the proportion between the length of the fingers and that of the palm being as 4 : 3 ; the palm, 

 one and a half as long as high and as thick as high, is smooth and glabrous. The fingers, 

 that are slightly curved inward like in A. styliceps, shut close together; the dactylus, looked 

 at from above, appears a little narrowed near the base, the v^^idth being here one-sixth of its 

 leno-th. The merus, 1,8 mm. long, appears a little more than twice as long as broad, its 

 o-reatest width being 0,8 mm.; there is a quite rudimentary tooth at the apex of the infero-internal 

 margin. The smaller chela of the female has the same characteristic shape, the palm appears, 

 however, a little less high, the proportion between length and height being as 5:3; the 

 palm is also a little longer in regard to the fingers, the latter being in proportion to the palm 

 as 14: II. The merus, 1,8 mm. long like in the male, is only 0,7 mm. broad. 



Second legs of a stout shape, short, much resembling those of A. styliceps. Merus, 

 in the male, 6-times as long as broad in the middle, carpal joints long: 0,5 mm., 0,8 mm., 

 0,2 mm., 0,2 mm. and 0,4 mm.; chela 0,8 mm. long (palm 0,3 mm., fingers 0,5 mm.). The second 

 joint is 4-times as long as thick, the two following joints are even slightly thicker than long, 

 viz. 0,21 — 0,22 mm. thick. 



In the female the merus has the same form, the carpal joints are 0,52 mm., 0,7 mm., 

 0,22 mm., 0,22 mm. and 0,42 mm. long, chela 0,84 mm. long (palm 0,32 mm., fingers 0,52 mm.). 

 The second joint is little more than 3-times as long as thick, the two following are as thick 

 as long. The second joint appears, in the male, slightly more, in the female slightly less than 

 one and a half as long as the first and the chela is as long as the three last joints taken 

 together. Merus of 3"! legs in the male 3,9-times, in the female 4,1-times as long as broad 

 in the middle, with a tolerably strong, acute tooth at the far end of the posterior margin ; 

 carpus stout, in the male 2,7-times, in the female 2,8-times as long as thick, almost half as 

 long as the preceding joint, its posterior margin armed in the female with one, in the male with 

 two small, movable spinules, long 0,11 — 0,13 mm., and terminating in an acute tooth, while the 

 anterior margin bears 7 or 8 long setae. Propodus 4-times as long as broad, slightly narrowing 

 distally, the posterior margin with 7 spines, proportion between the length of the carpus and 

 that of the propodus in the male 1,42, in the female 1,43; anterior margin of the propodus 

 setose. Dactylus one-fourth of the propodus, slightly curved, with a small, accessory claw 

 on the posterior margin. Merus of 4"^ legs in the male 4,2-times, in the female 4-times as long 

 as broad in the middle, unarmed; carpus with one spinule on the middle of the posterior 

 margin. Third and fourth legs with the ischium u n a r m e d. Eggs large, few in number.
