BATHYPOREIA PILOSA.

lengths. The inferior antennae are more slender than, 
and nearly twice the length of, the superior, the 
peduncle reaching to the extremity of the superior 
antennae ; 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 Lindstrbm 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
