VOL. XVII, PP. 17-20 FEBRUARY 5, I9C4 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW LIZARD FROM THE RIO GRANDE VALLEY, TEXAS. BY LEONHARD STEJNEGER. {By permission of the Secretary of the Smithsonian Institution.] During the various collecting trips made by the field natur alists of the Biological Survey into western Texas, a series of lizards belonging to the genus Sceloporus were collected, which clearly belong to an undescribed species. It forms part of the small section of the genus characterized by the minuteness of the lateral scales, of which, thus far, only two species have been taken within the United States, viz., S. variabili-s and S. couchii. I wish to associate with this very distinct species the name of the originator and chief of the Biological Survey, who has done such an immense work in increasing our knowledge of our vertebrate fauna, Sceloporus merriami sp. nov. Diagnosis. Lateral scales minute, granular; 55 to 56 femoral pores in a continuous series across the preanal region; 56 to 66 scales between the shielded part of the head and the base of the tail; 14 to 18 dorsal scales corresponding to the shielded part of the head; head shields smooth. Habitat. Rio Grande Valley, western Texas. Type. United States National Museum, No. 33,039; East Painted Cave, 2 PBOC. BIOL. Soc. WASH, VOL. XVII, 1904. (17)
