Fig. 93. Pagurus californiensis, 3, X 2; a, dorsal view; b, anterior portion 
of carapace, enlarged (after Faxon). 
Characters.—Small hand very feeble, less than one-third the greatest width of 
the palm of larger hand. Large hand more or less suborbicular, feebly granulated 
on palm. Anterior portion of carapace about as broad as long, median projection 
of front triangular, acute. Hye-stalks moderately long and slender, about three- 
fourths as long as anterior portion of carapace. Acicle not exceeding eye-stalks. 
Ambulatory legs glossy, nearly smooth; from upper distal margin of carpus a 
small spine extends forward over propodus; dactyls thin, pubescent, not twisted, 
but little curved, spinulous below, and exceeding length of the propodi. 
Dimensions.—Two male types: length 26 mm. and 20 mm., respectively. 
Color.—Alecoholic specimens nearly orange in color, the ambulatory legs crossed 
by bands of a lighter color. There is a band of lighter color near the middle of the 
ocular peduncles (Holmes). 
Type Locality California. 
Distribution.—From Monterey Bay or Santa Catalina Island, California, to 
Gulf of California, 8 to 58 fathoms. 
Genus Pylopagurus Milne Edwards and Bouvier 
Abdomen with paired appendages, other than the uropods on the first abdom- 
inal segment in the female only. External maxillipeds widely separated at base; 
exopodites of all three pairs of maxillipeds flagellate. Chelipeds dissimilar and 
unequal, the right vastly the larger; large hand more or less operculiform, greater 
part of upper surface transversely concave, trough-shaped, or discoidal with 
raised margins; bent at an angle to the wrist. Fourth pair of legs subchelate.
