lengths. The inferior antennas are more slender than, 

 and nearly twice the length of, the superior, the 

 peduncle reaching to the extremity of the superior 

 antennas ; the flagellum, which consists of one long 

 and four or five articuli of irregular lengths, is scarcely 

 as long as the peduncle. The first pair of legs are 

 wanting in the only specimens that we have been 

 enabled to procure : but Lindstrom describes them as 

 " having the wrist longer than the hand ; the hand 

 ovate, palm imperfectly defined." The second pair have 

 the wrist very long, and ciliated upon the inferior 

 margin ; the hand is straight upon the upper margin, 

 the palm, receding from the distal-pointed extremity, 

 forms with the inferior margin a convex line, the an- 

 terior limit of which is fringed with extremely long 

 cilia ; the posterior is slightly excavated, suggesting that 

 the hand is capable of being impinged against the 

 preceding joint, and thus obtaining a feeble prehensile 

 grasp, which it has otherwise lost by the absence of the 

 moveable finger. The next two pairs of legs have the 

 metacarpal joints and wrists much dilated ; the hands 

 are long and slender, and appear to have the capability 

 of being bent back against the wrist ; the fingers in 

 these are short and strongly developed ; -a few hairs 

 fringe the inferior margin of the hands and wrists. 

 The next pair of legs have the thighs dilated towards 

 the distal extremity ; the metacarpal joint is broad, but 

 the wrist is narrow, with its extremity produced ex- 

 ternally to a point ; the hand is long and narrow, having 

 the margins parallel ; and the finger is nearly as long as 

 the hand. The thighs of the two succeeding pairs of 

 legs are more broadly dilated than that of the preced- 

 ing. The last pair of caudal appendages have one very 

 long and one very short branch, the longer branch being
