Well, this species is causing me to go greyer. Who is it? I'm not sure. The overall coloration matches its description in NSSI 2nd Edition except for the subapical band on the cerata which are deep purple not orange.

I tried to find the derivation of the name "macassarana", but Bergh 1905 is written in German, and I am unaware of any reference giving it. Commonly it is called the Orange-tipped Flabellina. However, if we are to use this moniker, we should more accurately call it the Orange-tipped Samla.

I still don't know exactly who it is. Any ideas?
