long, but wide and rounded, its length from mouth greater than dis- 
tance between nostrils, which are nearer snout than angle of the mouth. 
Eye moderate. Teeth their form as in E. lamia, the uj)j)er regularly 
triangular, without notch, narrow in the young, the lower narrowly tri- 
angular, erect, on a broad base, all the teeth distinctly and evenly ser- 
rated. First dorsal beginning at a distance a little less than its own 
base behind the pectorals, and ending at a i)oint a little more than its 
own base behind the ventrals. Height of first dorsal two-thirds the 
depth of the body ; pectoral reaching i^ast first dorsal. Second dorsal 
very small, not one-sixth the height of the first, smaller than anal and 
nearly opposite it. Tail 3^ in length. Color plain light gray. Warm 
seas north to San Diego Bay. 
“Our specimens differ from descriptions of E. lamia in not having 
the first dorsal higher than the body, and inserted close behind the root 
of the pectorals. In E. obscura and E. milherti the upper teeth are 
deeply notched on the outer margin
