Body rather elongate, fusiform, little compressed; curvature of 

 dorsal and ventral outlines nearly equal. Head short, broad, inter- 

 orbital broad and flat, outline from tip of snout to base of dorsal 

 nearly straight; ej^e.very large, equal to snout and interorbital ; 

 mouth large, oblique, lower jaw projecting; maxillary reaching to 

 vertical from anterior border of pupil ; villiform bands of teeth on 

 jaws, an outer row of enlarged blunt, canine-like teeth in each jaw; 

 preorbital narrow, equal to diameter of pupil; vertical border of 

 preopercle concave, angle acute, ending in a long spine, projecting 

 backward and upward; free margin everywhere armed with strong 

 denticulations ; gillrakers slender. 



Spinous dorsal triangular, fourth spine longest, 2 in head; soft 

 dorsal low ; caudal truncate ; second anal spine very long and strong, 

 longer than third ; anal spine and rays 2.25 in head ; ventrals mod- 

 erate, tips reaching half-way from base to first soft ray of anal, 1.5 

 in head; pectoral nearly as long as head, slightly falcate; base of 

 pectoral below level of eye ; scales moderate, regular in arrangement, 

 the rows of scales above lateral line parallel with it.

This individual agrees in all essential characters with the types, 

 U. S. Nat. Mus. No. 17546, of this species. The coloration is much 

 darker and the outer row of teeth larger than in the types, similar 

 to Conodon nohilis. This species has been previously recorded only 

 from Lower California.
