Abstract

IT has been stated that the Müllerian ducts of frogs and toads open into the cloaca comparatively late in life, generally when the female becomes sexually mature1,6. It is not recorded whether they remain open or close up after spawning1–6. In the course of investigations on the urinogenital organs of Salientia, I have observed an occlusion of the oviducal (uterine) aperture in the cloaca which deserves notice.
