From: Sylvain Le Bris
Dear Bill,
I couldn't succeed to identify this Facelina. Is it F. bostoniensis or F. albida or F. auriculata? or another species !
Locality: Marseille, 15 m, France, Mediterranean sea, 28 June 2008. Length: 2.5 cm. Photographer: Sylvain Le Bris.
Thanks for your help
Kind regards
Sylvain

This is Facelina auriculata. It has similarities to F. bostonensis but in F. auriculata the cerata are shorter, and in distinctly separate clusters. Also, the cerata usually don't extend beyond the posterior tip of the foot. Another character is that F. auriculata always has the blue streaks on the cerata which are absent in F. bostonensis.
I am not sure what you mean by F. albida?
Best wishes,
Bill Rudman
