Fig. 129. Pugettia richti, g, dorsal view of carapace and chelipeds, x 4% 
(after Dana). 
Characters.—Carapace ovate, tuberculated; median region tumid and furnished 
with four tubercies, the three anterior of which are nearly abreast (median one a 
little in advance of the others) ; two double rows of curved setae in front of lateral 
tubercles, and two similar rows on the rostrum; cardiae and intestinal regions 
each with a tubercle; two tubercles on branchial region, one before the other. 
Rostrum prominent, horns divaricate and convex above, triangular notch between 
them hairy. Preocular tooth acute and directed forward, outward and upward; 
postocular acute and triangular. Hepatic expansion of carapace narrow, trans- 
verse, postocular and first anterolateral tooth acute and distinct; at posterolateral 
angle of carapace there is a prominent pointed tubercle. Surface of ischium of 
maxillipeds plane, but sometimes bearing a trace of a longitudinal groove; 
exognath not grooved. Chelipeds large in adult males, much shorter and more 
slender in females; the merus bears a few tubercles on the upper side but no 
carina, but it is generally rounded in young males and females; the carpus has 
two or three carinae which become more or less prominent in old males; hands 
compressed, upper edge acute; fingers shorter than the palm, and gaping at the 
base in old males. 
Dimensions.—Type, male: length of carapace 48.7 mm., width between tips of 
teeth across gastric region 32.6 mm., width between tips of teeth across cardiac 
region 36 mm. Large male: from tip of rostrum to back of carapace 40 mm., width 
between the tips of the posterior teeth 30 mm. (25 mm. between their bases) 
(Weymouth). 
Color.—tIn life red, varying from bright to dark, and often closely matching 
certain of the encrusting corallines (Weymouth). 
Type Locality. California. 
Distribution.—British Columbia to San Diego, California, low tide (Rathbun).
