Abstract

Abstract T he Kimmeridge Clay of Shotover Hill has yielded five specimens of the teeth of this reptile, now for the first time represented as a British genus. After noticing the bibliography of the subject, and the presence of specimens in various museums, the author proceeds to describe the characters of the teeth. They are large, conical, incurved, and slightly recurved, having two sharp, prominent, crenulated, longitudinal ridges, which are situated midway between the convex and concave curvatures. This reptile is regarded by the author as foreshadowing the form of dentition that characterizes the existing group of Varanidœ . If the materials were at hand for a complete definition of its comparative osteology, Dakosaurus would probably exhibit a combination of Lacertilian and Crocodilian characters, but with the crocodilian elements predominant.
