I.—Notes on the Pycnodont Fishes

Abstract
The Pycnodonts were the coral fishes of Mesozoic seas, with a deepened body, produced face, and a small mouth having grasping and grinding teeth, capable of obtaining their hard-shelled food from hollows and crannies. They are evidently not to be regarded as closely allied to any of the typical coral fishes of Tertiary and existing seas, which are spiny-finned teleosteans. They are merely Lepidotus-like and Dapedius-like forms with adaptations to a similar mode of life. The study of their skeleton is therefore of great interest.
