1 In this gemis the foUowing subgenera have been recently used: Otospermophilus 

 Braxdt (Bull, class, phys.-niatli. rte Tacail. imp. des sci. de St. Petersbourg, ii, p. 379 

 1849), for S. f/rammurus and its allies; Ammospcrmophilus Merkiam (Proc. biol. soc. 

 Washington, vii, p. 27, April 13, 1893), for ,S'. leucurus (type) and related species; 

 Xerosijermophilus Merhia.m (Proc. biol. soc. Washington, vii, p. 27, April 13,1893), for 

 S. »(i,o/(arensJs (type) and the allied species of the spUosoma growYi; CaUospermophUiis 

 Merriam (Proc. biol. soc. Washington, xi, p. 189, July 1, 1877), for S. lateralis; and 

 Ictklomys Allen rMonogr. X. Amer. rodentia, p. 821, August, 1877), for S. tridecem- 

 Uneatus (see Merriam, Science, n. s., II, p. 418, September 27, 1885). As but one attempt 

 (Trouessart, Cat. mamm., pt. ii, pp. 433-441. 1897), has been made to assign the various 

 Xorth American forms to their respective subgenera, and that probably without a 

 study of the group, it seems best to arrange the species alphabetically.
