into one ; the terminal article is a small triangle. The female belt is 

 also sharply earinated on the third article. 



The external maxillipeds have the outer surface tomentose, with a 

 thicker brush of setae along the inner margins of the ischium and 

 merus. The outer external angle of the merus is produced outwardly 

 or laterally in a curious lobe that lies above the exposed end of the 

 exognath. 



The orbits are not fully dorsal ; the eyes are of moderate size and 

 have a "perked up" expression by virtue of the cornea being ter- 

 minally placed and dorsally directed. 



The antennules fold transversely within the f ossett. 



The basal antennal article is characteristically short with its 

 antero-external angle produced into a rounded lobe that lies within 

 the orbital hiatus and is nearly half as long as the second antennal 

 joint ; the flagellum is slender, about one and one-half times as long as 

 the long diameter of the orbit. 



The chelipeds are equal, about two and one-half times as long as 

 the carapace ; the merus projecting slightly more than half its length 

 beyond the carapace, armed with three to five well spaced, acute spines 

 on the anterior margin and with a submedian and a subdistal spine 

 on the posterior border; the carpus has its outer border semicarinate 

 and a distal spine at its outer border; the inner angle is armed with 

 a very sharp spine ; the palm is moderately developed, with four com- 

 plete and one broken longitudinal carinae, the uppermost one forming 

 the upper margin and terminating on a sharp subdistal spine. There 

 is another spine on the palm, at its proximal margin just below the 

 beginning of the second carina. The fingers are nearly as long as the 

 palm, very slender, fluted, the cutting edges toothed throughout their 

 length, the tips decidedly curved. 



The second, third and fourth pairs of legs are very slender, with 

 long, tapered, fluted dactyli. The fifth pair of legs are shorter with 

 the three proximal articles stout, the propodus and dactyl widely 

 expanded, suboval.
