Ed and Barbara Haviland,
As a non-olive specialist I planned to stay out of this -- but I did a quick
check and of my 60+ species and subspecies of olive I have exactly NONE of
the ones you listed as rare. The closest I get is O. rubrolabiata but mine
is the normal colored form (I didn't even know there was a light colored
form). I also checked two shell books and didn't find these guys listed.
Thus I believe we have to accept your list.
And this is from a sampling of a collection numbering 1/100th of your
collection!
