at the lower hind corner. The tibia is more than twice as long as the genu; the hind 

 portion is strongly produced to more than three-fourths of the length of the stem of the 

 carpus, and is fringed with long bristles. The carpus is long, and comparatively broad 

 at the lower end; the front margin is set with four or six bristles, the hind margin is 

 entirely smooth; the carpal process is long and narrow, about a third part shorter than 

 the stem of the joint, and three-fourths as long as the hind margin of the metacarpus; 

 it is provided with a stout apical spine, which is not fully a third part as long as the 

 carpal process; the front side of the process is narrowly gouge-shaped, the front margins 

 are notched and serrated between the notches (PI. XII, fig. 34); each notch carries a stout 

 bristle. The metacarpus is a trifle shorter than the stem of the carpus; the front margin 

 is convex, and set with six or seven long bristles; the hind margin is serrated as in the 

 first pair. The dactylus is feebly curved, and not half as long as the metacarpus; the 

 hind margin is smooth. 



The third and fourth pairs (PI. XII, fig. 35 and 36) are nearly similar in form; 

 the fourth pair are longer than the third. The femur is scarcely longer than that of 

 the second pair; the front side is almost straight, with the lower corner somewhat pro- 

 jecting and squared; the hind margin is convex, and set with short bristles. The genu 

 is as long as broad; the hind margin is armed with two bristles. The tibia is longer 

 and broader than the genu; the front margin is smooth, with the lower corner strongly 

 produced and tipped with a bristle; the hind margin is convex, set with four or five 

 equidistant bristles, and finely pectinated between the bristles. The carpus is elongate- 

 ovate, considerably longer in the fourth pair than in the third; the front margin is smooth; 

 the hind margin is notched and finely pectinated; each notch carries a stout bristle, and 

 between these there are other more slender bristles, which are more numerous in the 

 fourth pair than in the third; the carpus forms together with the metacarpus a perfect 

 folding hand. The metacarpus is only a little shorter than the carpus in the third pair 

 but much shorter in the fourth; the front margin is strongly convex, and smooth; the 

 hind margin is feebly concave, finely pectinated, and bordered with equidistant, short 

 bristles. The dactylus is curved, smooth on the hind margin, and is not half as long 

 as the metacarpus. 



The fifth, sixth, and seventh pairs (PI. XII, fig. 37, 38, 41 and 42) are similar in 

 shape, but unequal in length, the sixth being the longest, owing principally to the much 

 elongated metacarpus, which is about a fourth part longer than in the fifth or seventh 

 pair. The fifth pair (PI. XII, fig. 37 and 38) are only a little longer than the fourth. 

 The femur is considerably shorter than that in the fourth pair; the front margin is con- 

 vex, and set with short bristles; the hind margin is straight, with the usual narrow 

 groove for the reception of the next joints. The genu is somewhat longer than broad, 

 and has the margins smooth. The tibia is much longer and broader than the genu, 

 with the lower hind corner produced downwards and tipped with a bristle; the front 

 margin is provided with four or five bristles, and is finely pectinated. The carpus is elon- 

 gated, more than three times as long as broad, and more than twice as long as the tibia; 

 that in the sixth pair is somewhat more elongated than in the fifth or seventh pair; the 

 front margin is notched, set with bristles, and finely pectinated; the hind margin is feebly
