The Ground Squirrel, of Lewis and Clark above cited, and to which. 

 Ord's Sciurus troglodytus was applied, included at least two or three 

 species or subspecies and is of too composite a character to make the 

 name of any fixed value. 



"Brown Squirrel Sciurus ." Ord in the foot note reference sur- 

 mises the other Brown Squirrel of Lewis and Clark to be Sciurus hud- 

 sonius and there is no doubt that by this term, which is rather vaguely 

 and loosely applied by Lewis and Clark, they meant to designate the 

 forms of hudsonius found east of the Cascade Mountains, now going 

 under the names, S. hudsonius tichardsoni (Bach.) and S. hudsonius 

 fremonti (Aud. & Bach.).

GENUS DIPUS. 



"Labrador Jerboa Dipus Labrador/us," Turton, Syst. Nat , 1802, 99. 



"Canada Jerboa Dipus Canadensis", Davies, Trans. Lin. Soc., 1798, 157. 



"American Jerboa Dipus Americanus", Barton, Amer. Philos. Trans., 

 1798, 115. 



This trio of names apply, so far as can be ascertained, to one species, 

 the Zapus hudsonius (Zimmerman) Coues (Mon. N. Am. Rod., 1877, 

 461-479.). They may apply in part to the Zapus insignis Miller, 

 (Amer. Nat., 1891, 472, and Proc. Biol. Soc. Washn., 1893, i.), avery dis- 

 tinct species, confined to the more boreal parts of the eastern habitat 

 of hudsonius.
