Specimens indicative of large ‘cycloid’ Fishes, with teeth of ‘sauroid’ character, have been obtained from the ‘Upper Chalk’ of England. To a species of this kind, with large circular scales covered with minute asperities visible by the aid of a pocket-lens, Agassiz assigned the generic name Pachyrhizodus, in reference to the thickness of the base of the anchylosed teeth.
