Summary

1. Thirty-six species of Foraminifera are recorded from various localities in the Hartwell Clay and associated beds. 2. The assemblage of species is characterized by:— (a) the abundance of rotulate Cristellarians of Lower Cretaceous type, and of Cristellaria fragraria. (b) the common occurrence of Vaginulina harpa, a Jurassic type. (c) the rarity of arenaceous, and the absence of porcellanous forms. 3. The Foraminifera from the Hartwell Clay are compared with those from other deposits in the Aylesbury district, and with those from foreign deposits of similar age. 4. The relative abundance of glauconite is a point of similarity between the Hartwell Clay and beds hitherto regarded as Kimmeridge Clay.
