In 1884 the genus Tamias, as recorded in Mr. True's 

 List, contained 4 species and 4 additional subspecies; in 

 1894 (taking Tamias as limited in 1884), the recognized 

 forms number 21 species and 12 subspecies. 



The species in the 1884 list were (1) the common Eastern 

 Chipmunk ( Tamias striata s)\n\\\z\i has since been separated 

 into three subspecies; (2) Say's Chipmunk (T. lateralis), 

 ranging from the Rocky Mountains westward, in suitable 

 localities, to the Pacific coast. This now consists of a 

 group of three species and several additional subspecies. 

 (3) Harris's Chipmunk (T. Ziarrissi), more southern in dis- 

 tribution than the last, now stands as a group of 4 species 

 and 2 subspecies. (4) The Four-lined or Rocky Mountain 

 Chipmunk (T. quadrivittatus), with 4 subspecies, now 

 stands as a group of 23 species and 16 subspecies, under 

 several subgeneric subdivisions. 1
