Related to the chub and roach, it differs in the same respects 
from the other Leuciscine in the presence of at least 5 teeth 
in the larger pharyngeal series. From the chub it differs in 
the absence of a maxillary barbel at all ages, and from the 
roach in having the postventral region rounded, that fish hav- 
ing it compressed to a sharp keel over which the scales do not 
pass. It has a wide mouth and small scales, and the males are 
brilliantly colored with red pigment during the breeding-season. 
I have not seen examples from the Delaware among the multi- 
‘tudes of cyprinoids which [ have examined from its various 
affluents. The examples Dr. Abbott records were stated by that 
gentleman to have been sent to Cope and by the latter to have 
been determined as Clinostomus funduloides. ‘They were taken ° 
in the main channel of the river at Trenton.
