JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 



247 



middle of eye, 2 in head; lower jaw barely longer than upper; snout equal in length 

 to eye; preopercle finely serrate on both limbs; no canines present. 



Third and fourth dorsal spines subequal, half length of head; spine of soft 

 dorsal 2.125 in head, its first two rays equal to post-orbital part of head. Anal 

 inserted under second soft ray of dorsal, second spine 3 in head. Pectoral reaching 

 nearly to anal, as do ventrals; caudal emarginate. Scales finely ctenoid, rather 

 loose; lateral line as usual. 



Color nearly uniform, pattern lacking, save for an indistinct, small caudal spot; 

 ventrals and spinous dorsal dark, latter black at tip. All other fins somewhat dusk}'. 



This species is apparently most closely related to Anna nigra (Doderlein) from 

 which it differs in its longer spines, its soft dorsal and anal, longer pectorals, shorter 

 maxillary, and lighter color of anal, ventral, and soft dorsal fins.
