two-thirds as long as the metacarpus, and is serrated along the hind margin (PI. XI, 

 fig. 45). Glands are developed, especially in the femur. 



The second pair (PI. XI, fig. 46) are a little longer than the first, and reach to 

 the apex of the carpus of the third pair. The femur is long, somewhat broader below 

 the middle than at the base, and has the margins feebly convex; it is fully as long as 

 the four following joints together; at the lower hind corner there are four or five bristles- 

 The genu is broader than long, with three bristles at the lower hind corner. The lower 

 hind part of the tibia is somewhat more produced than in the first pair, and has the 

 under margins fringed with about twenty long bristles. The carpus is broad, and much 

 produced, the carpal process being almost as long as the stem of the joint; the front 

 margin of the carpus has four bristles at the lower corner; the hind margin is smooth; 

 the front side of the carpal process is gouge-shaped, each margin set with four bristles, 

 and the apex, also armed with four long bristles; the carpal process is two-thirds as 

 long as the hind margin of the metacarpus. The metacarpus is longer than the stem 

 of the carpus, and more than twice as long as broad; the front margin is feebly convex, 

 and carries seven bristles; the hind margin is straight, serrated, with three-pointed teeth, 

 and provided with four bristles; the sides at the joint are also provided with long bristles. 

 The dactylus is more than half as long as the metacarpus, and serrated along the hind 



n. 



The third and fourth pairs (PI. XI, tig. 47). The femur is narrow, almost linear, 

 three times as long as broad, and only a trifle longer than that in the second pair; the 

 hind margin is set with some short, spine-like bristles. The genu is longer than broad, 

 with one spine on the hind margin and another at the rounded hind corner. The tibia 

 is only a little longer than the genu; the front margin is convex, the hind margin straight 

 with some small spines and another longer one at the apex. The carpus is longer than the 

 tibia; the front margin is convex, the hind margin straight, minutely serrated, and pro- 

 vided with some spine-like bristles. The metacarpus is much narrower than the carpus, 

 feebly curved, and quite as long as the two preceding joints together; the hind margin 

 is minutely serrated ; on the sides of the joint there are some short, spine-like bristles. 

 The dactylus is slender, half as long as the metacarpus, and provided with a few slender, 

 very minute spines on the hind margin near the base. 



The fifth pair (PI. XI, fig. 48 and 49) are quite as long as the head, the whole 

 pera3on, and the first pleonal segment together. The femur is narrow, and a little more 

 than twice as long as broad; the front margin is feebly concave, with the lower corner 

 scarcely produced. The genu is longer than broad, with the lower front corner squared. 

 The tibia is a third part longer than the genu, with the margins smooth, and the loAver front 

 corner squared. The carpus is twice as long as the tibia, but a little shorter than the 

 femur; the joint is not dilated as in Euthemisto, but as broad as the tibia; the front 

 margin is provided with very minute, spine-like hairs. The metacarpus is much narrower 

 than the carpus, feebly curved, and considerably longer than the femur; the front margin 

 is minutely pectinated, and provided with short bristles. The dactylus is more than a 

 fourth part as long as the metacarpus, and has a few slender minute spines on the hind 

 margin (PL XI, fig. 49).
