Clitellum XIV—XVf, without setœ. Spermathecal pores two pairs, in VI/VII, VII/VIII ; no genital papillœ near them. Male pores in XVIII, of the shape of transverse slits, close to the lateral mar- gin of the body ; no genital papilla? near them (fig. 13). First dorsal pore in XII/XIII. XVIII J TYae A Fig. 13. Gizzard in Vili, IX ; intestine beginning in XVI, with one pair of cœca with 4 pairs of secondary diverticula in XXVI ; of these diverticula the dorsal ones are longest and reach segment XXIII. Septa all thin, none of them being especially thickened ; septa VIII/IX, IX/X wanting Sperraathecœ two pairs, in VII, VIII, with spherical sacs and short ducts ; diverticula shorter than the main portion but convoluted (fig. 14). Sperm reservoir in XI, XII, lobed. Ovary and ovisac comparatively large» Prostate gland somewhat rectangular, in XVII—XIX. Sperm duct with a'terminal sac (fig. 15). Externally this species closely resembles P. sexla Benham, but differs from it in the position of the first dorsal pore, in the number of setœ betweei the male pores, and several internal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Nihon Do?butsu Gakkai; To?kyo?
