a set of nerites to id

[diocrisseashells1000]

Thanks Paul for your great info, it gives me clue on where to search the names.

1-3 i think it is more like neritina pulligera because of the dark stain in the parietal wall,

4-6 i dont know, perhaps you are correct to say it's Neripteron siquijorensis, the coloration is just different to my shell.

7-9 yes! it is neripteron violaceus. thanks for the id.

10- 11 i guess it is more like Clithon subrugata. ( Recluz, 1842 )

12-13  it is more look like Clithon subpunctatus  ( Recluz,  1843 )
