. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. michaelsen: African oligochaeta 435 but I could not recognise them, neither could I recognise a connection between these depressions and the supposed seminal furrows. Equally uncertain is the position of the male pores which are to be sought in the interior of the male field, presumably in the seminal furrows at segment XVIII. Spermathecal pores indistinct, 2 pairs in the intersegmental furrows VII/VIII and VIII /IX in the lines of the median pairs of setae, in ab. Internal Anatomy. Septa VI/VII-IX/X very thin but IX/X slightly thickened in the centre, while X/XI-XIII/XIV are mod- erately Fig. 2. Dichogaster bagiloana. Prostata. Alimentary canal. Two gizzards in segments V and VI. 3 pairs of almost equally large, whitish chylous pouches in segments XV, XVI and XVII, apparently entirely separated from one another, kidney- shaped with relatively smooth surfaces, but their somewhat broad, convex ridge is crossed by many densely-grouped, darker stripes which partly take the shape of furrows. The intestine bears a simple, large, ribbon-shaped, irregularly meandering typhlosolis. Nephridia (mostly destroyed in the type) are very small, sac-shaped, and apparently very numerous (about 6 or more in each half of a segment ?). Anterior male organs holoandric. Two pairs of testicles apparently depend free into the body cavity of segments X and XI; apparently only one pair of seminal vesicles depend from septum 11/12 into seg- ment XII. They are small, much broader than long, multipartite, with a short and narrow stalk. Posterior male organs. Two pairs of nearly equally large prostates (fig. 2) in the body cavity of segments XVII and XIX. These seg- ments are slightly expanded dorsally. Glandular part moderately long, above the intestine, touching or nearly touching that of the other side,.
