The name is from the Latin patera ("a saucer"), and refers to the highly depressed, saucer-like shape of the shells of these snails. In addition to flattened shells, members of the group have an imperforate umbilicus and a single tooth on the parietal wall of the aperture.[2]

These snails are known only from the eastern United States.[3]

gollark: Unfortunately, I have no more detailed per-process logs and thus absolutely no idea what was using that much CPU.
gollark: No apparent correlation to RAM use.
gollark: And as such power draw was at 95W for this duration.
gollark: It is pretty great though; for instance, I can see that from 07:28 to 18:44 CPU usage was at slightly over 14% on all cores for no apparent reason.
gollark: I wonder if I can make it downsample older stuff.
