small and 
sometimes obsolete, and cardiac tubercle may become scarcely visible in old 
specimens. Rostrum less prominent than in P. richii. Preocular tooth quite 
broad, postocular tooth triangular, acute, and pointing more nearly forward than 
in P. richii. Hepatic expansion very wide, postocular spine and first anterolateral 
tooth united by a leaf-like expansion of the carapace; posterior margin of first 
anterolateral tooth nearly longitudinal. Posterolateral tubercle smaller than in 
P. richii. Ischium of maxillipeds with a longitudinal groove; exognath also 
grooved. Merus of chelipeds with a prominent, irregularly dentate carina on 
upper side; carpus cristate. 
Dimensions.—Type, female: 33.9 mm., width across from tip to tip of lateral 
spines 23.9 mm. 
Color.—Of dorsal surface usually greenish brown, and of ventral side much 
lighter; but specimens found among red algae are a brilliant red (Way). 
Type Locality—Puget Sound. 
Distribution—From Aleutian Islands to southern California, low tide to 40 
fathoms (Rathbun). 
Remarks.—In the figure given above, the left side of the carapace shows 
posteriorly an abnormal occurrence of a second spine.
