Dear Eduard,
Thank you for your explanation of the differences in the two Cypraea
acicularis shells. I'm sure the shell I have came from Ascension Island as
the person I got it from worked there on the test range and collected shells
there. He identified the shell as Cypraea acicularis sanctaehelenae. I also
have shells I collected from Andros Island Bahamas with the same markings.
The shells I have from off the west coast of Florida do not have the dark
markings. Would I then call the C.acicularis which I collected in the
Bahamas C. acicularis sanctaehelenae?
Thanks again,
Gladys Fehling
