This report catalogues the single-mount ostracod specimens of late Jurassic age (Kimmeridgian and Portlandian) held in the collections of the British Geological Survey. The collection includes type and figured specimens, but the majority of the specimens comprise the stratigraphical reference collection, which forms the basis of a number of publications and internal reports. The reference collection currently contains 224 specimens, comprising 26 genera (one being retained in open nomenclature) and 74 species (of which 8 are left in open nomenclature). The assemblage slides from which the single mounts were made are also held in the palaeontological collections of the British Geological Survey.
