MUNNA KROYERI, O28 
minal joints of the foot-jaws are seen projecting in front 
of the anterior edge, and they are always in motion. The 
dorsal surface of the head is quite smooth, and the internal 
or superior antenne arise from it within the margin, and 
a little anterior to the eyes; they are composed of a 
peduncle of three articulations, and of a double multi- 
articulate setaceous portion, which arises from the last 
joint of the peduncle: these are very slender, and 
incline towards one another at their extremities; the 
whole organ is equal in length to the two first joints of 
the inferior antenne and the proximal half of the third 
joint. The external antenne are much produced, being 
considerably longer than the body; the peduncular 
portion is composed of four joints; the setaceous flagel- 
lum is multiarticulate; two large blood-vessels are seen 
running through these organs. The eyes are large and 
pedunculated, but quite immovable; the reticulated 
portion is small, and is almost altogether confined to the 
lower surface. 
‘* The first six segments of the body are almost equal, 
the seventh is obsolete. The first pair of legs are pre- 
hensile, and the mechanism is rather curious; the fifth 
joint is very large and rounded, the inferior angle of its 
distal extremity is armed with four large and strong 
teeth, two of which are large, the other two being 
smaller ; the sixth joint is not so large, and is reniform ; 
the seventh joint is long and pointed, bearing at its ex- 
tremity a strong claw. The following six pairs of feet 
are ambulatory. ‘They are very spiny, and the last joint 
is armed with two strong claws, which are not placed in 
the usual way, but with the one above the other; the 
superior is largest and strongest. The tail is composed 
of two segments: the first, which is largest, is of a square 
shape, and is armed with two strong spines at its pos-
