short, sharp, and slightly curved. The four anterior coxse 
are large, quite as deep as the segments of the body to 
which they are attached respectively, and each has the 
inferior margin fringed with a row of equidistant, soli- 
tary, short, plumose spines. The first pair of legs are 
slender, tolerably long, having the metacarpus and wrist 
fringed upon the inferior side with a few plumose cilia ; 
hand long, narrow, tapering ; palm two-thirds the length 
of the hand, exceedingly oblique, defined by a small 
obtuse denticle, and fringed with a row of equidistant 
fine cilia : finger long and slender, as long as the palm, 
and nearly straight. The second pair of legs resemble 
the first, but are scarcely as large, and the palm is 
slightly waved, and not so distinctly defined, and the 
finger appears to be scarcely as long as the palm. The 
third and fourth pair of feet are slender, fringed with 
cilia, both plumose and simple, having the hand straight 
and unarmed ; the finger as long as the hand, straight, 
stout, and furnished with a nail at the extremity ; on the 
distal extremity of the hand, on each side of the finger, 
stands a moveable spine, as stout and long as the finger, 
apparently having the power of being compressed to- 
gether, each fitting into a lateral groove in the finger, 
thus forming a feeble and insufficient nipper. The fifth 
pair of legs are long, slender, and plumose, the coxa is 
short, and the thigh tapering, with a posterior concave 
margin to the distal extremity; all the joints after the 
knee are subequal in length ; the finger is quite straight. 
The sixth pair of legs resemble the preceding in form, 
but are nearly half as long again; the joints after the 
knee are subequally long and slightly plumose ; the 
finger is longer than the hand, straight and styliform. 
The seventh pair of legs are very short, reaching only to 
the middle of the metacarpal joint of the sixth pair of
