The carnivorous Dinosauria form a well-marked order, which the writer has called the Theropoda, in his classification of this group. Although much has been written about these reptiles since Buckland described Megalosaurus in 1824, but little has really been made out in regard to the structure of the skull, and many portions of the skeleton still remain to be determined.
