244: Notes on North American Crustacea. 



with long liairs. Feet pilose above, and of a pale orange color, anrni- 

 lated with dark purple; four or five rings on each ambulatory foot. 

 Right cheliped very long, moderately and evenly granulated or scabrous 

 above ; carpus nearly twice as long as broad, and as long as the palm 

 of the hand, spinulose along the inner margin ; hand large, oblong-ovate, 

 with long palm and short slender fingers. Beneath, the carpus and 

 hand are convex, naked, and obsoletely granulated. Left cheliped very 

 small, scarce over-reaching the extremity of the carpus of the right one, 

 slender, rather compressed, spinulose and hairy above; hand rather 

 smaller and shorter than the carpus ; fingers somewhat longer than the 

 palm and slightly gaping. Ambulatory feet slender, compressed; those of 

 the right side as long as the right cheliped ; a small spine at the extre- 

 mity of the carpus joint ; dactylus much curved, a little longer than the 

 penult joint, scarcely twisted, with smooth, unarmed, sparsely pilose mar- 

 gins. Usual length about an inch. Length of carapax, 0.19 ; breadth 

 of front, 0,11 ; length of greater cheliped, 0.52 ; of carpus and hand 

 together, 0.34 inch. 



It is allied to E. hrevidactylus^ but has the right cheliped 

 much more elongated and less prominently granulated above. 

 Also, the dactyli of the ambulatory feet are rather longer. 



It is common in small univalves dredged in Beaufort Harbor, 

 l!T. C, and off the coast adjacent, in from two to eight fathoms 

 on bottoms of shelly sand. 



GALATHEOIDEA. 



Huiiida caribaea, nov. sp. 



The species of Munida have all great resemblance to each other, and 

 the present species forms no exception to this rule. It has the usual 

 characters of front, spinous gastric and hepatic regions, etc. The par- 

 ticulars in which it differs from other species are the following. The 

 rather convex carapax is more narrowed anteriorly. The anterior two- 

 thirds of the lateral margin is armed with six or seven equal and equi- 

 distant spines. Eye-peduncles longer, and cornea less dilated than 

 usual. Chelipeds very long, cylindrical, uniformly scabrous ; and armed
