chelipeds of females and young males relatively smaller; fingers contiguous and 
dentate along entire inner margin. Abdomen of female elliptical, seven-jointed, 
counting telson; of male, widest at third segment, narrowing rapidly to fifth 
which is about equal to sixth, telson narrow and longer than preceding joint. 
Dimensions.—Type, male: length of carapace 27.9 mm., width 33.8 mm.; of 
specimen examined by Holmes, length of carapace 30 mm., greater width 32 mm. 
Color.—A dull purplish tone, the legs crossed by light bands (Holmes). The 
young and even mature (egg-bearing) individuals show considerable variation in 
color, being in general tan or light reddish with the lateral expansions and marks 
on the cardiae region hghter in some cases, almost white. One specimen had the 
entire surface of the carapace, except the rostrum, the abdomen and the chelipeds 
clear white, while the remainder of the legs and rostrum were bright red. The 
legs in the majority show more or less distinct banding. The adults are often 
partially covered by a growth of bryozoa or sponges (Weymouth). 
Type Locality.—Monterey, California, taken from the stomach of percoid fishes, 
‘*Cabesones.’’ 
Distribution—From Unalaska, Alaska, to Mazatlan, Mexico (Rathbun). 
Genus Pugettia Dana 
Carapace with upper surface furnished with spines or tubercles; margins 
behind eyes produced into an alate expansion, behind which it is somewhat con- 
stricted. Rostrum two-spined. Basal antennal joint enlarged at base and nar- 
rowing distally; flagellum of antennae not entirely covered by the rostrum. Pre- 
ocular spine present, large. 
KEY TO THE CALIFORNIA SPECIES OF PUGETTIA 
I. Postorbital projection a triangular tooth. 
A. Hepatic expansion very wide (postocular spine and first anterolateral 
tooth united by a leaf-like expansion of the carapace). Merus of 
chelipeds with a prominent, irregularly dentate carina on the upper 
side, carpus cristate. Ambulatory legs with merus and propodus 
more or less carinated above. Ischium of maxillipeds with a longi- 
tudinal groove, exognath also grooved. ae 
gracilis, p. 206. 
B. Hepatic expansion narrow, transverse (postocular spine and first antero- 
lateral tooth acute and distinct). Merus of chelipeds bears a few 
tubercles on the upper side but no carina; the inner side may become 
strongly ridged in adult males, 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. Ambulatory legs with merus 
and propodus not crested. Surface of ischium of maxillipeds plane, 
but sometimes: bearing a trace of a longitudinal groove, exognath 
not grooved. ihe 
richtt, p. 207. 
II. Postorbital projection an obtuse lobe. Merus of chelipeds with an irregular 
carina on the upper and inner margins, carpus strongly carinated on the 
inner and upper margins, and irregularly ridged on outer side. Ambulatory 
legs with joints not carinated. Ischium of maxillipeds grooved. (Not 
known north of San Pedro.) ‘alli 208
