Thorunna australis? from Philippines

June 19, 2000
From: Erwin Koehler

Dear Bill,
This one is from the Philippines, Cebu Is., divesite "Canyon reef",
March 2000, depth 15 m, size approx.2 cm.
The photo is by Hans-Hermann Harms. I think it looks like Thorunna australis.

Dear Erwin,
Much of the colour seems to have been washed out of the photo, but from what I can see, including the red bands on the rhinophores and gills, I agree that it is probably Thorunna australis.
Best wishes,
Bill Rudman.
