Marionia olivacea from the Japan Sea

From: Shigeru Hayashi

Dear Bill,
Here are some photos of Marionia olivacea which was promised before.
It was collected from a fishing net with 30 - 50 meter depth. Those individuals were provided by The Notojima Aquarium.

Data: Toyama Bay, The Japan Sea, 30-50m, July, 13-24. 2002

I think M. olivacea resembles the Atlantic species M. blainvillea.

Yours Sincerely,

Dear Shigeru,
Thanks for this addition to the Forum. In both of Baba's description he notes the colour as being 'generally olive in colour' so these photos give us a much better idea of this species' colours. Your photos fit one of the illustrations in Baba, 1949 (Pl.34, fig. 126) very well.
Best wishes,
Bill Rudman
