THE LEUKOCYTES OF THE ROUGHTAIL GECKO CYTOPODION SCABRUM - A BRIGHT-FIELD AND PHASE-CONTRAST STUDY

The morphology of the peripheral blood leukocytes of the roughtail gec ko, Cyrtopodion scrabum, is carefully described in Wright-Giemsa and t oluidine-blue-stained blood films, and in the living condition by phas e-contrast microscopy, using supravitally stained preparations. Mature eosinophils, basophils and small lymphocytes commonly occur in the bl ood, while monocytes are rarely seen. In addition, macrophages are occ asionally encountered, but neutrophils cannot be observed. Development al stages in eosinophil and basophil differentiation can be seen. This study serves as a basis for the cytochemical localization of substanc es within these blood cells.
