Brama crysoleucas versicolor (De Kay). 
Mouth when closed, on a line drawn through pupil. Scales 
with 7 to 12 striz. Dorsal depressed, reaching point opposite

scales from vent. Ventral fins crimson on anterior rays, fading

and dorsal. Length 7% inches. Delaware River. (Abbott.) 
Provisionally this may be retained. It is evidently close to the 
common roach and apparently best distinguished by the crimson 
ventrals. Perhaps it is identical with Abrams chrysoleucas 
roscus Bean,! from New York City.
