Crenichthys baileyi (Gilbert, 1893)

The White River springfish Crenichthys baileyi, is a rare goodeid fish of the Great Basin of western North America, native to various warm springs in the White River drainage of eastern Nevada.

Each side has two rows of dark blotches. The pelvic fins are entirely absent, while the anal fin is large, with 14 rays. The dorsal fin is set far back on the body, just above the anal fin, and is somewhat smaller than the anal fin, with 11 rays.

Several subspecies have been identified, each associated with a particular location. Authorities differ on the numbers, but FishBase records five:

• Crenichthys baileyi albivallis
• Crenichthys baileyi baileyi: native to Ash Springs
• Crenichthys baileyi grandis: native to Hiko Spring and Crystal Spring (endangered)
• Crenichthys baileyi moapae
• Crenichthys baileyi thermophilus

This species was named in honor of naturalist Vernon L. Bailey.
