THE CRUSTACEA OF NEW JERSEY. 431 



Eyes rounded, smaller than rounded stalks, which nearly 

 completely fill orbit, and outer basal surfaces villose. Anten- 

 nules robust, two joints in peduncle semicylindrical and subequal. 

 Antennules each with two attenuated flagella surmounting ter- 

 minal joint, upper a little longer, ends in filament, with bunch of 

 setae on its lower edge, and in length a little shorter than terminal 

 joint of peduncle. Antennae attenuated, slender, basal joint of 

 peduncle largest, second joint but little less in width though of 

 about equal length, and flagella extends laterally to outer edge 

 of orbit at least. Subbranchial regions more or less villose. 

 Outer maxillipeds with long ischium, merus about broad as long, 

 and other three terminal joints subequally long. Inner and outer 

 edges of maxillipeds hairy, though above and about bases 

 of three terminal joints quite hairy. Chelipeds subequally en- 

 larged, left a little larger, and both more or less finely granular. 

 Dactyl and pollex robust, their cutting-edges mostly in contact, 

 with several enlarged keeled though obsolete denticles. Pro- 

 podus with keel above, though rounded convexly below, and five 

 more or less distinct longitudinal ridges on outer surface. 

 Tubercle on upper posterior marginal region of propodus ex- 

 ternally at its articulation with carpus. Inner surface of pro- 

 podus without keels. Carpus with large inner triangular tubercle 

 or spine above in front. Merus unarmed. First pair of ambula- 

 tory legs longest and fourth shortest, though with all joints but 

 slightly more compressed than others. First and last legs with 

 few close-set setae along lower edges of dactyls and propodi. 

 Postabdomen rather broadly ovate. 



Color reddish-brownish, dotted or specked with darker above, 

 paler below. Length of carapace 37 mm., width 54. 



Remarks. — A widely distributed species ranging along our 

 Atlantic coast from. Labrador to the Gulf of Mexico. It lives in 

 salt pools and inlets along the shore, and often occurs well up 

 to the limit of high tide. The males are sometimes pugnacious, 

 and will battle among themselves. In our region it lives 

 often on the sandy shores, though also frequents rocky or stony 

 bottoms equally well elsewhere. It is devoured by numerous 

 fishes, such as cod and black bass, though many others doubtless
