The Middle Jurassic (Bajocian) Grey Limestone Series of Yorkshire is shown to have been deposited in a broad embayment, transgressing deltaic sediments of Bajocian age, and is here divided into two ostracod faunal zones: a lower zone of Glyptocythere polita and an upper zone of G. scitula, the type section being at Hundale Point. The zone of G. polita is present only towards the centre of the basin and represents the first phase of the marine transgression. The facies changes within the Series are produced by intermittently rising sea-level and the repeated southward extension of the northern delta. Shore-line sediments are also identified. Fourteen stratigraphical sections are described in detail. The period of marine deposition is considered to have taken place approximately during sauzei to blagdeni times and is thus in part at least equivalent to the Coronaten-Schichten of N.W. Germany. The ostracod fauna of the Grey Limestone Series is described for the first time. Four genera: Caytonidea, Cloughtonella, Malzia and Mesocytheridea are new. Sixteen new species and one new subspecies are also described. The palaeoecology of the ostracod fauna is briefly mentioned.
