Chela of the small cheliped of the male from the Madura-Strait 9 mm. long, nearly one 

 and a half as long as the carapace (9,5 mm.); the palm being 1,06 mm. broad (high) in the 

 middle, the chela appears 9-times as long as broad. The palm that slightly broadens towards 

 the articulation of the fingers, is little longer than the latter, the fingers being 4,3 mm. 

 long, the palm 4,7 mm.; the fingers are more slender than those of the large chela, shut 

 together and the dactylus is Balaemcefls-sha.ped ; the fingers, the pointed apices of which are 

 crossing one another, are of equal length. As regards the granulation and as regards the borders 

 that are entire and fringed with hairs at the inner side, the palm agrees with that of the 

 laro;e chela. 



The small chela of the female resembles that of the male, but the fingers are more 

 slender, shut together and are slightly longer than the palm, while the dactylus is simple, 

 n o t Ba/aeuice/>s-sha.ped. With regard to the length of the carapace this chela agrees with that 

 of the male. In the female from Kwandang-bay the fingers of the small chela are a little longer 

 than in that from Stat. 19. 



The second segment, 8 — 10-times as long as thick, of the slender carpus of the 2 nd legs, 

 is usually but little longer than the first, but in the female from Stat. 19 almost one 

 and a half as long ; the three following segments are of s u b e q u a 1 length, usually, however, 

 the 4 th slightly longer than the two others, but in the female from Kwandang-bay the 

 4 th segment is a little shorter than the 3 rd and slightly longer than the 5" 1 ; the chela measures 

 two-thirds of the length of the 2 nd segment and the fingers are slightly longer than the palm. 



Ischium of 3 ld and 4 th legs with a very small spine at base. Merus of these legs 

 unarmed, those of the 3 rd pair slender, 10-times as long as broad; carpus little more than 

 half as long as the merus, the tapering propodus slender, measuring two-thirds of the merus ; 

 the dactylus, finally, measures little more than one-third of the propodus, is lanceolate, depressed, 

 pointed and appears in the middle much broader than thick. In the legs of the 5 th pair, the 

 carpus is just as long as the merus, while the propodus is a little shorter; dactylus one-third 

 of the carpus, a little more than one-third of the propodus. 



Adult male 28 mm. long, the ova-bearing female 23 or 25 mm.

It is with some doubt that this specimen is referred to A. macrosceles, not only because 

 the legs of the i st pair are missing, but also because it shows some slight differences from the 

 quoted descriptions.
