Brama crysoleucas versicolor (De Kay), 



Mouth when closed, on a line drawn through pupil. Scales 

 with 7 to 12 striae. Dorsal depressed, reaching point opposite 

 ninth anal ray. Ventral depressed reaches pointed separated 2 

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

 into orano-e. Other fins lemon-yellow with black lines on caudal 

 and dorsal. Length 7J^ 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 Abramis chrysolciicas 

 roseus Bean,^ from X^ew York City.
