In all these lacertians the process is developedfrom the articular element, not from that called angulaire byCuvier. The coronoid process is formed by the coronoid element, 31, inMosasaurus as in Monitor and Iguana; in the Python it is anexogenous lamelliform process of the surangular plate of theangulo-surangular element; to the antero-internal part of thiselement the coronoid (fig. 21, c) is applied, slightly projecting infront of the coronoid process, and chiefly disposed, like the sple-nial, to cover the groove at the postero-internal part of thedentary element.
