, differing in position and morphology, can be recognized. A few (6–10), very large (up to 60 µm long) and nearly straight, are placed radially around the genital area, and in most specimens form a rosette around the genital opening (Figs 2A, B: p1). Others (20 – 30 µm long), more numerous and more irregularly coiled, are distributed mostly in the caudal region (Figs 2A, B: p2), where they are intermingled with rhabdoid glands.

The seminal vesicles are lined by a thin, flat epithelium, and extend laterally and posteriorly from the bulb, into which they enter dorsally. The bulb is 45– 50 µm across, lined externally by a flat, intranucleated epithelium. Below the epithelium, a strong muscular lining, 10–12 µm thick, is present. It consists of relatively few and very large muscle cells, arranged into an external longitudinal and an inner, thicker, circular layer. The bulb is posteriorly oriented, and is connected to the body by a relatively small, ventral area, crossed by muscular fibres which are connected to the body musculature. The bulb contains a cirrus, which originates from the fusion inside the bulb of the distalmost portions of the two seminal vesicles. No prostatic vesicle was observed, nor cell bodies that could be identified as prostatic glands. The cirrus is unarmed, long and very convoluted, so that its length is impossible to measure with any degree of confidence in sections. It is lined internally, at least in parts, by a basal lamina, without overlying epithelium, and it is surrounded by a thin coating of muscular cells, more noticeable distally. The cirrus opens ventrally into the atrium. The rest of the bulb appears filled with somewhat loose parenchymatic cells, with ‘empty’ spaces among cells.</paragraph>

The bursa is lined by an unciliated cuboidal epithelium, and opens anteriorly into the dorsal wall of the atrium through a short, ciliated bursal canal, 10–15 µm long, which receives the female glands. Posteriorly, the bursa is connected to a long (50–60 µm in sections), Sshaped duct, surrounded by very strong circular muscles. The muscle ring closest to the bursa is the strongest, and may act as a sphincter. This duct is lined by an unciliated, nucleated epithelium, and opens into the posterior-most portion of the gut, thus forming a genito-intestinal connection.
