Fescadillo del Bey. 
(Girard, Pros. Acad. Nat. Sci. Phila. IBal, l:>4: tyi^e Atherinopsis caViforniemis Grd.) 
This gjenus differs from Menidia in the non-jn’otractility of the upper 
jaw. The spines of the i)reinaxillaries are very short, much shorter 
than the eye, and they are covered by a skin which is continuous with 
that of the forehead, beings only capable of such motion as is permitted 
by the extension of a fold of skin between the jaws and the frontal 
region. Species reaching a comsiderable size and having importance as 
food-fishes. {aO-:pc'.>rj, Atlieriua; appearance.)
