Notes on North American Crustacea. 91 



margin with seven or eight short, irregular teeth ; carpus and hand 

 evenly oblong, granulated above and below, granules depressed, largest 

 and most crov?ded on the fingers ; carpus nearly twice as long as broad ; 

 hand a sixth part longer than the carpus ; dactylus four-fifths as long as 

 the palm ; outer edge of immovable finger rather sharp ; tips of fingers 

 calcareous. Left cheliped short, in full-grown specimens not reaching 

 to the posterior margin of the right hand ; surface granulated as in the 

 right cheliped ; meros smooth below ; superior edge of carpus sharp 

 and armed with four or five short spines ; hand convex, prominently 

 granulated, and showing at the middle of the base above, indications of 

 a groove and carina, which are not, however, continued further. Ambu- 

 latory feet short, spinulose along the superior edges; dactyli longer 

 than penult joint, not twisted, their edges not sharp, tips long, corneous. 

 Color reddish ; feet regularly maculated with light-blue or yellowish spots, 

 very small, oblong, sub-equal ; tubercles of under side of meros white. 

 General length, 2*4 ; length of carapax, 0*47 ; width of front, measured 

 between outer bases of antennae, 0*22 inch. 



This species resembles E. middendorffii in its proportions, 

 but is readily distinguished by the more strongly granulated 

 surface of its chelipeds, and the spinules on the superior edges 

 of the other feet. 



Found at Monterey, Cal., by Mr. Taylor, and in Puget Sound 

 by Dr. Kennerly.

Carapax smooth, nearly naked. Rostral point very obtuse. Eyes 

 very long and slender, somewhat tapering, slightly curved, and reaching 

 to the extremity of the peduncle of the outer antennae ; cornea scarcely 

 at all dilated. Ophthalmic scales short and broad. Feet sparsely hairy. 

 Chelipeds spinulose above, beneath smooth and naked. In the right 

 cheliped the palm of the hand is large, longer than the carpus, and one- 

 half longer than the fingers ; — the fingers are each armed with a tooth 

 within at the middle. Left cheliped reaching to the middle of the
