They are composed of several short lobules almost fixed to the ventral wall; they could be the equivalent of prostatic glands found in other crassiclitellate worms. We were unable to see any intraparietal connection with male gonoduct. They are superficially like the septal glands present in the anterior segments. No tubular, atrium-like glands were present.
