1. 1. Differences in muscle proteins of the species and subspecies of the genus Xiphophorous are discernable by means of paper electrophoresis. 2. 2. The lower limit of differentiation was found at the subspecies level, as the microevolutionary divergences of isolated populations of the species maculatus could not be detected with this method. 3. 3. The electrophoretic data parallel the independently established taxonomic division of the genus Xiphophorus into three species groups. Thus, there are two extreme pattern groupings and one intermediate for both species groups and muscle proteins.
