335. EUPAGURUS MEGALOPS' Slimpson 



Pi^ATU XXIV, Fig. 2 



Eiipagurus megalops Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. 248 

 [86], 1858. 



Carapax naked ; anterior region smooth, g-lossy, and flattened. 

 Median lobe or tooth of front broad, obtuse, and less prominent than 

 the lateral teeth. Eyes rather remote from each other, shorter than 

 the peduncle of the antennae by one-third the length of the latter, 

 and with the cornea greatly swollen, so that its diameter is nearly 

 twice that of the peduncle at its base. The acicle of the antennae is 

 slender from its base, slightly ciliated, and reaches the extremity of 

 the eye ; the flagellum is naked, and reaches beyond the ambulatory 

 feet for a fourth of its length. Chelipeds ciliated on the margins ; 

 the right one a little shorter than (that is, overreached by) the ambu- 

 latory feet; carpus oblong, one-half longer than broad, above sharp- 

 granulous and setose, the setae short and arising from the anterior 

 bases of the granules ; hand broader than carpus, but scarcely more 

 than half as broad as long, tapering and depressed, but convex along 

 the middle ; upper surface of the hand roughened with sharp gran- 

 ules smaller than those of the carpus, and very sparsely scattered, 

 there being very few on the convex middle portion of the hand, but 

 more at the sides ; fingers hairy, much shorter than the palm, and 

 with calcareous, hooked tips. Left cheliped slender ; carpus trig- 

 onal, superior keel spintilous and separated by a longitudinal groove 

 from another keel situated to the right and beneath it ; hand as long 

 as the carpus of the right cheliped ; palm convex and obsoletely
