ENNICHTHYS, Girard. 
Gen. Char. —Head of medium size. Mouth large and oblique -, lower jaw projecting beyond the upper. Lips thin ; lower 
one free all round. Premaxillaries slightly protractile. Teeth small, slender, and conical, disposed upon a double series on 
both jaws. Spinous portion of dorsal fin higher than the soft. Anterior articulated rays of anal divided like the rest, and pre¬ 
ceded by three small spines lower than the articulated rays. Scales of moderate development. Lateral line concurrent with 
the dorsal outline. Scales upon the base of caudal and anal. Dorsal groove rather short; sheath formed anteriorly by three 
rows of scales, tapering posteriorly. 
Syn. — Ennichthys, Grd. in Proc. Acad. Nat. Sc Philad. VII, 1855, 322. 
The structure of the dorsal is suggestive of the genus Holconotus, but the presence of a double 
row of teeth on the lower, as well as on the upper jaw, separates altogether both of the genera,
