l3icarinated, carinse granulated : fingers elongated, depressed, and 

 somewhat curving downward. The whole upper surface of the 

 hands, excepting the fingers, is sometimes pubescent. Heneath the 

 chelipeds are uniformly and crowdedly granulated, and often pubes- 

 cent. Ambulatory feet nearly naked ; upper surfaces smooth, glossy, 

 and inmctatc; u])per margins spinulose ; dactyli contorted, longer 

 than the greater hand, extremel}- slender, sulcated longitudinally on 

 the inner surface, and ciliated above near their extremities. In the 

 third foot of the right side the penult joint is twice as long as the 

 one preceding it. Length of a male specimen, 1.7; length of cara- 

 pax. 0.36; breadth of front, 0.2 inch. 



This can scarcely be the Pagnnis coufoniiis of De Haan, who, in 

 his description of the chelipeds of that species, says, "Pedis minoris 

 carpo non spinoso." It is closely allied to E. gracilipcs, but the eyes 

 are larger and the hands ciliated. 



It was dredged from a sandy and shelly bottom at twenty-six 

 fathoms, in the Xorth China Sea. under the twenty-third parallel of 

 latitude.

Rostriform point large, strongly prominent, and acute. Eyes 

 very short and thick, shorter than the acicle, and but little over half 

 as long as the peduncle of the antennae ; cornea much inflated ; base 

 of the peduncle contracted. Flagellum of the antennae naked ; acicle 

 rather small, with flat upper surface, and both edges somewdiat 

 hairy. Right cheliped long and slender, but considerably shorter 

 than the ambulatory feet ; carpus oblong, proportion of breadth to 

 length. I r 1.5, with the surface subspinulose, as in B. bcnihardus : 

 hand much depressed, thin, elongated-ovate, half as broad as long, 

 convex in the middle, but concave near the thin margins ; nearly 

 smooth above, but sparsely ornamented with minute depressed gran- 

 ules ; outer margin of the hand somewhat expanded and crcnulated : 

 fingers smooth, depressed, with hooked calcareous tips crossing each 

 other : dactylus carinatcd at the superior margin, .\mbulatory feet 

 as in E. bcrnhardns, but with more slender dactyli. General length. 

 i.(S: kngth of carapax. 0.35 ; breadth of froiU, o.n; inch. 



It differs from E. splcmicsccus and E. nwrtoisii in the longer am- 

 bulatorv feet, the terminal ioints of which reach nuich bcvond the
