The intrinsic muscles are attached to the seventh bron-chial ring, which is soft and cartilaginous ; where the bronchialrings change their character is a constriction of the mem-brana tympaniformis ; it is, however, of equal breadth beforeand after the change. In Podargus Cuvieri there is a furtherapproach to the purely bronchial syrinx of Steatoniis. The
