A photo of 'typical' Ancula pacifica

June 11, 2000
From: Dave Behrens

Dear Bill:

You have been looking for a photo of the more typical "yellow lined" color of Ancula pacifica MacFarland, 1905 to add the Forum.  I have finally tracked down this fantastic photo taken by Bruce Wight at San Clemente Island, California, in October 1996.

Bruce's photo represents what most of us believe is a typical A. pacifica, based upon its original description from this coast.  This species differs dramatically in its external features from the recently collected individuals in the Vancouver, B.C. area, posted on the Forum, as A. gibbosa.

We now have specimens and a close internal look will answer the identify question.

Dear Dave,
Thanks for the photos. Marli Wakeling said she was sending you some specimens of the colourless form. Good to see the Forum helping to solve another little problem. I suppose it is possible that the European A. gibbosa, the white-spotted animal, and A. pacifica are all distinct species. It will be interesting to see what you find.

To remain unbiased on the question I'll temporarily leave Ancula pacifica and the colourless form together on the A. gibbosa page, but I'll put both names in the Species List.

Best wishes,
Bill Rudman.
