and more or less crowded forwards, but often showing various irregulari- 
ties in arrangement, about 43 (39-45) ia a longitudinal series and 15 
(14-10) in a transverse series between the ventrals and the dorsal. Fin- 
rays somewhat variable, the dorsal with 11 (10-13) develoi^ed rays, the 
anal with 7, and the ventrals with 9 (rarel^'S). Coloration varying with 
age; never distinct series of black spots along the rows of scales. 
Young with a broad black lateral band, bordered above by paler. In 
some specimens from clear waiter this band is of a jet-black color and 
very distinct ; in others it is duller. Later this band becomes broken 
into a series of blotches, which often assume the form of broad trans- 
verse bars. In adult specimens these bars disappear, and the color is 
nearly uniform brown, dusky above, paler below, everywhere with a 
coppery or brassy, never silvery, lustre. The fins are dusky or smoky 
brown, rarely reddish-tinged. Sexual differences strong. The males 
in spring wnth usually three large tubercles on each side of the snoilt, 
and with the anal fin more or less swmlleu and emarginate. Adult 
specimens with the back gibbous and the body strongly compressed, 
in apiiearance quite unlike the young. Maximum length about 10 
inches. New England to the Eocky IMountains, south to Texas ; very 
abundant.

Body oblong, the back more elevated, the body deeper and more com- 
liressed than in the preceding, the greatest depth in advance of the 
dorsal fin being contained about 2f times in the length. Nape less gib- 
bous than in E. sucetta. Head quite small and short, the large eye 
being almost exactly midway in its length. Its length 41 in that 
of the body. Eye 4^ in head. Interorbital space rather narrow, 
transversely convex, less than half the length of the head. Mouth 
small, x)rotractile forwards, the lower jaw oblique ; lips as in the i)re- 
ceding. Scales large, much larger and much more uniform in their 
imbrication than in E. sucetta^ 3G in a longitudinal series, and about 
13 in a transverse series from the ventrals to the dorsal. Dorsal fin 
high, of 13 developed rays; anal moderate, wdth 7; ventrals large, 
with 10. Color dark olivaceous above ; each scale along the sides re- 
flecting i^ale from the strongly striated middle part, these giving in cer-
