Common Shrews of the Yosemite region ; % natural size. 



a. Navigator Shrew, east fork of Indian Caiaon, June 23, 1915. 

 h. Yosemite Shrew, Yosemite Valley, December 29, 1914. 

 o. Dusky Shrew, same data as a. 



The slender nose, inconspicuous eyes and ears, and plush-like pelage all indicate rela- 

 tionship with the moles. The expanded, fringed hind toes of the Navigator Shrew show 

 correlation with its aquatic habits. For discussion of species, see text, pp. 47, 50.
