In the course of the preparation of the second part of the Catalogue of the Marine Reptiles of the Oxford Clay in the Collection at the British Museum, it has been necessary to examine in detail the structure of the skull and mandible of the Pliosaurs, especially of Peloneustes philarchus, several excellent specimens of which are included in the Leeds Collection. In the course of this examination several peculiarities have been observed, which on the one hand tend to reconcile the conflicting views as to the structure of the skull roof that have been put forward, and on the other serve to correct the interpretation of the elements of the mandible given in the first part of the Catalogue.
