Iclithyosaurus platyodon from the Lias at Lyme Regis, discovered by T. Hawkins, Esq. and deposited in the British Museum, together with all the other splendid fossil remains that are engraved in his memoirs of Ichthyosauri and Plesiosauri. This animal, though by no means full grown, must have measured twenty-four feet in length. The extremity of the tail, and left fore paddle, and some lost [021] fragments of the rest of the skeleton, are artificially restored. (Hawkins.)
