Mammalia — Mammals 



The list was largely compiled from Anderson (1946), Ellerman & Morrison-Scott 

 (1951), and Burt & Grossenheider (1952). 



There is great confusion among mammologists concerning the definition of 

 species and subspecies, the North American ones (e.g. Anderson, 1946) as a rule 

 being inclined to assign specific value to rather small taxonomic units. Unfortu- 

 nately no thorough comparison has been made between the Palaearctic and the 

 Nearctic mammal fauna and the relations indicated below are therefore in some 

 cases merely suggestive, especially in the Rodentia, where the opinions of spe- 

 cialists largely disagree. 



The following Old World Rodentia, which according to Ellerman & Morrison- 

 Scott (195 1) "doubtless", "probably" or "perhaps" are represented also in North 

 America, have been omitted pending further evidence: — Clethrionomys glareolus 

 Schreb., Marmota marmota L.^, and Microtus agrestis L.

- This arrangement of northern Sorex is quite tentative. The association of petschorae, 

 middendorffi, and ultimus with tundrensis was made by Chaworth-Muster, according to
