In the male Platana note:—
(a) The testes, a pair of ovoid pale-yellow bodies attached to the dorsal wall of the body cavity by a fold of the peritoneum. They lie on the ventral sides of the kidneys and are connected to them by efferent vessels which pass into the kidneys.
(b) The corpora adiposa or fatty bodies lying in front of the kidneys.
(c) The ureters which run along the outside of the kidneys and unite posteriorly to form a single duct opening into the cloaca.
[In the Frog the ureters do not join together but open separately into the cloaca. Each ureter has a slight swelling, the vesicula seminalis, on its outer side.]
