PALEONTOLOGY From the Oxford Clay of Bedford the late Professor J. Phillips described the fore-limb of a long-necked plesiosaurian under the name of Plesiosaurus eurymerus. The species, of which nearly perfect skeletons have subsequently been obtained from the same formation in Huntingdon- shire, is characterized by the great width and shortness of the upper bone (humerus) of this limb, and is now known as Cryptoclidus eurymerus. Another plesiosaurian, Peloneustes pbilarchus, which is nearly related to P/iosaurus, is represented in the Oxford Clay of the county by an imperfect skeleton (now in the British Museum) from Kempston. Finally, an imperfect dermal spine in the same collection from the Oxford Clay of Bedford indicates the occurrence of an armoured dinosaur probably belonging to the genus commonly known as Omosaurus. 35
