Fig. 9. 



Head 2.5; depth 2.9; scales in lateral line 26. D. V-I, 10; A, II, 8. Eye 3.5; 

 snout 4.3; interorbital width 3.8 in head; maxillary 2. Body moderately compressed, 

 dorsal and ventral outlines similar. Caudal peduncle 1 very long, deep and com- 

 pressed, its least depth \ the greatest depth of the body. Teeth small, conical, 

 recurved, in narrow bands; anterior teeth in upper jaw somewhat enlarged, teeth 

 present on vomer and palatines. Pectoral fin 1.7 in head, reaching beyond tips of 

 ventrals and not quite to origin of anal; ventral 2; soft dorsal and anal similar, high, 

 somewhat falcate; first dorsal spine the highest and strongest, 2.2 in head, second 

 dorsal 1.7, anal 1.8; caudal emarginate, the lobes blunt, 1.6 in head. 



Color in spirits, brownish; caudal dusky, narrowly tipped with pale; central 

 rays of spinous dorsal blackish, contrasting sharply with the rest of the fin; other 

 fins pale. The black center of the spinous dorsal is the only distinctive color mark. 

 It appears to be closely related to A. atrodorsatus (Heller and Snodgrass) from the 

 Guadalupe Islands, but differs in color markings of vertical fins and m proportions, 

 and to A. atricaudus (Jordan & McGregor) from the west coast of Mexico, from 

 which it differs in the structure and color of the dorsal fin.
