Dear Bill,
Concerning Mike Greenemeier's message #13508:

I believe this is Diaulula greeleyi (MacFarland, 1909). I have attached photos and text are from Zeiller (1974), as Peltodoris greeleyi, who incorrectly named Marcus & Marcus as authors. The left-hand photo is correctly identified, but the two animals in the right-hand photo, referred to here as a color form, are in fact examples of Diaulula farmersi Valdes, 2004.

  • Marcus, Er. (1955) Opisthobranchia from Brazil. Boletins da Faculdade de Filosofia, Ciencias e Letras da Universidade de Sao Paulo, Zoologia 20: 89-262.
  • Marcus,Ev. & Er. Marcus. (1967) American Opisthobranch Mollusks. Studies in Tropical Oceanography 6. 256 pp.
  • Valdes, A. (2004) Tropical western Atlantic species of Diaulula Bergh, 1878 (Mollusca, Nudibranchia), with the description of a new species. Contributions in Science, 501: 1-7.
  • Zeiller, W. (1974) Tropical Marine Invertebrates of Southern Florida and the Bahama Islands. John Wiley & Sons: New York. 132 pp.

Dear Colin,
Thanks for the scan of Zeiller's page. Unfortunately for copyright reasons I can't copy it withour permission, but certainly the left hand animal is the same. I had looked at Marcus' descriptions of this species and hadn't been able to clearly identify it as this species but I am happy to accept the views of local workers. I must say the high rhinophore sheaths are very distinctive.
Best wishes,
Bill Rudman
