1 In this genus the following subgenera have been recently used: Otospermophihis 
Brandt (Bull, class, phys.-inath. de I’acad. imp. des sci. de St. Petersbonrg, ii, p. 379 
1849), for S. grammurus and its allies; Ammospennophlhis Merriam (Proc. biol. soc. 
AVashington, vii, p. 27, April 13, 1893), for S. leucurus (type) and related species; 
Xerosperinophilus Merriam (Proc. biol. soc. M^asbington, vii, p.27, April 13,1893), for 
S. ?Ro/<(xren.sis (type) and the allied species of the group ; Callospermophihis 
Merriam (Iboc. biol. soc. AVasbington, xi, ]>. 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. ii, 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.
