 1, 9 ; scales 63 ; snout 3| in head, longer than eye ; maxillary to below middle 

 of pupil, 2\ in head; lower jaw projecting; depth of head over hinder mar- 

 gin of eye, If in its length. A single large canine in front of upper jaw, 

 4 or 5 small teeth on side of lower jaw, other teeth few and small; 

 tongue free at end and sides, with a broad median groove; slit of ])Oste- 

 rior nostril nearly vertical. Gill rakers 3+7, the longest \ eye. Opercu- 

 lar flap extending beyond upper base of pectoral; preopercle with a 

 membranous margin. Dorsals contiguous; membrane of anal scaled 

 almost to tii>, that of dorsal about halfway. Scales weakly ctenoid, 

 those on top of head irregular in size. Pectorals about e(]ual in length 

 to ventrals, 1^ in head; caudal doubly concave, middle rays longest. 

 Curve of lateral line gradual, becoming straight behind the fourth dorsal 

 ray. Color in alcohol, very dark olive above, the entire sides with golden 

 luster, paler below; dorsals, pectorals, and caudal lightly punctate,
