    A genetic and morphological analysis of species complexes within the genus Patella
    (1998) Ridgway, Tyrone Melville; Branch, George M; Cook, Barbara
    Limpets of the genus Patella are very common intertidal molluscs that have a widespread world-wide distribution. Despite this, the systematics of the genus is still in a state of confusion. However, in comparison to other regions, the southern African representatives of Patella are fairly well characterised. Nevertheless, some long-standing taxonomic uncertainties still exist for certain of the southern African species. This thesis combines both morphological and genetic techniques to solve these uncertainties.
