Abstract. In the present study, the peripheral blood cells (erythrocytes, leucocytes and thrombocytes) morphology of Emys orbicularis and Mauremys rivulata were examined in the blood smears prepared using Wright's stain and the erythrocyte number was conducted as well. In E. orbicularis, the average of erythrocyte length was measured as 20.1µm, width 12.7µm and size 200.8µm2; while in M. rivulata these were measured as 19.3µm, 12.3µm, and 186.7µm2 respectively. The fact that agranulocytes (lymphocytes and monocytes) were dominant cells; nucleus cannot be distinguished in eosinophiles and basophiles due to intensive granulation in cytoplasm; thrombocytes are flat, ellipsoid cells were observed in the blood smears. In 1mm3 blood, the average erythrocyte count in E. orbicularis was 430,666 and 467,500 in M. rivulata, and the erythrocyte count was established to be higher in males.

Key words: Emydidae, Geoemydidae, blood cell morphology, blood smears, erythrocyte count.
