#1  Nerita exuvia  L., 1758, a more beachworn specimen than the one you posted in your previous group.
#2 Â Nerita albicilla
The rest all look like Donax species, which are very difficult to identify except for a few unusual species. Â Also, there are some small bivalves from other families that resemble Donax, so I can't guarantee that they are Donax.
Hi. I send 5 new pictures about seashells from Borneo. In this case the pictures are from Bako. inthe East coast. Can you help me to ID?.
Thanks. Rafa.
