In order to facilitate discussion of the evolutionary relationships of the genus, these new species are described in the present paper. Although several other taxonomic problems exist, the nomenclature of Etheridge (1970) is used herein. A complete taxonomic review will be presented in a paper cun'ently in preparation. It has become apparent that the generic status of all species in the genera Ophnjoessoides Dumeril, 1851, and Stenocercus Dumeril and Bibron, 1837, warrants consideration. My work indicates that many of the species presently included in Ophnjoessoides are more closely related to species of Stenocercus than to other Ophnjoes-soides. All species named in this paper are members of the genus Stenocercus as it is viewed by me. ACKNOWLEDGMENTS I am grateful to Richard E. Etheridge for information on type specimens of Stenocercus and Ophnjoessoides in European muse-ums. He has generously shared specimens in his care and given freely of his time. William E. Duellman has encouraged me in my work with Stenocercus and provided energies in laboratory and field aspects of the study.
