Etymology

The genus name is a compound of creno meaning "spring", a reference to the desert springs this species occurs in, and ichthys which is Greek for "fish". The specific name honours the American ethnologist and naturalist Vernon Orlando Bailey, who co-collected the type along with C. Hart Merriam.
