428 REPORT OF NEW JERSEY STATE MUSEUM. 



outer half. Front lateral edges of carapace each with ten obtuse 

 flattened serrae, each more or less sharply pointed, outermost or 

 ninth directed outward nearly at right angles. Fine uniform 

 granulations along posterior edges of carapace very evident. 

 Along anterior edges of serrse of anterior lateral region each 

 serrature with two or three at least smaller accessory cusps, 

 giving serras appearance of cut into smaller teeth. Upper sur- 

 face of carapace rather coarsely granular, granules often of quite 

 unequal and irregular size, also quite hairy, especially along 

 lateral edges. Orbit small, rounded, and lower or infraorbital 

 edge projects more anteriorly with innermost of three graduated 

 serrae, which largest, and each of serrae finely beaded with 

 granules. All three infraorbital serrae visible as carapace viewed 

 from above. 



Eyes rounded, smaller than short rounded stalks. Anten- 

 nules robust, of two elongated subequal joints. Antennae 

 slender, basal joint moderate. Subbranchial regions granular 

 and villose. Outer maxillipeds with long ischium, merus trifle 

 broader than long, and other three terminal joints subequally 

 long. Maxillipeds all more or less hairy, especially along inner 

 edges. Chelipeds subequally enlarged, moderately compressed. 

 Dactyl and pollex robust, cutting-edges mostly approximated, 

 each with about five teeth, with median enlarged. Propodus with 

 seven longitudinal series of granules on outer face, three upper- 

 most rows with wide-set small spinous tubercles. Three upper- 

 most of series reflected out on dactylus at least basally, and two 

 lowermost on outer side of pollex. Inner surfaces of hands 

 and fingers mostly entire. Carpus and merus subequal, with 

 several series of spinous tubercles above and on outer surfaces 

 of former, which also more or less hairy. Tubercle on upper 

 posterior marginal region of propodus externally at beginning of 

 third outer series of spinescent granules, or articulation with 

 carpus. Carpus with large inner triangular tubercle or spine 

 above in front, and one well external also on front edge. Ambu- 

 latory legs similar, last pair shortest and more compressed than 

 others. Legs all more or less hairy, especially distal joints. 

 Post-abdomen narrow, triangular, and terminal segment nar- 

 rowly triangular in male.
