orbital stay not visible externally. Preopercular spines 

 all directed backward, the two uppermost closer together, 

 the two lowermost weak. Opercular spines rather small, 

 sharp, without visible ridges. Mouth nearly horizontal, 

 the tip of the upper jaw nearly on a level with the lower 

 rim of the orbit. Maxillary i\ in head, its posterior end 

 reaching about to vertical from posterior rim of orbit. 

 Lower jaw very slightly projecting, with a slight sym- 

 physeal knob. Teeth on jaws, vomer and palatines, the 

 bands on the latter narrow. Gill-rakers rather slender, 

 2 to 3 in orbit, 23 on anterior limb of first arch. 



Fourth dorsal spine highest, \\\ in head; membrane 

 of first dorsal very deeply incised, reaching only % of 

 the way up on the anterior side of the 3d, and about % 

 of the way up on the 4th spine, nearly to the tip of the 

 1 2th, and about half way up on the 13th spine; soft rays 

 lower than the spines, about x% in the longest spine. 

 Caudal fin truncate, with 11 to 12 full length rays, about 

 if in head. Second anal spine longer and much stronger 

 than third, 2| in head, ij in the soft rays. Pectoral fin 

 reaching to or a little beyond vent, 3^ in length of body, 

 the median rays longest, the 8 lower rays unbranched 

 and thickened; base of fin 3 in its length. Ventrals 

 reaching not quite to vent, the spine about equal to the 

 3d anal spine. 



Scales rather small, those of body, cheeks and inter- 

 orbital space all ctenoid, those on breast cycloid; maxil- 

 lary with minute scales, lower jaw and top of snout naked. 

 Accessory scales few, some of them ctenoid. 



Color: Head blackish above, lips dusky, a dark 

 band from front of orbit forward along side of snout; 

 a dark stripe on maxillary; a blackish or olivace- 

 ous band from preorbital backward and downward 

 across preopercle ; another broader band from posterior
