Here is what Rachel Collin had to say- she attached one of her papers
from the Caribbean Journal of Science which described a similar new
species from Panama, and talked about other similar species like C.
navicula from Venezuela (which I so happened to have unearthed two
shells I collected in Venezuela in 2005 and forgot about which appear
to be that species)....I labelled my shell from Eleuthera as "Species,
cf ustulatulina" though I bet it would prove to be different if DNA
testing was done.

I will send you the paper under separate cover offline.
