 * 1882, Journal of the Royal Microscopical Society, William & Norgate; series II, Volume II, page #181:
 * In the primitive mass of mesodermic cells destined to form the sexual organs an excentric cavity appears, becoming the sexual vesicle ; this divides into an exterior, female, and an interior, male portion ; both are hollow and open into a long common tube formed of flat cells, which lies between the intestine and the gastro‐œsophageal part of the alimentary canal, ending blindly at each extremity.

 * The gastro‐œsophageal ganglia which are described as occurring on the anterior border of the buccal ganglia in typical Dorididae, are apparently completely fused with the buccal, which are regularly ovoid in shape and show no protuberances or other trace of the gastro‐œsophageal ganglia, excepting the single nerve.
