I can't imagine what these shells are... 1- Negros, Philippines, 26mm: http://www.idscaro.net/sci/01_coll/pics/gastro/neritidae/nerita_sp1.jpg 2- Albuera, Leyte, Philippines, 14mm: http://www.idscaro.net/sci/01_coll/pics/gastro/neritidae/septaria_sp1.jpg Any help will be appreciated. Of course, I studied closely Tom Eichhorst's great work on recent Neritids, but these two shells continue to resist.
