The aim of the investigation was the systematization of the bony elements in the orbito-nasal septum and the verification of the notion "mesoethmoideum" in birds. The macerated skulls of adult ostrichs, chickens and pheasants were examined by use of the optic- and radiophotography. In ostrichs were the characteristic interorbital septum as the alar bone integrated with the elements of the prefrontal bones. In chickens were two biochemical systems: a) the anterior alar lamina and b) posterior part without bony trabecular diploe elements. In all birds the author did not found any "mesosthmoideum". These presented facts led to further study in birds, fishes, mammals and man.
