The openings of the glands associated with the spermathecal and male poresj are very difficult to re- cognize from the outside, owing to developed, lobate, in XVII—XX. 26. P. levis, n. sp. Length 85 mm., breadth mm. ; number of segments 88. In alcoholic specimens dark brown on the dorsal side, whitish on the ventral side. Number of setœ in the spermathecal region 45, posterior to the clitellum 48. Clitellum pale yellowish, XIV—XVI, without sefce Spermathecal pores two pairs, in VI/VII, VII/VIII, surrounded by small papillae, the openings of glands, which, however, are often absent. Male pores difficult to recognize with the naked eye. No genital papillae either near the spermathecal or male pares. First dorsal pore in XIl/XIII. Gizzard in Vili, IX ; intestine beginning in XV, with 5 pairs of cœea decreasing in length towards the ventrum in XXVII, the longest of which reach segment XXV. Thickened septa V/VI—VI/VII and X/XI—XII/X1II ; septa VIII/IX, IX/X wanting. Spermathecœ two pairs, in VII, VIII ; main \ sac pyriform ; diverticulum consisting, like the main sac, of a thin-walled sac-like portion and a thick-walled duct. Two whitish " capsulogenaus glands " close to each sperma- thecal opening, similar in shape to those of P. Hilgendorfi Mich. (fig. 12). Sperm reservoir in XI, XII. Ovary and ovisac very large, lying close to the ventral wall. No prostate gland. Male ducts terminating, as in the allied species, with a knob-like swelling more frequently in a segment anterior or posterior to XVIII and only very rarely in the Please note that these images are extracted from scann
