Here are a couple of elderly Cyerce shots. Both were doctored up quite a few years ago for use as Xmas cards. We have a number of polybranchs but have not done much with the limited literature we have on the beasts.

[Bergh named this species Cyerce nigra var. ocellata Bergh, 1873; Samoa]
LOWER: Cyerce nigra Bergh, 1871, 15mm. Chuuk, Ueno, reef flat; 2 July 1973. Host: ?

Thanks very much for the photos. They may be old but they are better than mine. I've decide to keep Cyerce nigricans and Cyerce nigra separate. I am not sure they are distinct, but the colour differences are quite large, and keeping them separate may stimulate discussion.
