the distal extremity of the carpus. The fingers are 

 four fifth or three fourth of the length of the 

 palm and meet along their inner edges when closed. 

 The dactylus , examined with a lens , presents two small 

 teeth near the articulation, the first of which appears 

 double , the second conical ; the immobile finger is also 

 armed with a small conical tooth , placed between the 

 two opposite teeth of the dactylus. Like in the other 

 allied species on each finger a sharp cutting-edge runs 

 between the second tooth and the tip. These legs are 

 covered with minute points , those on the inner margin of 

 the joints are a little larger , appearing here as sharp 

 thorny spinules , directed forewards ; the fingers are nearly 

 smooth. The latter are covered with rather close 

 hairs on each side of the basal teeth and of their cutting- 

 edge , until slightly beyond the middle of their length ; 

 for the rest the second pair of legs are glabrous. 



The second pair of legs of a younger male, which is 47 mm. 

 long , are comparatively a little shorter , measuring two 

 thirds the length of the body : they are also less stout 

 and thinner than the described legs of the adult male. 

 The merus does not reach the tip of the antennal scales, 

 so that only three fifth of the carpus project beyond 

 it; it measures also ^j- the length of the whole leg. The 

 carpus, again nearly once and a half as long as the merus, 

 is almost as long as the hand, not shorter as is 

 the case in the adult male. Its diameter at the distal end 

 measures scarcely ^/u of its length. The fingers have exactly 

 the same length as the palm and are not yet covered 

 with hairs , but the teeth are already developed (Fig. Ig). 



Finally, the second pair of legs of a quite young male which 

 measures only 33 mm., are but half as long as the body. 

 The merus projects scarcely beyond the antenoal peduncle 

 and measures again one fifth of the whole leg. The carpus 

 is only a third longer than the preceding joint and, accu- 

 rately measured, proves to be slightly longer than 

 the hand, as in Pal. Ritsemae', its diameter at the distal
