Show ANATOMY OF THE LEATHERY TURTLE. 3 2 3 R e produ ct ive O rgans . The ovaries are attached by the parovarium to the dorsal peritoneum just lateral to the efferent renal veins. They are very similar to those of Chelone, and, in this young individual, have the form of a flattened band very much folded transversely upon itself. They extend from about 3 cm. behind the posterior end of the kidneys to nearly the same distance in front of their anterior end. The oviducts, like the ovaries, are in a very immature condition. Each extends from the uro-genital sinus to a point some little distance in front of the ovary, suspended from the dorsal body-wall by a peritoneal fold that passes on anteriorly for some distance beyond the mouth of the duct. The duct does not occupy the free border of the peritoneal fold, but lies about 1 cm. within i t ; the mouth, however, opens actually upon the free border. The anterior part of the oviduct is slightly wavy. Posteriorly the oviducts enter the lateral walls of the urogenital sinus, near the ureters; but on neither side do they in any way communicate with the cavity of the sinus. After an injection of water into both oviducts had failed to show any such opening, the oviducts and ureters were slit up (text-fig. 73). Upon Text-fig. 73. lifp Dermochelys coriacea, part of wall of uro-genital sinus, with termination of oviduct and ureter (right side). entering the wall of the uro-genital sinus, the character of the lining of the oviduct suddenly altered, from being perfectly smooth it became deeply laminate longitudinally. This pleated segment of the duct passed towards the urinary papilla and gradually narrowed to a blind end. Fluid injected down the right ureter entered the uro-genital sinus by two mouths situated on the apex of the urinary papilla. When the ureter was opened it was found that close to the apex of the papilla it forked, each branch being in connection with one of the two openings. On the urinary papilla of the left bide there were also two |
