They were emphatically rulers in every department of Nature—rulers of the sea, of the land, and of the air. We shall treat of them under the three heads thus indicated, viz.: 1. Enaliosaurs (sea-saurians), or rulers of the sea; 2. Dinosaurs (huge saurians), or rulers of the land; and, 3. Pterosaurs (winged saurians), or rulers of the air. The first were wholly swimming, the second walking, the third flying, saurians. Intermediate between the first and second was a fourth order, the Crocodilians, which both swam and crawled. 1. Enaliosaurs.—From the immense variety of these we select only two for description as representative genera, viz., Ichthyosaurus and Plesiosaurus (Figs. 683 and 684). The Ichthyosaurus (fish-lizard) was a huge animal, in some cases thirty to forty feet in length, with a stout body, short neck, and enor- mous head, sometimes five feet long, and jaws set with large conical, striated teeth, sometimes 200 in number. The enormous eyes, some- times fifteen inches in diameter, were provided with radiating, bony plates (sclerotic bones), as are the eyes of birds and some living and</i><br><br><b>Note About Images</b><br></p>
