These snails are native to the rivers of the northwestern United States and adjacent British Columbia. Several species are endemic to isolated large springs in the American Great Basin.
The most abundant and widespread species, Juga plicifera, attains a height of up to 35 mm. It is sculpted with fine spiral ridges and variably developed ribs that frequently disappear in parts of the shell made as the animal matures.
The following species and subspecies are recognized:
