Note added 11 March 2010: This is now considered a species of Dermatobranchus. [See message #23319]

Dear Bill
This specimen is Armina sp. I found it in 50-60 feet at Chomporn, Thailand . Its size is 3.5 cm. So could you please identify it for me.
Thank you

Dear Narongpon,
There are many species of Armina and Dermatobranchus which are in need of investigation. This animal looks very like the species Baba (1949) identified as Armina japonica (Eliot, 1913). Debelius identifies another species from Sydney Harbour as Armina japonica and states that the papillae on the oral veil are characteristic which is in direct contradiction to Baba's "head veil smooth above". Eliot's original description also mentions a smooth oral veil so I don't think Debelius is correct.

Are you sure it is an Armina and not Dermatobranchus?
Best wishes,
Bill Rudman.
