Mantell Collection. 2276. The imperfect right hyoplastral apparently belonging to the 'ig.) same individual as the preceding specimen; from Cuck- field. Figured in the accompanying woodcut in connec- tion with the latter. The vermiculated character of the sculpture, especially on the lower half, is well shown. Mantell Collection. R. 658. The imperfect left hyoplastral; from the Lower Wealden (Tilgate Grit) of Battle, Sussex. This specimen has lost the anterior extremity, but shows the median suture and the commencement of the incision for the entoplastral, as well as part of the sulcus formed by the division between the gular and pectoral shields. The vermiculated nature of the sculpture is very clearly shown, and clearly distin- guishes the specimen from the hyoplastrals of T. punc- tatum. Presented by J. E.
