Pale, but not translucent; sides with a broad silverj' shade, but with- 
out distinct stripe. Body slender, moderately compressed, the belly 
carinate and faintly serrate. Head comiiressed, conic, the snout rather 
pointed, bluntish at tip. Maxillary exteuding beyond root of mandible. 
Eye not very large. Teeth in both jaws. Pectorals and veutrals short. 
Head 3.J ; depth 5. A. 22. Southern California; abundant. Very 
likely the young of 8. ringens, from which it seems to be separated by 
the more compressed body. The many specimens obtained by us at 
San Diego were of the same size, and schools of immature anchovies, 
uniform in size, are rarely seen.
