This study used an extensive list of nearly one hundred morphometric measurements in size-corrected multigroup principal component and discriminant functions analyses, in an attempt to separate species from species complexes within the catshark genus Smith, 1837 (Chondrichthyes: Scyliorhinidae). (Gmelin, 1789) was readily discriminated from (Smith in Müller & Henle, 1838), but the putative taxon Fowler, 1934, could not be separated from These results support the hypothesis that there are two valid species within the genus and and that is a junior synonym of Being the first in a series of shape variation analyses by the author, a comprehensive description of the methodology is given.
