Remarks : There was uncertainty concerning the age of the localities in Cavender and Miller (1972:3-4). They 
listed the sites as either Barstovian or Hemphillian before the publication of the revised assignment of ages 
at the Miocene-Pliocene boundary [Beiggren and Van Couvering (1974)]. According to Woodbume and 
Swisher (1995), Barstovian is now considered Middle Miocene and Hemphillian is considered Late 
Miocene. Eiting and Smith (2007) considered the type locality to be Middle Miocene.

Type Specimen : f Rhabdofario lacustris Cope 1870, holotype, USNM 16352 (Cope listed it as 9790 
Smithsonian Collections), partial cranium and jaws. 
Type Locality : Castle Creek, Owyhee County, Idaho, Glenns Ferry Formation, Early Pliocene, non-marine. 
Referred Specimens in Cope (1870) : From Catherine Creek, Glenns Ferry Formation?, Early Pliocene, 
Owyhee County?, Idaho, non-marine: Smithsonian Collections 9785-9786. 
They synonymized die genus 
Rhabdofario with Salmo and applied the new specific name because the name lacustris was preoccupied 
in Salmo. Cavender and Miller (1972) returned to the original name because the two genera are distinct. 
(Smith 1975:7). No mention of specimens of 1*7?. lacustris from California. 
( 1972 ): See above entry. No mention of specimens of f/?. lacus¬ 
tris from California.
