shell identification help

Hello Edo,

Welcome to the forum. Most of these are not too difficult. A few are "iffy". Species name followed by the family name in parentheses:

1. Cypraecassis rufa (Cassidae)
2. Conus marmoreus (Conidae)
3. Lambis crocata (Strombidae)
4. Tibia fusus (Strombidae)
5. Tonna allium (Tonnidae)
6. At first I thought this was Lunella coronata (Turbinidae). But it's over 2" in width, which would be huge for that species. So I believe it is one of the various forms of Angaria delphinula (Angariidae). A ventral view would be helpful.
7. Distorsio reticulata (Personidae)
8. Architectonica perspectiva (Architectonicidae)
9. Turbo argyrostomus (Turbinidae)
10. This looks like an immature Vasum (Vasidae/Turbinellidae), not sure of the species. Could also be a Thais. A ventral view would be helpful.
11. Lambis lambis (Strombidae)
12. This appears to be a small Vasum ceramicum (Vasidae/Turbinellidae). Not absolutely certain from this view. Again, a straight-on ventral view would be better.
13. Cymbiola vespertilio (Volutidae)
14. Argonauta hians (Argonautidae)
15. Drupa morum (Muricidae)
16. This is a land snail in the genus Amphidromus. Not certain of the exact species. Perhaps one of the many forms of Amphidromus perversus.
17. Strombus canarium (Strombidae)
18. Strombus luhuanus (Strombidae)
19. These are Trochus (Trochidae). The one on the left appears to be Trochus radiatus. The other two may be the same species or other related species. There are a number of small Trochus species that are difficult to distinguish.
20. Vexillum rugosum (Costellariidae)
21. Cypraea caputserpentis (Cypraeidae)
22. Neritina waigiensis (Neritidae)
23. Lambis scorpius (Strombidae)
24. Cymatium lotorium (Ranellidae)
25. Cymbiola nobilis (Volutidae)
26. Terebra maculata (Terebridae)
27. Difficult to see just what this is. Is it a bivalve? If so it is probably Hyotissa hyotis (Ostreiidae). If it's not a bivalve, a better picture is needed.
28. Nautilus pompilius (Nautilidae)
29. Cassis cornuta (Cassidae)
30. Haustellum haustellum (Muricidae)
31. Harpa ventricosa (Harpidae)
32. Strombus bulla (Strombidae)
33. Drupa ricinus (Muricidae)
34. Conus capitaneus (Conidae)
35. Strombus luhuanus (Strombidae)
36. Strombus lentiginosus (Strombidae)
37. Cellana testudinaria (Patellidae) (polished)
