Dear Bill,
Concerning the Tambja from Ecuador message. Since this message is from my side of the Pacific, I would like to comment.

This picture I am sending is the typical Tambja eliora as described by Marcus & Marcus.

Since I first saw PeterĀ“s picture I have wondered if it is in fact the same species. Marta Pola (Calif. Academy of Sci) is working on a worldwide revision of Tambja, Nembrotha and Roboastra. It would be very interesting to know what she has to say about this if she ever comes about one specimen to dissect. (If anyone out there would be so nice to send her some!)
Cheers
Ali

Dear Ali,
I rely on comments from 'local experts' especially in regions such as the eastern Pacific, where there is so little published work. It's possible that the spotted animal is a separate species, but the only difference is that the blue lines have broken into a string of blue spots. It would certainly be interesting to confirm the suggestion that the colour pattern changes from lines to spots the further south you go down the east Pacific coast. Hopefully if Marta contacts Peter or Soledad, some specimens could be obtained. However I think that when you have very similarly coloured 'forms' like this, living in close geographical proximity, it is vital to study the variability of the whole population before deciding how many species there are.

I would appreciate some locality data for this photo.
Best wishes,
Bill Rudman
