This species differs from A. Alcyone de Man = aatleipes Cout. in the main by the 

 following: 1° There is a distinct spine on the basicerite, though rather short (not lono-, as 

 stands in Coutiere's description), 2" the shape of the smaller chela, especially in the male the 

 dactylus being distinctly broadened and, like in the female, just as long as the palm, 3" by 

 the first carpal segment of the 2°^^ legs being longer in proportion to the 2°*^ and hardly 

 shorter than the 5'^, 4° by the merus of the 3''^ legs bearing no spinules on the inner posterior 

 margin, 5° by the merus of the 4"^ legs presenting also a subapical tooth, though usually 

 smaller than that of the 3'''^ and 6° by the 6* abdominal somite bearing a couple of small 

 teeth in the middle of the posterior margin. 



The specimen from Stat. 33 is one of the smallest of the 28 that were collected and 

 4 mm. long. The carpal segments of the second legs are 0,2 mm., 0,35 mm., o,i mm., 0,1 mm. 

 and 0,22 mm. long; the chela is 0,54 mm. long (palm 0,24 mm., fingers 0,3 mm.), as lono- as 

 the two first segments taken together. Carpus of the 3'''^ legs with two spines, that of the 4'^^ 

 with one on the posterior margin, besides the terminal spine. 



In the largest specimen from Stat. 49=*, a male long 14,5 mm., the carpal segments are 

 0,65 mm., 1,6 mm., 0,36 mm., 0,4 mm. and 0,7 mm. long, the chela is 1,26 mm. long (palm
