N2 - The first record of a natural intergeneric hybrid of Campostoma anomalum × Rhinichthys atratulus is described from the Youghiogheny River drainage. Morphometric and meristic characters of the parents and hybrid were used to calculate a mean hybrid index value of 49.8. Dentition of the hybrid was intermediate as was intestinal coiling. In addition to the hybrid index, C. anomalum, R. atratulus and the hybrid were examined electrophoretically. Of the 32 enzymatic loci resolved, six (ADH-A, EST-B, LDH-A, PGM-A, SDH-B and SOD-C) showed hybrid inheritance patterns identical to the enzyme pattern obtained by mixing tissue extracts composed of the two parental species.
