MUNNA krOyeri. 327 



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 antennse 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 antennae and the proximal half of the third 

 joint. The external antennae 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 the seventh is obsolete.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-
