title: Allozymic and morphological differentiation among three South American frogs, genus Eupsophus (E. roseus, E. insularis and E. contulmoensis).
abstract: 1. Three species of the frog, genus Eupsophus, were examined using electrophoresis at 21 loci, and nine morphological characters employing discriminant and principal components analyses. 2. The allozymic and morphological differentiation patterns do not agree. 3. It is suggested that selective pressures are responsible for the incongruence of both sets of characters.
