Hello, new member here, looking for help identifying this snail.

It was collected along the banks of Permanente Creek in Mountain View, Santa
Clara County, California (collection site approx. N 37.42299,  W 122.08652),
from among a sizeable population, alongside similar numbers of Otala lactea.
 An aquaintance suggested it is Theba pisana, but according to Roth's
"Checklist of the Land Snails and Slugs of California," T. pisana is not
found anywhere near this part of California.

The snail in question does not share the chocolate brown aperture and
columella of O. lactea, and it had a visible umbilicus when I got it (which
I did not manage to photograph). The shell has grown to cover it up now.
This particular snail mated with an O. lactea in my tank.  The Otala
subsequently laid eggs, resulting in a clutch of 4 dozen baby snails
(hatched on Sept. 17, 2009).

If the snail in question is not some other species of Otala, it is a species
that is capable of breeding with Otala.  Does anyone have any ideas about
its identity?  Thanks in advance.
