having the posterior margin fringed with long plumose 
hairs ; the wrist is short, scarcely longer than broad, and 
having the posterior margin fringed with long plumose 
hairs ; the foot is three times as long as the wrist, — it 
has the margins almost parallel, tapering towards the 
distal extremity; the outer margin, towards the distal ex- 
tremity, has long plumose and a few short simple hairs ; 
the inner has, at the same extremity, four or five short 
stout spines : the finger is longer than the hand, very 
slender, and almost straight ; it is capable of impinging 
laterally against the inner margin of the hand, the apex 
reaching beyond the wrist. The fifth pair of legs have 
the second joint dilated, oval, being enlarged as much 
anteriorly as posteriorly ; the fourth and fifth joints are 
subequal in length and size ; the latter terminates ab- 
ruptly, and has the extremity furnished with five or six 
short blunt spinules, subapically tipped with a single 
cilium, and a few long hairs, which have their margins, 
for nearly the distal half, serrated deeply ; the foot is 
much narrower than the wrist, but is quite as long, — it 
has the margins almost parallel, the extremities being a 
little narrower than the diameter of the middle of the 
joint; the anterior margin is furnished with a row of 
equidistant, short, obtuse-pointed spines, subapically 
tipped with a single cilium ; towards the extremity of 
the foot the spines gradually increase in length and in 
sharpness, until on the apex they pass into the character 
of hairs ; the posterior margin has the distal half mi- 
nutely crenulate, and armed with three spines, which 
gradually increase in length and strength the nearer 
they approach the finger, in the last of which the sub- 
apical cilium has increased in strength until it has be- 
come as important as the primary division ; the finger
