The skull which has furnisht all that we know of this species is a most extraordinary one. It was found in the lower bed of greensand, belonging to the upper Cretaceous, near Barnes- boro, Gloucester County, New Jersey, and is now in the geological collection of Rutger's College, New Brunswick, New Jersey, where the writer has been permitted to examine it. It was fully described and figured by Leidy in his original description. His figures are stated to be of the size of nature, but they are really somewhat reduced. Plate 23, figs. 2, 3, of the present work is reproduced from drawings belonging to the U. S. Geological Survey. These were prepared in 1888 for Dr. George Baur, who was then preparing to monograph the fossil turtles. The one showing the lower surface of the skull differs from that of Dr. Leidy in indicating the positions of the sutures. It will be observed that in this drawing the missing quadrate regions are restored in outline. The skull, from the tip of the snout to the occipital condyle, had originally a length of close to 70 mm. The width at the hinder end of the maxillae is 70 mm. From the latter point.
