After some practice, we were able to pick out the Fly-specked Ceriths from the Dark (Florida) Ceriths. These were from Lighthouse Beach.

Here's another set of cerith-like snails of which I'm not sure of the identity. They might be ceriths, false ceriths, or--since they came from the Causeway Islands--some recent fossil of yet something else. I also have a hunch that the upper two are different from the lower two, in which case I can split this observation if needed.

These are three very worn shells of the dark cerith. The shell at the back has an intact aperture, whereas the one in the front is is quite broken. This shell is perhaps a little uncommon in the beach drift on some of the beaches of Sanibel, but quite common on some other beaches. These three shells were the only ones of this species that I found in the first three days of collecting on the beach at West Gulf Drive, the first time I ever visited Sanibel.

These were by no means common but it was the one regular small gastropod we were finding among the masses of bivalves in tidal drift on the beaches. They were a bit more numerous at Lighthouse Beach Park than elsewhere. I have a sneaking suspicion that the left-most snail (closest to the rule) may be something different, based on the shape of the aperture, but I'll need some coaching on that.

These examples were picked up on the Causeway Islands.

I'm not sure if this is a cerith (Cerithium) or false cerith (Batillaria minima). I think it's too big to be the latter.

Found in dried mudflat in lagoon marsh. Photographed in hotel later.
