R 16 British Columbia. 1921 



A revision of the genera of bats of the family Vespertilionidre was made by Gray in -183S, 

 where he abandoned his earlier plan and adopted the main divisions introduced by Spix in his 

 " Simiarum et Vespertilionum Brasiliensium Species Novae," published in 1S23. 



Peters in 1S65 divided the group into 10 families and subfamilies, containing 59 genera. 



Dr. Dobson described 401 species, SO genera, and 14 families and subfamilies when he 

 published his Catalogue of the Chiroptera in the British Museum, 1S7S. 



In 1904 Trouessart recorded Sol species, 122 genera, and 18 families and subfamilies, while 

 Gerrit S. Miller, Jr., whose revision of the North American bats of the family Vespertiliouid;e 

 was published by the United States Department of Agriculture (Division of Biological Survey), 

 October 16th, 1S97, as " North American Fauna " No. 13, and ten years later while Assistant 

 Curator, Division of Mammals, United States Museum, after examining the material in all the 

 leading museums of Europe and America, wrote his work on the " Families and Genera of Bats," 

 published as Bulletin 57 by the Smithsonian Institute, in which he concluded at that time 

 among the known species at least 173 genera and 36 families should be recognized, being also 

 of the opinion that probably the total number of recognized bats will eventually exceed 2,000 

 named forms.

The Life-iiistory and Distribution of Marmots. 



True marmots inhabit the northern portions of both the Old and New Worlds; in the 

 sou I hern portions of their range in the Old World these mammals are found only at considerable 

 elevation above sea-level, hul in more northern districts like the Siberian steppes they are found 

 mi the lowland plains. 



The districts inhabited by all the Old World species, being desolate and barren, are usually 

 subject to intense heat in summer and cold in winter.
