Detailed morphological studies were made of 78 specimens of Carpiodes cyprinus, 51 C. velifer, and 104 C. carpio for the purpose of finding additional morphological criteria for identifying these species in the field. The various ratios and counts were highly variable and overlapping and no new criteria were found.
