Resumen
An osteological description of the syncranium and hyoid apparatus of Ameiva ameiva (Linnaeus, 1758) is presented. By comparison between males and females signiflcant intersexual differences were found in relation to: skull size, frontal, parietal and basisphenoid bones, interpterygoid opening and teeth number and mor-phology. Absence of pterygoid teeth in A. ameiva is verified out. The specimens used for this study carne from Chaco and Formosa provinces (Argentina).
