Hello again,
This time I am in trouble with Madagascar bivalves. They have been recently collected from the Mozambique Channel (West coast near Morondava, an estuarine area). I hope you could help with a few of them if not all.

B: Looks more like a member of Mesodesmatidae as of Donacidae, but I'm not sure in this

C: Donax madagascariensis (Wood, 1828)  <span class="petit">--Last edited by mikede on 2008-06-27 00:07:54 --</span>
