Forms?  I get the impression they are different species.  I took a
closer look at them and there are other differences as well.  The siphon
of the darker tun with defined spiral sculpture is straighter and it has
a white mouth.  The Caribbean shell will at least have a light brown
mouth.  Of course, I have a very limited amount of tuns to study.

I guess it really depends on whether you are a lumper or a splitter.  I
tend to be on the splitting side.  Many synominized shells have
consistent differences.
