Abstract
ART. XLII.-T/zeOranial Musculature and tile Origin of 25726 Frill in tile C'eratopsian Dinosaurs ,' by RICHARD S. LULL.(\Vith Plates 1 to III.) DOLLo (1884) in his fifth note on the Dinosaurians of Bernissart has discussed the muscles of mastication of certain dinosaurs in comparison with those of a rodent, a crocodile, and achameleon.This work has suggested to the writer a further study of the musculature of the skull, especially in the Ceratopsia, With a View of gaining an insight, if possible, into the origin of the peculiar defensive cranial armor of this remarkable group.These studies are based more particularly on the type skulls of Triceratops serratus and T. 12700748248 Marsh Which are preserved in the Peabody Museum at Yale, supplemented by an admirable palate, referred to the former species, in the American Museum of N atural History.The chief basis for comparative study has been the modern chameleon, Which, as the author Will show, exhibits some very remarkable points of convergence in structure toward the Ceratopsia.'PART I.
