ID of shells found on east coast of UAE / Oman

[dave r]

Hi Em, I will try my best but as I said before, you really need to show both top and bottom views to identify a lot of shells.
#9 looks to be , top to bottom; Cypraea arabica, Arabian Cowry; C. grayana, Gray's Cowry; C. histrio, Actor Cowry
#10 C.pantherina, Panther Cowry
#11 C.turdus, Thrush Cowry
#12 Trochidae species, possibly Trochus radiata but need to see the aperture.
#13 Architectonica perspectiva, Perspective Sundial
#14 C. leviathan titan or C. carneola, again need to see aperture.
Cheers,
Dave
