About Favorinus mirabilis

December 3, 1999
From: Francisco J. García

Dear Sir

I would like to know if the species Favorinus mirabilis is described with the rhinophores perfoliated (Baba 1955; Willan, 1983) or if have been found specimens with other type of ornamentation. In this way, could you send me references where these aspects or other anatomic features of F. mirabilis have been published?

Thanks in advance
Francisco J. García

Dear Francisco,
The only reference I know to this species is Baba's original description in the 1955 supplement to Opisthobranchia of Sagami Bay. I am not sure of your reference to Willan 1983.

Baba describes the rhinophores as being 'distinctly perfoliate' and shows it in both the coloured painting and the black & white drawings. The rhinophores are very dark brown. He describes the general body as 'whitish' and cerata as being 'brownish'. The distinctive colour features would appear to be a purple spot near the tip of each ceras and yellow oral tentacles and a yellow margin to the foot.

If anyone has a photo of this animal, or further information, it would be welcome.
Best wishes,
Bill Rudman.
