In 1894 Mr. W. A. Sanford described, in the Proceedings of the Somerset Archaeological Society (vol. xl, 1894, p. 234), the geological circumstances of the discovery of a large fossil reptile. The fossil bones were found by the Eev. Sydenham H. A. Hervey and himself in the Rhætic beds in the parish of Wedmore, in the Vale of Glastonbury; and compared to Megalosaurus in its large size and carnivorous character. The remains were generously presented to the British Museum (Natural History) at South Kensington. I have now to redeem a promise made by Mr. Sanford in his paper that I would name and describe the specimens.
