here is 30north american big game with the different sub species

Big horn sheep: stone, dall, desert, and rocky mountain
Bear:brown, grizzly, black, and polar bear
Caribou: barren ground, Quebec-Labrador, mountain, and woodland
Deer: mule, white-tail, black-tail, and coues
Moose: Alaskan-Yukon, Canada, and Shiras
Elk: Roosevelt, rocky mountain, tule, eastern
Bison
Muskox
Puma or Mountain lion
Pronghorn
Walrus
Rocky Mountain Goat

But it all depends on the oranization you are associting with on how many animals there are for example there is the atlantic and pacific walrus that could add another animal. there is also the merriam and manitoban elk not listed above. The sitka black-tail. so as you can see the number can be rather large depending on how many of the subspecies you are harvesting.
hope this helps
