Hi Em, you have given me a lot to identify and a lot of problems as some are just too worn to name, but here goes.
#14 Cypraea carneola juvenile
#15 Chicoreus virgineus
#16 Polynices sp. Poss. tumidus
#17 Fusinus sp. Poss. arabicus
#18 Murex forskoehlii
#19 ? Gibbula sp. Too worn to i.d.
#20 Cypraea grayana
#21 Turbo coronatus
#22 Nassarius distortus
#23 Cypraea erosa
#24 Semicassis sp. Poss bisulcata? Too worn to i.d.
#25 Pinctada sp. too worn again. This is one of the true pearl oysters.
#26 Natica sp. poss. vitellus too worn.
#27 Cypraea grayana
#28 No idea
#29 Nassarius sp. poss. distorta but far too worn to i.d.
#30 Poss. Gyrineum sp., again too worn.
#31 Cypraea grayana
#32 Cypraea turdus
#33 Cypraea erosa (very worn)
#34 Conus sp. poss. dictator
#35 Duplicaria duplicata
I have done my level best but as I said, some are far too worn to identify. If anyone else fancies helping feel free to chip in!
