Hypselodoris agassizii & Chr. sphoni

Dear Bill,
It was good to see the photo of Hypselodoris agassizii. Angel Valdes and I were in Costa Rica in January working with our colleague Yolanda Camacho at the National Institute of Biodiversity on the molluscan inventory project. We were able to collect material from localities along the southern Pacific coast. We saw many examples of H. agassizii. It is the only Hypselodoris that has interrupted marginal lines. What is interesting is that it has a similar color pattern to Chromodoris sphoni that is also commonly encountered in this part of the tropical eastern Pacific. I am enclosing another image of H. agassizi [UPPER] and one of C. sphoni [LOWER] for comparison.

Gosliner, T., 2000 (Feb 25) Hypselodoris agassizii & Chr. sphoni. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1961Thanks Terry,
Glad to hear your new job still allows you time out to do some malacology. I must say I had never seriously looked at this east Pacific group of similarly coloured chromodorids until I tried to identify Erwin Koehler's photo. Its remarkable how these two have both broken the marginal colour bands at the same place, and both have whitish gills with blackish tips. Doesn't Mexichromis tura also have a very similar pattern?
All the best,
Bill Rudman.
