is 21 ] Schmitt: The Marine Decapod Crustacea of California 125 



Distribution. — From San Francisco to San Diego, California, and the Gulf of 

 California, to a depth of 116 fathoms. 



Remarks. — Occasional specimens have the eye-stalks almost as long as the 

 greatest width of the anterior portion of the carapace, but the characteristic 

 broad hands will always serve to distinguish P. bakeri from the other species 

 here listed. 



Biological Survey of San Francisco Bay. — Paguristes bakeri was 

 only taken at three of the seventeen outside dredging- stations, D 5787, 

 5789, 5790, all between 33 and 46 fathoms. One specimen was taken 

 at the first, and the third station, on a "very fine, green sand" bottom, 

 while two specimens were obtained at the second, on "very coarse 

 variegated sand with a small proportion of fine sand." At each of 

 these stations this species was associated with Pagurus ochotensis, in 

 addition at the second with Paguristes turgidiis, and at the last with 

 Pylopagurus minimus. Seven other specimens, also in company with 

 Pagurus ochotensis, were obtained on the fishing grounds by the com- 

 mercial trawlers, July, 1912. The bottom temperature range as 

 observed for this species was 9.4° to 11.0° C ; salinity 33 to 34.3.

Description. — Anterior portion of carapace longer than wide; front tridentate, 

 rostriform tooth triangular, acute, extending forward at least to base of the eye 

 scales, exceeding lateral teeth by one-half their length; lateral teeth blunt and 

 somewhat tubereuliform. Eye-stalks comparatively very long and slender, length 

 measured from orbital margin about as long as greatest width of anterior portion 

 of carapace, or slightly longer; eye scales each with four to five spiniform teeth 

 at tip; third segment of antennular peduncle exceeds cornea by one-fourth its 

 length. Antennae thickly long-haired beneath, few short hairs above. 



Chelipeds equal, hairy; merus spined on upper or anterior edge and on inner 

 border of lower face, outer border of lower face of merus in occasional specimens 

 slightly rugose, and in one specimen from Monterey somewhat spinulose; carpus 

 with five stout spines on upper inner edge; upper surface of hand well spined 

 with dark tipped spines, which are larger on the outer anterior edge of the im- 

 movable finger; inner edge of palm behind the dactyl armed with three prominent 

 spines, with two much smaller ones below on inner face, and intermediate between 

 them. Hands somewhat like those of P. turgidus, one-third to sometimes nearly 

 one-half longer than wide, but with fingers less acuminate. 



Ambulatory legs very hairy on inner or anterior face of dactylus and pro- 

 podus, anterior pair more so than in any of the species listed in this paper, 

 armature of anterior pair much as in P. bakeri. 



Dimensions. — Holotype, male (Cat. No. 50427, IT. S. N. M.) : length 59 mm., 

 length of carapace 22 mm., of anterior portion 12 mm., greatest width of anterior 

 portion of carapace 10 mm., length of right cheliped 33 mm., of hand 13 mm., 

 width of hand 7 mm., length of eye-stalk measured from orbital margin 10 mm. 

 Of paratype, female : length 31 mm., length of anterior portion of carapace 9 mm., 

 width 8 mm., length of eye-stalk measured from orbital margin 8 mm.
