Abstract
    In the present paper, the brackish-water mudsnail genus Hydrobia is used to assess the degree of anatomical differentiation among cryptic species. Detailed anatomical data for seven populations from four taxa are compared to genetic data in order to test whether there are discrete anatomical differences among taxa, whether it is possible to partition the total anatomical variation into hierarchical among-taxa and among-population components, to find those anatomical characters that statistically discriminate taxa, and to make inferences about the mode of evolution.
