1 In this genus the following subgenera have been recently used: Otospermophilus 

 BRAXDT (Bull, class, phys.-math. de 1'acad. imp. des sci. de St. Petersbourg, n, p. 379 

 1849), for S. grammurus and its allies; Ammospermophilits MKRIUAM (Proc. biol. soc. 

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

 Xerospermophilus MERRIAM (Proc. biol. soc. Washington, vii, p. 27, April 13, 1893), for 

 S. mohavensis (type) and the allied species of the spilosoma group ; CaUospermophihis 

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

 Ictidomys ALLEN (Monogr. N. Amer. rodentia, p. 821, August, 1877), for S. tridecem- 

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

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

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

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