five or six articuli, each of which is respectively longer 

 than the articuli of the flagellum, and the first is more 

 than as long again as either of the others. The inferior 

 antennae are scarcely longer than the superior. The 

 first pair of legs are very robust ; the wrist and hand 

 together have the upper margins in form of a continuous 

 curve ; the inferior margin of the wrist is slightly pro- 

 duced between the preceding joint and the hand, and 

 is crowned with several long hairs ; the hand is long, 

 ovate ; the upper margin more curved than the lower ; 

 the palm is continuous with the inferior margin, and 

 defined by a small spine planted upon a tubercle near 

 the carpal extremity, a second spine is placed one-third 

 in advance of the preceding ; the palm is fringed with 

 a row of very minute cilia, and laterally defended by 

 five or six equidistant hairs ; the finger is strong, 

 curved, and sharp. The second pair of legs are long, 

 slender, and membranaceous ; the third joint is longer 

 than the fourth, and the wrist is much longer than the 

 hand ; both these last two joints increase in diameter 

 towards their distal extremity, and are thickly covered 

 with short straight hairs, those upon the hand are more 

 numerous, and altogether prevent the finger from being 

 observed. The walking legs are short and very strong ; 

 the last three pairs are more so than the preceding, and 

 have the scale-like second joints almost disk-shaped ; the 

 fourth and fifth joints are also very broad, the former 

 more so than the latter. The tail is very short. The 

 lateral walls of the last three segments are very deep, 

 especially those of the last joint ; and when the caudal 

 appendages are not extended they are almost covered by 

 them, even when not rolled up. The caudal appendages 

 are free from hairs or spines; their branches are styli- 

 form, with a slight curve gradually tapering to a point.
