while intersegmental furrows become deeper. The genital segments X–XI almost always bear wide, lateral wing-like outgrowths produced by contraction of dorsoventral muscles. These "wings" begin anteriorly in the dorsolateral part of X as narrow strips (Figs 2.1, 2.8), proceed diagonally downwards, and continue in XI as thick lateral folds directed downwards and containing many internal organs; usually they do not reach XII. As a result, the ventral side of segment XI appears deeply concave in fixed specimens (Figs 2.1, 2.9, 2.10). Body dorso-ventrally flattened and thin in X–XI, the thinnest between X and XI where a distinct transversal groove crosses the ventral side (here body often only about

The first part in XI (Fig. 2.7: a1) short but curved or winding, about 20–85 Μm wide, with lumen only 5–6 Μm wide, and consisting of dark-staining glandular cells similar to those of the prostate gland. Prostate gland attached to the first part of atrium and sometimes surrounded by a loop of the latter, slightly lobate, up to 125–250 Μm in diameter. Second part of atrium (Figs 2.7, 2.10: a2) several times longer than body diameter, forming loops in the coelomic cavity of XI–XII; diameter variable (37–110 Μm), wall consisting of vacuolized epithelium, lumen irregularly wide. Third part of atrium (Figs 2.7, 2.9, 2.10: a3) localized vertically in the lateral part ("wing") of XI, 200–400 Μm long and 45–170 Μm wide, with dense wall consisting of narrow epithelial cells; its lumen 10–100 Μm wide, sometimes winding; the external muscle layer about 3 Μm thick. This terminal portion of atrium continuous with a 100–200 Μm long and proximally 65–145 Μm wide conical penis consisting of similar tissue; penis lumen sometimes dilated up to a width of 45 Μm. Penis usually retracted into spacious penial sac but often partially or completely protruded from the male pore. Penial sac 100–175 Μm wide in its proximal portion, with an inner circular fold near the base of the penis (Figs 2.7, 2.10).</paragraph>
