ORCHESTIIDJJ. 
The eyes in the male are black, irregularly round, 
and situated near the top of the head. The superior 
antennae reach to the extremity of the penultimate joint 
of the peduncle of the inferior. The inferior antennae 
are about one-third the length of the entire animal ; the 
last joint of the peduncle is not longer than the pre- 
ceding ; the terminal articulated portion is about the 
same length as the peduncle. The first pair of legs have 
the hand not longer than the wrist, and the palm about 
half as broad again as the diameter of the hand near 
the centre. 
The second pair of legs have the hands very large, 
long, and tapering anteriorly. The inferior margin is 
slightly concave anteriorly, and no spine, tooth, or angle 
marks the termination of the palm, which appears to 
occupy the whole length of the inferior margin. The 
finger, when closed, reaches to the posterior extremity 
of the hand, but only impinges against it for about one- 
third of its length, the rest standing off so as to leave a 
hollow between the hand and compressed finger. The 
fifth pair of legs are shorter than the two posterior pairs, 
the last being somewhat the longest. They are all stout 
and strong limbs fringed with bunches of stout, blunt, 
spine-like hairs. The posterior pair have, in mature 
males, the wrist and the joint preceding it, developed 
very broadly. The appendages of the tail are short, 
stout, and spinous. 
The female is not quite so large as the male, and 
differs from it but slightly. The first pair of legs are 
longer, and have the palm shorter, so that the inferior 
margin of the hand runs parallel with the superior mar- 
gin. The second pair of legs are small, membranous, 
and feeble. The finger is reduced to a rudimentary
