This message is to all, but especially for P.Drez.

I'm studing a lot of Olives from Palawan. They came from
the same locality but I can easily  see that they are
two different types: different protoconch, spire, shoulder
and columella's width. Different also the callous over the
suture-canal. One surely is Oliva oliva but the other
I suppose might be Oliva longispira Bridgman, 1906.

The question is : what is your taxonomic idea about
O.longispira ? Lately it's consider only a form of the
highly variable Oliva oliva...but if I'm able to observe so
many differences, I don't see any intergrade form and
it would be very easy to separate them in two lots ?

The color of the probably longispira is from light cream
background overlaid with longitudinal gray lines and
rare brown spots to dark brown background with
longitudinal black lines and rare yellow spots.
The protocnch is translucent (as ice) within a black
spiral stripe. Very similar to the protoconches of others
O. longispira I own from Vanuatu.

I'm not in a hurry Paul, write me as you can.
Sincerely yours, Maurizio.
