Station 5S. Anchorage off Seba, Savn. 



A species, probably of small size, of the group „breri- 

 ro-stris" de M., closely related to A. puhescens n. sp., from 

 which it differs by the following: 



Carapace not pubescent, almost glabrous. Eostrum just 

 as long as broad at its base, rostral carina rather sharp 

 between the orbital hoods, almost indistinct posterior to 

 them. Stylocerite not spiniform at its extremity, which is, 

 however, acute, curved inward and reaches to the distal 

 sixth of the visible part of 1=' joint. 



Palm of larger chela one and a half as long as the 

 fingers, outer margin of lower border rounded, for the 

 rest the chela resembles that of A. pubescens. 



Merus of smaller chelipede of the male stouter, 2,3-time3 

 as long as broad, chela distinctly shorter than the carapace, 

 stouter, only 3-times as long as high, upper border with- 

 out a transvei^ groove, fingers slightly longer than the
