Peringia ulvae is 10mm by 5mm

whereas Assiminea grayana is more rotund at 5mm by 3mm. What do you think?

Which snail

Yes. by shape it does look more like Assiminea grayana. I'd forgotten this was a possibility on east coast saltmarshes and assumed it was the more widespread Hydrobia/Perinia ulvae. On size though, they're pretty similar. H. ulvae is more like 5mm x 3mm, max 6mm length according to this site:http://species-identification.org/species.php?species_group=mollusca&id=734
