118 Bulletin Vanderbilt Marine Miiseum, Vol. VI 



The first pair of legs are monodactyl, very slender, extending 

 almost as far forward as do the third maxillipeds, and having 

 the dactyl very long, stylet-like, acuminate, and armed on both 

 lateral margins with a series of minute spines, the tip with a tuft 

 of spines. 



The second pair of legs are chelate, with multiarticulate car- 

 pus, which consists of seventeen articles, of which the first and 

 seventeenth are longer, the first being equal to the next four ar- 

 ticles considered together; the second to sixteenth articles, in- 

 clusive, being quite small subequal; the seventeenth article is 

 about two-thirds as long as the first article, or three-fifths of the 

 length of the palm ; the carpus is armed along the upper and lower 

 lateral margins with a series of small, acute, obliquely-set spinules, 

 one on each side of an articulation ; the propodus has a total length 

 of 2 mm.; of this the palm is 1.4 mm., the finger 0.6 m.m, ; the 

 fingers are subequal, slender, meeting throughout their length, 

 their tips are curved and beset on the outer surface with a series 

 of small bristles. 



The third, fourth and fifth pairs of legs are similar, exceedingly 

 slender, the third pair extending beyond the second pair by about 

 half the length of the related longer propodus and dactyl. The third 

 leg has the ichium 1.6 mm. long ; the merus 5 mm. long ; the carpus 

 2.5 mm. long, 0.4 mm. wide; the propodus 4 mm. long, 0.4 mm. 

 wide ; the dactyl 1 mm. long, curved, with an acuminate tip. The 

 meral, carpal, propodal and dactylar joints, inclusive, have the in- 

 ferior lateral margin armed wit ha series of small spinules. There 

 are no epipodites visible on any articles.
