Atria usually pass through several septa, to as far as XIX. Atria elongate-petiolate, with a narrow, tubular ampulla having thickened muscle layers and a dense prostate covering, and a thinner, ectal duct. Total atrium length 1500–3200 μm; width of ampulla 180–250 μm; width of ectal duct 50–110 μm. Atrial muscle in two layers. The inner (transverse-circular) muscle layer has fibers arranged orthogonally to the longitudinal axis; the fibers appear separate and unordered, in contrast to the lamellar arrangement of the penial musculature; thickness of the transverse layer 7–15 μm in the ectal duct, and 20–50 μm in the ampulla. The outer layer is composed of unordered longitudinal muscle fibers; thickness of longitudinal layer 5–14 μm in the ectal duct, 12–25 μm in the ampulla. Epithelium thin but distinct (2–7 μm) in the ectal duct; very thin and inconspicuous in the ampulla. Longitudinal muscle covered with an even, unicellular layer of peritoneum, and densely packed but separate prostate glands. Prostate glands are pyriform-petiolate bundles, each with many cells, 70– 150 Μm long. Prostate cells granular, with indistinct boundaries; conjoined bundles of ducts penetrate longitudinal muscle of atrial ampulla via longitudinal, lenticular openings; then penetrate circular muscle via transverse openings (
