Abstract:Three additional specimens of the hybrid combination Noturus gyrinus x N. miurus are described. Morphologically, they are similar to those previously reported by Trautman (1948) and Taylor (1969), being generally intermediate between the parental species. Hybrid vigor is indicated in one individual by its large size and robustness. All four specimens are females but only the largest appears to have been capable of reproduction. Ecological observations suggest that a combination of factors, including perhaps submarginal habitat and unequal numbers of the parental species, resulted in mismating to produce the hybrids. Madtoms may lack ethological barriers to hybridization which is characteristic of other ictalurids.
