The bronchial sacks are attached to the third to sixth pairs of peraiopoda. They 

 are smaller in the female than in the male. In the male those of the fifth and sixth 

 pairs are the longest, but not half as long as the femur. 



The ovitectrices are large, smooth, attached to the second to fifth pairs of pera?opoda. 



The first pair of perosopoda (PI. II, fig. 4) are the shortest of all. The femur is 

 very long, narrow, linear, much longer than all the following joints together (5 : 3), fhe 

 hind margin is straight. The genu is smooth, almost cubical. The tibia is scarcely 

 longer than the genu, the lower hinder corner produced, carrying three or four short 

 bristles. The carpus is as long as the two preceding joints together, considerably broader 

 below; the lower hinder corner is not produced but armed with a strong spine; the under 

 margin is perfectly straight, fringed with a row of short sharp bristles; the anterior and 

 posterior margins are sligthly convex. The metacarpus is almost as long as the carpus, 

 feebly bent, tapering toAvard the apex, Avith a short bristle at the apex. The dactylus 

 is pedunculated, with a short, sharp tooth at the hinder side, projecting from the peduncular 

 part of the joint. All the joints are provided Avith glandular masses, but I have not 

 been able to find any outlet for the glands. 



The second pair (PI. II, fig. 5 and 6) are longer than the first. The femur is a 

 little longer and narrower than in the first pair, linear, in the male as long as, in the 

 female longer than all the folloAving joints together. The genu is a little longer than 

 broad, longer than the tibia; both joints are totally smooth; the loAver hinder corner of 

 the tibia is not produced. The carpus is long, narroAv, linear, longer than a third of 

 the femur, smooth. The metacarpus is a little shorter than the carpus, and narroAver, 

 linear, the apex projects into tAvo thin, holloAved processes, fringed with hairs; these pro- 

 cesses reach a little farther than half the dactylus. The dactylus is robust, pedunculated, 

 Avith an appendicular tooth at the hinder side. The dactylus equals about a fourth of 

 the length of the metacarpus. In all the joints there are richly developed glandular 

 masses. 



The third and fourth pairs are equal in length and similar in shape. The femur 

 is narrow, linear, in the female as long as the three following joints together, in the male 

 a little shorter. The genu is scarcely longer than broad; the tibia is almost tAvice as 

 long as the genu, both joints smooth. The carpus is almost tAvice as long as the tAvo 

 preceding joints together, linear, fringed Avith some short, equidistant bristles along the 

 hinder margin. The metacarpus is shorter than the metacarpus of the fifth and sixth 

 pairs and a little shorter than the next preceding joint, tapering, feebly curved, and totally 

 smooth. The dactylus is scarcely as long as a fourth of the metacarpus, pedunculated, 

 feebly curved, Avith a heel at the hinder corner of the base; in this heel is an oblong 

 aperture for the outlet of the glands Avhich fill all the joints. 



The fifth and sixth pairs are equal in length as long as the two preceding pairs, and 

 a little longer than the perseon. The joints are similar to those of the tAvo preceding pairs, 

 except that the metacarpus is a little longer; all joints filled with glands. 



The seventh pair (PI. II, fig. 7 and 8) are considerably shorter than the sixth pair, 

 reaching scarcely farther than to the apex of the carpus of that pair. The femur is 

 narroAv, feebly curved, only a little shorter than all the folloAving joints together, but
