Fig. l. Fossil Crocodilean found at Saltwick near Whitby, eighteen feet long, and preserved in the Museum of that town. This figure is copied from Plate XVI. of Bird and Young's Geol. Survey of the Yorkshire coast. As this appears to be the same species with that engraved in the Phil. Trans. 1758, Vol. 50. Pt. 2. Tab. 22. and Tab. 30, and presented to the Royal Society by Captain Chapman, Mr. König has applied to it the name of Teleosaurus Chapmanni.
