long, fully as long as the two preceding joints together; the front margin is feebly curved, 

 the hind margin is almost straight, fringed below with some sharp bristles; the hinder 

 lower corner is not produced, rounded, armed with some few bristles, and narrowly hol- 

 lowed for the reception of a part of the front margin of the metacarpus, forming a sub- 

 cheliform organ. The metacarpus is considerably shorter than the carpus, broad at the 

 base, tapering towards the apex, a. little more than twice as long as broad at the base; 

 the front margin is slightly curved, armed with a row of teeth-like spines; on each side 

 of the joint there are two strong bristles. All the joints are densely covered with minute, 

 stout hairs. Within the joints there are well developed glands. The dactylus is stout, 

 curved, more than half as long as the metacarpus; along the hind margin it is closely set 

 with strong, teeth-like spines; at the hind corner of the base there is a perforated heel, 

 as in the preceding species. 



The second pair (PI. VIII, fig. 24 — 26) reach to the middle of the carpus of the 

 third pair. The femur is exactly as long as the three following joints together, inclusive 

 the carpal process; it is much broader at the apex than at the base, scarcely more than 

 twice as long as broad at the base. The genu is a little more long than broad. The 

 tibia is somewhat longer than the genu, narrow at the base, with bulging sides; the hinder 

 loAver corner is nearly rectangular, not produced. The carpus, without the carpal process, 

 is about as long as the two preceding joints together; the front margin is convex, the hind 

 margin a little excavated and armed with stout bristles. The carpal process is well developed, 

 but much shorter than the rest of the joint; the hind margin is almost straight, set with 

 three equidistant, strong bristles; the front side is narrowly hollowed, gouge-shaped, both 

 the edges are closely set with short, spine-like hairs; the outer edge carries also three 

 tolerably long, sharp bristles; the apex of the process is broadly rounded, without terminal 

 spine, but provided with three strong bristles. The front side of the carpal process is only 

 a little longer than half the hind margin of the metacarpus. The metacarpus is broad at 

 the base, tapering, nearly three times as long as broad at the base; the front margin is 

 straight, the hind margin slightly curved, both are closely set with short spines or spine-like 

 hairs; on the hind margin there are also some few bristles; on the outer and inner sides 

 of the joint three very long, strong spines are fixed. The hair-covering of all the joints 

 (PL VIII, fig. 25 and 26) is like that of the first pair. The dactylus is slightly curved, 

 armed at the hind margin with some few, teeth-like spines; it is almost half as long as 

 the metacarpus. Glands as in the preceding pair. 



The third and fourth pairs (PI. VIII, fig. 27) are equal in length and similar in 

 shape. The femur is more dilated than that of the preceding species, scarcely more than 

 twice as long as broad, and somewhat longer than the femur and tibia of the second 

 pair together; the front margin is very convex, the hind margin is straight. The genu 

 is more long than broad. The tibia is much longer than the genu. The carpus is con- 

 siderably longer than the tibia; the hind margin is straight, not serrated. The metacarpus 

 is feebly bent, longer than the carpus, and much narrower. The joints of these pairs are 

 less densely covered with hairs than the joints of the first and second pairs. The dactylus 

 is slightly curved, smooth, scarcely equalling a third of the metacarpus; at its base there 

 is an oblong hole, the outlet for the glands which are present in all the joints.
