Abstract

The five species of Clinocottus occur in intertidal habitats along the Pacific Coast of North America. Genetic variation among these species was ex- amined to determine the evolutionary relationships within the genus. Allelic fre- quencies at nine protein-encoding loci were surveyed using starch gel electropho- resis. These loci were either polytypic or polymorphic among the taxa examined. The five species of Clinocottus shared alleles at 46% of the loci examined. In contrast, a closely related species, Oligocottus maculosis, shared alleles with Cli- nocottus at 27% of examined loci. Phenetic and cladistic analyses support Bolin's (1 947) analysis of the evolution of the genus, yielding a phylogeny that is congruent with his scheme based upon external morphological characters.
