Summary:The study deals with the histoenzymological mapping of acid phosphatase and 5-nucleotidase in the various nuclei of diencephalon and mesencephalon of Uromastix hardwickii. Almost all the nuclei and the fiber tracts reveal positive activity, both for acid phosphatase and 5-nucleotidase, althouh the intensity of the enzymatic activity presents great variations. Acid phosphatase preparations have generally revealed moderate or mild activity. On the contrary, the 5-nucleotidase preparations demonstrate the activity of a higher order. For this enzyme beside the nuclei, the commissures and fore-brain bundles are seen equipped with very intense activity. On the other hand, the commissures and fore-brain pundles present moderate activity for acid phosphatase. An attempt has been made to discuss the significance of the distribution of the enzymes at various locales.
