The mid-lateral band (which is dark and discrete in _C. erythrogaster_, but faint, broad, and diffuse in _N. c. frontalis_) is broader and fainter in the hybrids than in _Chrosomus_, but is better developed than in _N. c. frontalis_. The dorsolateral dark band of _C. erythrogaster_ is present in the hybrids, but is less distinct than in that species, and less distinct than the mid-lateral band of the hybrids themselves. The dorsolateral band is not present in _N. c. frontalis_. The color of the peritoneum in the hybrids is the glossy, jet-black of _C. erythrogaster_ in two specimens, and the dusky-black of _N. c. frontalis_ in one.
