Dear Bill,

I am pretty sure that Placida is the correct genus for Placida cremoniana. It has a penial stylet and blade-shaped radular teeth according to Schmekel & Portmann (1982). I have never seen the beast alive. Also, I am not sure that what has been called Placida (or Hermaea) cremoniana outside the Mediterranean (e.g. Japan and Australia) is actually the same species. We need more detailed studies of reproductive systems.

Greetings,
Kathe

Thanks Kathe,
I checked Trinchese who also describes blade-shaped teeth. I must say that until I saw Thierry's photo of a Mediterranean specimen I had my doubts about the identity of specimens from the Pacific. I agree that we need to look at the anatomy of these animals. However the colour and shape seem to be identical.
Best wishes,
Bill Rudman
