peds with long ischium, length of merus about-thirds its width, 

 and other three terminal joints subequally small. Inner and 

 upper edges of outer maxillipeds hair)^ Chelipeds about equally 

 enlarged, both more or less smooth. Dactyl and pollex attenu- 

 ated, slender, former with tip fitting inside latter, approximated 

 distally, with a single series of large compressed teeth along each 

 cutting-edge, and three or four enlarged alternately so that series 

 continuous when fingers close. Usually one or two rather con- 

 spicuous tubercles close to base of dactylus on outer edge of 

 palm, and another on inner edge of palm. Upper surface of 

 hand with three longitudinal ridges, inner two of which a little 

 closer. Ridge on outer surface of palm, though not extending 

 forward quite to gape of fingers. Inner surface of palm with 

 an inner ridge similar, though rather obscure. Tubercle at upper 

 front end of carpus. Upper anterior meral edge with three large 

 spines, outer largest. First three pairs of legs similar with edges 

 of dactyls, lower edge of carpi, and both edges of propodi 

 except upper edges of third pair with dense setae. Fourth pair 

 of feet with fine setae along edges of dactyls, carpi, and upper 

 edges of meri and ischia. Post-abdomen quite narrow, with 

 penultimate segment width about two-fifths its length, in male. 

 Female with much broader post-abdomen. 



Color of carapace deep olive, above chelipeds brownish to 

 olivaceous, with bluish at bases of joints and about edges of 

 fingers. Feet brownish, paler below. Entire lower surface of 

 body more or less whitish. Spines along front edge of carapace 

 and on chelipeds reddish. Eyes blackish. Length of carapace 

 115 mm., width 210 mm. 



Remarks. — The most familiar and valued of all our local 

 Crustacea. This is chiefly on account of its abundance, for its 

 flesh is but little inferior to that of any other member of the 

 class. I have examined hosts of specimens in the field, in most 

 everv place where collecting, as at Manasquan, Point Pleasant, 

 Sea Side Park, Barnegat Pier, Great Bay, Bass River at New 

 Gretna, Atlantic City, Ocean City, Corson's Inlet. Sea Isle 

 City, Townsend's Inlet, Avalon, Peermont, Stone Harbor, 

 Anglesea, Grassy Sound, Beesley's Point, Somer's Point,
