This is not a valid subspecies anymore. Is a synonym of Bison bison bison. At the moment only two subspecies are recognised: Bison bison athabasacae Rhoads, 1898 -- wood bison Bison bison bison (Linnaeus, 1758) -- plains bison According to Wilson & Ruff, eds. (1999), "Recent evidence that environmental influences may explain pelage differences between plains and wood bison, and comparisons of mitochondrial DNA, suggest that subspecific distinction may not be justified. This reassessment has important conservation implications because the presumed subspecies athabascae is listed as endangered." They also suggest that "Although most authorities still favor Bison, several recent reviews have advocated placing American bison in the genus Bos." Still, they retain Bison as a valid genus, and list the two subspecies (Bison bison athabascae and Bison bison bison). www.science.smith.edu/departments/Biology/VHAYSSEN/msi/pdf/i0076-3519-266-01-0001.pdfand: nmnhgoph.si.edu/cgi-bin/wdb/msw/names/query/14211 |

Taxonomy Bison bison [Linnaeus, 1758]. Citation: Syst. Nat., 10th ed., 1:72. Type locality: "Mexico" (= C Kansas, "Quivira"), redesignated as Canadian River valley, New Mexico (USA) The taxonomic record (above) is taken from Wilson and Reeder (1993). Some authors consider Bison bison and B. bonasus to be conspecific, grouping the two into a single species (Nowak, 1991). The taxonomic status of the genus Bison is also disputed, with some authorities placing it as a subgenus of Bos (Nowak, 1991). Two subspecies are generally recognized, the wood bison, B. b. athabascae of northern Canada, and the plains bison . B. b. bison, the great plains of southern Canada and the central United States. Invalid synonyms include americanus, athabascae, haningtoni, montanae, oregonus, pennsylvanicus, and septemtrionalis (Wilson and Reeder, 1993). www.ultimateungulate.com/Artiodactyla/Bison_bison.html |

The pop might well have survived to the late 1830 (1838-1839).
