i The figures represent the number of times the former is contained in the latter, respectively. Note that in the few specimens 
measured, which were taken at random except that specimens of approximately like size were taken for the purpose of comparison, 
there are no overlapping individuals for one ratio and a significant divergence for the other. 
The data and conclusions presented above may now be summarized in the 
conventional form used in descriptive works.

North Carolina 
Cynoscion nothus (Holbrook) 
Common name— Silver squeteague. 
Other common names— Bastard trout (Chespeake Bay and coasts of North 
and South Carolina); sand trout (Texas coast, where it is not distinguished from 
Cynoscion arenarius ) .
