LIST OF MAMMALIA 
HITHERTO DETECTED IN THE COUNTRY BETWEEN THE RIDGE OF THE ROCKY MOUNTAINS 
AND THE PACIFIC, 
FROM NORTH CALIFORNIA TO THE NORTHERN EXTREMITY OF THE CONTINENT; 
With references to detailed descriptions in the Fauna Boreali-Americana. 
1 & 2. Vespertilio. Bat. 
Kotzebue found two small bats, with short ears, in Norfolk Sound, lat. 56f N. 
3. Sorex parvus. Small shrew-mouse. (Faun. Bor. Am. No. 5.) 
Killed by Mr. Collie, on the shores of Behring’s Straits. 
4. Scalops Canadensis. Shrew-mole. (F. B. A. No. 6.) 
Common on the banks of the Columbia. 
5. CONDYLURA MACROURA. ThIOK-TAILED STAR-NOSE. (F. B. A. No. 83, p.284.) 
Banks of the Columbia. 
6. Ursus americanus. American black bear. (F. B. A. No. 8.) 
Northern California, New Caledonia, and Norfolk Sound. Its skins are enumerated by 
Langsdorff among those procured by the Russian American Company at Kodiak; but the animal is 
stated by him not to exist on the islands of Alaska. Cook obtained many bear skins of a shining 
black colour on the island of Nootka. 
7. Ursus arctos, Americanus. Barren-ground bear. (F. B. A. No. 9.) 
The brown bear skins of Oonalaska, mentioned by Langsdorff, and the brown or sooty bear skins 
got by Cook in Prince William’s Sound, lat. 61° IF N., were probably the spoils of this species. 
I have not sufficient data for determining whether this American animal ought to be ranked as 
specifically distinct from the European Ursus Arctos, or merely considered as a local variety ; 
hence, to avoid unnecessarily introducing a new specific name, it is given under this appellation. 
8. Ursus ferox. Grisly bear. (F. B. A. No. 10.) 
Northern California, and upper branches of the Columbia. 
9. Ursus maritimus. Polar or sea bear. (F. B. A. No. 10 bis.) 
Prince William’s Sound, and within Behring’s Straits.* 
* Through a mistake, this animal and the walrus are erroneously stated in the Fauna Boreali-Americana not to 
inhabit Behring’s Straits.
