Boone, Crustacea, Cruises of "Eagle" and "Ara," 1921-28 41 



palm is two-thirds as wide as long, thick, the upper surface slightly 

 convex and very granulose, these granules coarser and forming a bead 

 along the outer lateral margin ; the fingers are short, triangular, sub- 

 equal, with curved tips and granulose outer surface. 



The first and second ambulatories are subequal, and those of the 

 right side are subequal to those of the left ; the merus, carpus and 

 propodus are short; the dactyl is greatly elongated, subequal to the 

 propodus and carpus taken together, curved, tapering, acuminate with 

 a longitudinal groove on the outer face and with numerous bristly 

 setae. 



The fourth legs are small, with the propodus short and broad, with 

 its posterior margin rounded distally and furnished with a band of 

 movable scales and bristles; the acuminate tip of the propodus is 

 closely appressed to the proximal part of the small dactyl, which has 

 the anterior lateral margin convex, its posterior lateral margin nearly 

 straight and set with spinules, a cluster of setae at the tip. 



The fifth legs are characteristically weakly chelate, with a bunch 

 of stiff hairs distally ; the distal half of the outer face of the propodus 

 and dactyl are set with squamose, flexible scales.
