of head. Pectorals and pelvics subequal, a little more than ^ 

 length of head. Caudal rounded. Dark brownish. 



A single specimen, 230 mm. in total length. 



This species is very closely related to A. cinctus GUnth. from 

 Norfolk Island, described from a specimen of nearly the same 

 size. Comparison shows that A. cinctus differs in the larger head 

 (2|- in the length), higher dorsal fin (longest spines i the length 

 of head), longer second anal spine (| the length of head), longer 

 and stronger maxillary (extending to below posterior | of eye, its 

 width g the diameter of eye), and the banded coloration.
