Yasuhiro's Favorinus mirabilis

April 30, 2005
From: Atsushi Ono

Dear Bill,
Concerning Yasuhiro Shirai's photograph [message #2108]. This aeolid has the possibility that it is Favorinus perfoliatus Baba, 1949. The shape of rhinophores are peculiar apparently unique among the species of  Favorinus described from Japan. It is possible the type specimen might help - the figure in Baba, 1949 is not very clear.
Sincerely,
Atsushi Ono

Dear Atsushi,
I agree that Baba's description of this species is not very useful. Certainly the 'perfoliate' rhinophores are unusual in the genus, and apparently different from those of F. mirabilis and F. tsuruganus. I am happy to follow your suggestion that we tentatively identify this animal as Baba's F. perfoliatus. One obvious need is to check the anatomy of a known specimen.
Best wishes,
Bill Rudman
