They are characterized by the prismatic, slightly curved form of the crown, the presence of from two to four longitudinal ridges on the enameled face, and the serrated margins and summit. The teeth of the upper jaw are curved in the opposite direction to those of the lower, and have their convexity external. From the Wealden clay of Sussex, England. No. 60. [1393] Iguanodon Mantelli, Meyer. Left Hind Foot (cast). The Iguanodon had large hollow limb-bones and un- guiculate feet, the hind pair having only three well developed toes. The small manus had five functional digits. This unique speci- men was found associated with the undoubted leg bones of this great her- bivorous reptile in the Wealden of the Isle of Wight, and has been pro- nounced by Prof. Owen to be the foot, probably hind foot, of a young Iguanodon. Size, 24 x 12. No. 61. [191] Brontozoum giganteum, Hitchcock. Single Track, on slab (cast). This is the largest tridactyl impression ever discovered, although many thousands of "Bird-tracks" are found in the Triassic rocks, especially in the val- lej' of the Connecticut. It measures eighteen inches in length, embracing an area of thirteen inches square with- in its outlines, and is capable of holding two quarts of water. The print is remark- ably well defined, having all the fidelity of a plaster cast. Most of the so-called bird-tracks of the Trias were certainly made by Dino- saurs, and it is believed that all of them were. This probably belonged to a bi- pedal Dinosaur that lived by the shore of an estuary which deposited the Triassic.
