There were two pairs of testes. Sperm ducts (his Plate II, Fig 15) are shown joining anterior to the penis to form a single seminal vesicle full of mature sperm, which opens into the base of the penis via a single opening. A blind sac (“glande accessoire”; his Plate II, Figs 12 & 15) opens near the junction of the ovovitelline ducts, but the description of the female ducts in this region is vague. There was no genito-intestinal connection.</paragraph>

shows a “vesicula seminalis” at the base of the penis. It lacks stored sperm and unfortunately the diagram does not show the entry of the sperm ducts. The text states that “On my animals (sperm ducts) were not raised to false seminal vesicles”. He continues: “The well-formed, elongated cone-shaped penis protrudes from above into the atrium masculinium. The muscular penile bulb surrounds the elongated eggshaped seminal vesicle, which gradually narrows downwards and passes into the ejaculatory duct.” Thus, what he calls the seminal vesicle is inside the muscular bulb of the penis and appears to be the proximal, wider, part of the ejaculatory duct within the penis. The lack of stored sperm in any part of the male system could be because the specimens were either not fully mature or possibly spent. A genito-intestinal duct was present opening near the junction of the ovovitelline ducts and their opening into the common female duct. The opening of this duct into the intestine is shown (his
