Olives: two doubtful specimens

[cebrizi2]

Thank You Dave for your determination,

I do not oppose your very welcome and well-placed determinations, I would only like to let you know why I didn't propose them in first place.

The supposed O. caroliniana is not easy to tell. I have another specimen that was assigned to O. caroliniana by Mr. Monfils, if I remember correctly, that is somehow different. I'll check where and let you know.

About O. caerulea, many things coincide (and the internal color is in fact very blue), but (apart being much smaller that my other caerulea specimens) the columellar folds do not resemble those in the other O. Careulea that I have. The problem is that I took for granted some determinations made by the people selling me the shells, when in fact they too are doubtful (e.g. my "original" caerulea may not be a caerulea after all...).

Add those uncertainities to the intrinsic difficulties with many Olives, and without the very limited bibliography I have at hand...

Many thanks, for now I'll stick to your suggestions.
