Vol. XIV March-April, 1937 Nos. 3-4

by Ranger Naturalist James R. Simon

Many scientific names of Yellowstone Park fishes have been changed in the past sixteen years. At present there is need for a list which will place the park fish fauna in accord with the latest classifications. Changes in the names of Yellowstone fishes have resulted entirely from fomalities of fish classification and not from correction of any mistakes in identification.

The list following is a comparison of the names given in Smith and Kendall, "Fishes of the Yellowstone National Park," Bureau of Fisheries Document, No. 904, 1921, with the names now used to apply to the same species. In some cases these names have remained unchanged; in others trinomial names are used in preference to binomial; and in still others, generic or specific or both generic and specific names are changed.

Smith and Kendall list sixteen species as being present in the park, and two which were introduced but unsuccessful. These eighteen species are listed; no additions or subtractions are made to Smith and Kendall's list.

Brown and Loch Leven trouts are considered as the same species, only the variety, or subspecies, being different.

Trinomial nomenclature is sometimes applied to the Lake, trout and to the Eastern brook trout; in both cases the subspecific name is a repetition of the specific name.

Cottus punctulatus is a species of the Green River drainage, wherefore it does not appears in Yellowstone.

Perhaps this listing will serve the purpose of aiding those interested in locating more complete references to Yellowstone Park fishes.
