Four agamid species, Laudakia caucasia (EICHWALD, 1831), Laudakia stellio (LINNAEUS, 1758), Phrynocephalus horvathi ROSTOMBEKOV, 1938 and Trapelus lessonae (DE FILIPPI, 1865), occurring in Turkey, were hematologically examined [erythrocyte and leukocyte count, total hemoglobin, hematocrit value, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration and total protein values]. In addition, blood smears were prepared from the specimens and erythrocyte length, width, size and leukocyte diameters (lymphocyte, monocyte, eosinophil, heterophil, basophil) were measured and the percentage values of leukocyte types were calculated. The erythrocyte count in L. caucasia was found out to be higher than those of L. stellio and P horvathi. The erythrocyte size in L. stellio was larger than those of L. caucasia, P. horvathi and T. lessonae, respectively. The hemoglobin concentration, hematocrit percentage and mean cell hemoglobin parameters are different among L. caucasia, L. stellio and P. horvathi.
