buccal cavern, and wider above than below. Width of 

 ischium about three-fifths its length, and length of merus about 

 two-thirds its own width, a little larger than propodus and 

 conic dactylus equals or a trifle longer than merus. Chelipeds 

 a little unequal, robust and swollen. Propodus with slight or 

 obsolete outer groove above longitudinally, surfaces otherwise 

 convex. Dactyl and pollex robust, compressed, former a little 

 more curved, edges of lesser cheliped usually approximated, and 

 those of greater nearly so. Cutting-teeth sharp-edged, irregu- 

 lar, larger and better developed in left organ. Propodi usually 

 wnth irregular color-markings, fingers with smooth surfaces 

 contrasting to rest of very minutely granulated surfaces of 

 chelipeds. Dactyl less than half length of propodus, and with- 

 out a large tubercle at base or on front outer edge of hand. 

 Carpus with well-developed spine on upper inner angle, and one 

 also on merus in same location. Carpus and merus of about 

 equal length. Ambulatory feet similar, outer joints more or less 

 hairy on edges, and fourth pair shortest with long slender 

 dactyls but trifle shorter than those of first pair. 



Color mostly pale grayish-brown, and this general tint more or 

 less uniform, with slight lilac tints on lower surface of body. 

 Feet all slightly brownish. Chelipeds largely brownish like rest 

 of body, though fingers lilac to slaty, darker basally and whitish 

 at tip. Dactyl same shade as pollex, only extent of color of latter 

 extends back on propodus, at least along its lower edge, for about 

 three-fifths its entire length. Eyes dark. Length of carapace i6 

 mm., width 20 mm. 



Remarks. — This form, as now understood, ranges from 

 Massachusetts to Virginia, being replaced southward by Neo- 

 panope texana (Stimpson), of South Carolina, Florida and the 

 Gulf of Mexico. This latter is said to differ in having pale- 

 colored fingers in the male, and also in having the anterior lateral 

 teeth blunter and less produced. Though my examples, obtained 

 at Spray Beach on Long Beach Island in Ocean County, during 

 the past June, certainly have pale-colored fingers at present I 

 am unable to say what color they were in life. This species is 

 found in salt water like Bnrypanopeus deprcssus, wath which it
