Females brood young within the genital tract. Species usually live in springs. The genus is differentiated from others by the structure of the male and female reproductive systems.[4] Most of these snails occur in western North America, especially the Chihuahuan Desert. There are also species known in Florida and Guatemala.[4] SpeciesSpecies include:[5]
