the following joints, when they are folded up; in this furrow especially the carpus is con- 

 cealed for more than half of its breadth, when thus bent upwards, the metacarpus 

 standing out rectangularly with the long dactylus pointing downwards. The genu is 

 as long as broad, the under hind corner is fringed with four or five Ions' bristles. The 

 tibia is somewhat longer than the genu; the under margin is rectangularly produced, 

 and is provided with three or four long bristles. The carpus is a little shorter than 

 the metacarpus, and somewhat broader, but does not form with it, neither a subcheli- 

 form, nor a folding, hand, x ) the articulation of the metacarpus not allowing it to be 

 folded up along the hind margin of the carpus. The front margin of the carpus is nearly 

 straight, without bristles; the hind margin is feebly convex, notched, and fringed with 

 a row of five or six long, stout bristles. The metacarpus has the front margin strongly 

 convex, and set with long bristles, the hind margin is straight, serrated, and bordered 

 with some long bristles. The dactylus is very long, curved, and finely serrated at the 

 base of the hind margin; it is about a fifth part shorter than the metacarpus. Glands 

 are developed in the first four joints. 



The second pair (Pi. XII, fig. 13) reach about to the middle of the carpus of the 

 third pair. The femur is linear, smooth, and somewhat shorter than the four following 

 ioints together. The genu is as long as broad, Avith six or seven long bristles along the 

 under margin. The hind portion of the tibia is produced to the middle of the stem of 

 the carpus into a spoon-shaped process, the lower margin of which is fringed with six or 

 eight long bristles. The front and hind margins of the carpus are straight and smooth; 

 the carpal process, which is narrow and gouge-shaped, is a little more than half as long as 

 the stem of the carpus, and two-thirds as long as the hind margin of the metacarpus; 

 the terminal spine is long, more than half as long as the process itself, and reaches fully 

 to the apex of the metacarpus; the margins of the carpal process are fringed with long 

 bristles. The metacarpus is thick, conical, with bulging sides, and quite as long as the 

 stem of the carpus; the front margin is feebly convex and fringed with eight or nine 

 bristles; the hind margin is convex, and serrated. The dactylus is nearly straight, and 

 scarcely more than a fourth part shorter than the metacarpus. 



The third and fourth pairs (PI. XII, fig. 14) are similar in shape, but the fourth 

 are a little longer than the third; their last joints form a perfect folding hand. The 

 femur is somewhat more than twice as long as broad; the front margin is almost straight 

 with a furrow for the reception of the following joints, and with the lower corner obtusely 

 rectangular; the hind margin is convex, with two or three bristles below the middle, 

 and one at the apex. The genu is fully as long as broad, with two bristles on the hind 

 margin. The tibia is more than twice as long as the genu, with three long bristles 

 on the hind margin, and the lower front corner a little produced downwards. The 

 carpus is narrowly ovate, a little broader in the adult individuals than in the younger; 

 the front margin is smooth, the hind margin is notched and provided with four or five 

 very long bristles, the longest fully as long as the breadth of the joint; the carpus is a 

 little longer than the two preceding joints together. The metacarpus is thick and stout,
