dc.description.abstract Characteristics of a hybrid, Campostoma anomalum pullum x Luxilus sp. (chrysocephalus, comutus, their hybrid, or a backcross) from the Portage River, OH, were examined and compared with parental species as well as five other Campostoma anomalum x Luxilus cornutus and C. anomalum x L. chrysocephalus hybrids from Ohio, Tennessee, New York, Virginia, and Mississippi. Lateral-line scale count and gill raker count were consistently intermediate in all hybrids. Dentition was intermediate in four of five hybrids, and intestinal diameter was intermediate in both Ohio hybrids. Hybrids for which data were available (n = 5) resembled Luxilus in lacking intestinal coiling around the swimbladder and in liver shape and position (n = 4). Mouth position was intermediate in five of six hybrids. The Portage River hybrid may be a tri-hybrid based on apparent hybridization between the two Luxilus species, L. cornutus and L. chrysocephalus, present at the collection site. en_US
