as the extremity of the peduncle of the superior ; the fifth 
is hut little longer than the fourth, and reaches nearly 
to the extremity of the flagellum of the superior pair ; 
the flagellum is about the length of the last joint of the 
peduncle, having the first articulus equal to five of the 
succeeding, which are subequally short, and scarcely 
longer than broad. The first pair of legs are moderately 
large, larger in proportion to the second pair than in 
M. carinatus ; the wrist is inferiorly produced to a broad 
plate, reaching nearly to the extremity of the inferior 
margin, and having its edge fringed with fine hairs ; the 
hand is longer than the wrist ; the superior margin forms, 
with that of the wrist, one continuous arcuate line ; the 
inferior margin lies subparallel with the upper, but the 
hand is narrower near the wrist than towards the palm ; 
the palm is convex, armed with two or three rows of short 
posteriorly- curved hooks, and is defined by a strong spine ; 
the finger is about the length of the palm, arcuate, and 
sharply pointed. The second pair of legs have the wrist 
produced along the inferior margin of the hand to the 
extremity, w'here it meets and antagonizes with the 
apex of the finger ; the hand is longer than that of 
the first pair of legs, — it is narrow near the wrist, and 
becomes still narrower at the distal extremity, where 
there is a scarcely -perceptible oblique palm ; the finger 
is short, and only very slightly curved. The third and 
fourth pairs of legs have the hand widening towards the 
distal extremity, the dilated portion taking place anterior 
to the point where the finger articulates with the hand, 
and furnished with a copious brush of hair at the extre- 
mity : the fingers are quite rudimentary. The fourth 
and fifth pairs of legs resemble each other very closely ; 
their coxae are shorter than those of the anterior pairs 
of legs ; their second joints are less enlarged than is
