N2  - Electrophoretic and morphological comparisons were made between 14 populations representing the major part of the known range of the nominal fish species, Pseudomugil signifer Kner and Pseudomugil signatus (Gunther), described from the fresh and brackish waters of eastern Australia. Analysis by principal components was used to assess the morphological data. .Clinal variation revealed in 10 morphological characters and at two enzyme loci was found to bridge most of the previously described differences between species. The type material of P. signatus afinis from the Low Isles, Queensland, was re-examined and did not appear to differ morphologically from the coastal species. It is therefore suggested that the populations studied represent a single species Pseudomugil signifer Kner.
