Résumé

Marmota caligata cascadensis is a larger and darker race, found in the Cascade Mountains of southwestern British Columbia (p. 17). ssp. Marmota caligata cascadensis Howell, 1914, TL: Mount Rainier, Pierce Co., Washington. Plateau, south of Isacha Lake, British Columbia. Marmota caligata nivaria. A large, pale race, found in the Rocky Mountains of southwestern Alberta (p. 17), Mountains near Upper St. Mary's Lake, Glacier Co., Montana. ssp. Marmota caligata nivaria Howell, 1914 TL: Mountains near Upper St. Mary's Lake, Glacier Co., Montana. ssp. Marmota caligata sheldoni, Howell, 1914, Montague Island, Alaska. The smaller size of the Montague Island marmots is the basis for their separate subspecies designation. Skull character differences included more narrow premaillae and a shorter nasals than those of mainland subspecies of hoary marmots. One adult male of Montague Island marmot, collected in May 1905, is housed at the U.S. National Museum, District of Columbia. Marmota okanagana (p. 17). Marmota flaviventris nosophora. Specimens of this form have been taken in only three locations near the southern boundary of Alberta: Waterton Lakes National Park, the Milk River valley, and Lake Newell. All the evidence points to the spread of this marmot into Alberta within the past twenty years. There are no recent signs of the species in the Waterton Lakes Park rock slide, where the first specimen was secured (p. 15).
