Dear Mark;-
     Since all these cedonulli type "species" occur in the Caribbean,
and differences seem to depend on which isle one is collecting from,
would this not be the perfect place to use the designation "sub-
species"? If you don't like that, how about "form"?
     One is reminded of the slight difference in land tortoises found
on different islands of the Galapagos. The differences allow the
island of origen to be pin-pointed but the tortoises are clearly
closely related and probably in the same "species".
