ANNOTATED LIST OF SPECIES. 



Rangifer montanus Seton-Thompson. Mountain Caril)oii. 



Rangifer montamis Seton-Thompson, Ottawa Naturalist, XIII, No. 5, (i, Aug. 11, 1899; 

 Allen, Bull. Am. Mus. Nat. Hist., N. Y., XIII, 1-18, April 3, 1900. 



This large woodland caribou is reported as quite eouimon in northern 

 British Columbia al^out the head waters of the Yukon and for an 

 indefinite distance northward. It does not occur on the coast south of 

 Cook Inlet, but is reported from many points immediately bej'ond the 

 summit of the coast mountains. It prefers the higher ground in 

 summer and is not found along river bottoms like the moose, for 

 which reason few are killed by parties descending the river. Its fiesh 

 is smoked and dried b}^ the Indians for winter food, and when so cured 

 is preferred to all other meat of the country. The hides, like those 

 of the moose, serve the natives for various articles of clothing and a"e 

 utilized especialW for sleeping ro])es.
