substance of the foot, but does not form a caudal mucous pit. The reproductive system anatomically differs from genera Powelliphanta and Wainuia. There is remarkable extreme reduction of male organs in Paryphanta busbyi and the absence of receptaculum seminis (spermatheca). This is resemblance with Schizoglossa novoseelandica. There is a blunt, somewhat triangular, projection of the vaginal wall, with a retractor muscle proceeding to the adjoining body-wall; this is the only evidence of the male organs before any of the surrounding tissue has been dissected away. On removing this outer tissue a small loop is seen to project from the vaginal wall. This is the posterior termination of the penis, which passes into the vas deferens without any perceptible change, except a slight diminution of the tube. The anterior portion of the vagina forms a wide chamber, closed posteriorly by a valve-like papillar structure; the interior walls are slightly darkish in colour, and weakly longitudinally plicated. The papilla is continuously united with the vaginal wall, and the perforation through its centre is the only communication with the oviduct. Its anterior third projects freely into the anterior vaginal chamber. Its walls are comparatively thick; internally they are lightly longitudinally plicated, and have a whitish epitheloid lining. The penis opens into the posterior portion of the papillar structure in the form of a small tube; it proceeds through the thick vaginal wall in an oblique anterior direction, and becomes slightly enlarged or bulbous towards its termination. The vas deferens, as previously stated, is free to a very limited extent, and is imbedded in the vaginal wall. Its posterior prostatic course through the prominent folds or plications of the oviduct is tubular, thence open, but for a short distance enfolded on all sides by the above-mentioned plications. From this point to the albumen gland it is a well-marked area of a rusty brownish tint, and somewhat separated from the uteral portion by the longitudinal folds. The uterus is thrown into numerous sacculations, and its interior walls are richly convolutely plicated. There is no indication of a receptaculum seminis. The albumen gland is very large, a usual feature in this group of animals; in outline it is roughly boot-shaped. The hermaphrodite duct enters near the base of the albumen gland; it is a simple straight tube, with several short lesser tubes branching from it and uniting with the several masses which form the hermaphrodite gland.
