the merus of the fourth legs appears unarmed: it is, indeed, only by means of the microscope 

 that one observes a trace of an extremely small, rudimentary tooth. The merus of third legs, 

 however, bears a strong acute tooth at the apex. My attention was also drawn by him to a 

 typographical error in the relative measurements of the small chela, the height being 0,72, 

 not 1,72. 



The largest specimen is one from Stat. 152, the specimen from Banda has nearly the 

 same size, while the other specimen from Wunoh-bay is the smallest of all ; all the specimens 

 are of a smaller size than the single individual, long 18 mm., on which this species was 

 established. Except the rostrum the frontal region much resembles that of A. frontalis 

 H. M.-Edw., while the resemblance to A. sttperciliaris Cout. is still greater. The acute 

 triano-ular rostrum that almost reaches to the end of basal antennular article, arises from a 

 protruding part of the front like in these species and at either side of the rostrum the 

 frontal margin runs S-like towards the rounded orbital hoods, that are greatly prominent laterally. 

 Rostral carina compressed, sharp, disappearing at the base of the orbital hoods, from which 

 it is separated by rather deep grooves. Antennular peduncle and stylocerite 3iSm A. siiperciliaris. 

 Carpocerite extending beyond the tip of the antennular peduncle by half the 3''^ article; the 

 terminal spine of the scaphocerite extends, in the largest specimen from Stat. 152, almost to 

 the end of the antennular peduncle, while the narrow blade reaches to the 2'^'^ third part of 

 3"i antennular article, in the younger specimen to the end of median article. 



As is proved by the measurements, the telson appears in the youngest specimen 4-times, 

 in the two other ones 3,6-times as long as the posterior margin is broad and in the still 

 larger type specimen of the typical species 3,27-times: the telson probably therefore not differs 

 from that of the typical species. Posterior margin as in A. S7tperciliaris, outer angles acute, 

 not prominent, spinules of the upper surface situated near the lateral margins. 



Except in the largest specimen, both chelipeds are present; in the male from Banda 

 the larger cheliped is situated at the left, in the other specimen at the right side. Merus of 

 the large cheliped of the Banda male stout, twice as long as the outer surface is broad, the 

 infero-internal margin terminates in a small, acute tooth, while the upper margin ends in a 

 compressed tooth, that appears acute in a lateral view, but rather obtuse, when looked at 

 from above. Relative dimensions of the chela: fingers i; total length 3,3 or 3,4; height 1,27. 

 The chela therefore seems to agree with that of the typical species, dactylus as in A. ovaliccps^ 

 but the tip distinctly truncate. 



In the male from Banda the large chela is 2, 5 -times as long as the other. Merus of 

 small cheliped not shorter than that of the large, but it is 2, 5 -times as long as broad; infero- 

 internal margin unarmed, upper margin as in the merus of the other cheliped. The smaller 

 chela seems also to agree with that of the typical species, its relative dimensions are : fingers i , 

 total length 2, height 0,64 and the fingers show exactly the features of A. Stanleyi. Merus 

 of second legs in the male from Banda 6,6-times, in the younger specimen from Stat. 152 

 5,7-times longer than wide, appearing in the latter less slender. In the Banda male the carpus 

 is 1,36-times, in the younger specimen from Stat. 152 1,28-times as long as the merus; in 

 the Banda male the carpal segments are 0,9 mm., 0,8 mm., 0,28 mm., 0,28 mm. and 0,46 mm.
