those of the hind margin; on the sides of the carpal process there are some short hairs. 

 The metacarpus is broader than the carpal process, broadest at the middle, scarcety twice 

 as long as broad; the hind margin is almost straight, armed with two smaller and three 

 larger teeth, serrated at their bases, the denticles in the serration are very unequal 

 in size; at the under margin there are one large, serrated tooth, and three minute den- 

 ticles behind the dactylus; in front of the dactylus the anterior corner of the metacarpus 

 is produced into two strong, spine-like processes; above these processes there are three 

 teeth on the lower half of the front margin of the metacarpus. The dactylus is stout, 

 curved, very broad at the base, much longer than half the length, and longer than the 

 breadth of the metacarpus. Just at the base of the dactylus on the hind side there is 

 a small, oblong aperture for the outlet of the secretion of the glands, which are to be 

 seen within the carpus and metacarpus. A little below this aperture the hind margin of 

 the dactylus is armed with four to five minute denticles. The length of the whole leg 

 is 6,r> mm. (spec. B.), or 7 mm. (spec. A.). 



The second pair (PI. Ill, fig. 8 and 9) are about a third longer than the first pair, 

 and nearly half as long as the third pair. The femur is nearly twice as long as the 

 femur of the first pair, and much longer than the four following joints together; along 

 the front margin there are six alternating short and long teeth, on the hind margin there 

 are eight to nine broad teeth, unequal in size; the lower hinder corner of the joint is pro- 

 duced into a sharp tooth. The genu is much broader than long, the hinder lower corner 

 produced into a long, spine-like tooth, above this there is a smaller tooth on the hind 

 margin. The tibia is similar to that joint in the first pair. The front margin of the 

 carpus is feebly curved, totally smooth, much shorter than the front margin of the meta- 

 carpus; on the outer side of the joint runs a low ridge, armed with three broad teeth, 

 the inner margin is smooth. The carpal process is much longer than the rest of the joint, 

 the apex forming a long, sharp tooth; the hind margin is armed with five broad teeth, 

 finely serrulate at their bases as in the first pair; the front margin has seven to eight 

 unequal teeth, serrulate; the front margin is somewhat longer than the hind margin of 

 the metacarpus; on the sides of the carpal process there are some few scattered hairs. 

 The metacarpus is more than three times as long as broad; the front margin is straight 

 above and smooth, the lower part is curved, armed with two very small teeth, the lower 

 corner is produced into two strong, spine-like teeth; the hind margin is provided with 

 nine broad, unequal, serrulate teeth; the under margin is armed with one strong, narrow 

 tooth, and one or two smaller ones. The dactylus is broad at the base, feebty curved, a 

 little longer than in the first pair, but shorter than half the metacarpus; as in the first pair 

 it exists an aperture at the base of the dactylus for the outlet from the glands, which 

 occupy the interior of all the joints. The length of the leg is 10 mm. (spec. B.), or 11 

 mm. (spec. ^4.). 



The third pair are more than a third shorter than the fourth pair. The femur is 

 as long as the three following joints together, linear, narrow, not broader than the follow- 

 ing joints, except metacarpus; the front margin is smooth; on the hind margin there are 

 eleven or twelve sharp teeth. Te genu is very short, with two teeth on the hind margin,
