Comments on Taxonomy
NEW MEXICO: This account includes information regarding the USFS Sensitive species, O.c. virginialis. For information about the other subspecies in the state, see Accounts 010595 and 010590. O.c. virginalis, the state fish of New Mexico, along with the Gila Trout (O. gilae) represent the only extant native salmonids in the state. These natives readily hybridize with other spring spawning trout such as the rainbow trout, and other subspecies of O. clarki (Sublette et al., 1990)*49*.

Oncorhynchus clarki virginalis was described by Girard (1857b) based on specimens collected by members of the Pacific Railroad Survey in 1853 from Ute [Utah] Creek [Rio Grande Drainage] at Fort Massachusetts in the San Luis Valley, Colorado (Sublette et al., 1990)*49*.

COLORADO: SOME CONFUSION SURROUNDING NOMENCLATURE AND TYPE LOCALITY. GIRARD FIRST DESCRIBED SALAR VIRGINALIS FROM UTE CREEK BUT REPORTED UTAH CREEK. COPE IN 1872 DESCRIBED A NEW SPECIES, SALMO SPILURUS FROM FROM SANGRE DE CRISTO CREEK, DISTINCT FROM S. VIRGINALIS. COPE ALSO BELIEVED S. PLEURITICUS OCCURRED IN THE RIO GRANDE DRAINAGE NEAR FORT GARLAND. JORDAN USED VIRGINALIS FOR BONNEVILLE CUTTHROAT AND SPILURUS FOR RIO GRANDE CUTTHROAT. SNYDER, JORDAN AND BEHNKE HAVE CLEARED THE PROBLEM *50*.
