Suhspecific characters. — Similar to Eutamias bulleri hulleri, but sides slightly 
darker; head slightly paler (more grayish); tail darker beneath and edged with 
a darker shade of buff; hind foot shorter; skull smaller. ' 
Measurements of type. — Total length, 234; tail vertebrae, 108; hind foot, 35; 
ear from notch, 17. Skull: Greatest length, 36.6; zygomatic breadth, 19.5; mas- 
toidal breadth, 15.8; interorbital breadth, 8.3; length of nasals, 12.1. 
Remarks. — This race apparently is confined to an isolated mountain range in 
southern Coahuila. It resembles typical hulleri in color, but is readily dis- 
tinguished by the darker color of the under side of the tail. In this character 
it resembles durangce, but differs from that race in the absence of a buffy wash 
on the upper parts. 
Eutamias speciosus sequoiensis subsp. nov. 
30899 
Type. — No. U. S. National Museum (Biological Survey collection); 
female adult, skin and skull; from Mineral King, east fork of Kaweah River, 
California (altitude 7,300 feet); collected September 12, 1891, by Vernon Bailey; 
original number 3259. 
Subspecific characters. — Similar to Eutamias speciosus f rater, but upperparts 
averaging slightly darker, the median pair of dorsal stripes less whitish and more 
mixed with cinnamon; tail and ears averaging slightly longer; tail much darker 
beneath, edged with a paler shade of buff, and with a greater amount of black 
at the tip. Compared with speciosus: Upper parts more brownish and less gray- 
ish in general tone, the median pair of dorsal stripes more mixed with cinnamon ; 
rump and hind feet more buffy (less grayish) ; tail decidedly longer. Compared 
with callipeplus: Upperparts and sides more extensively tawny, the median 
pair of dorsal stripes less whitish; shoulders darker; tail with much greater 
amount of black at the tip; hind feet, ears, and tail longer. 
Measurements of type. — Total length, 241; tail vertebrae, 114; hind foot, 36; 
ear from notch, 18.1. Skull: Greatest length, 36.8; zygomatic breadth, 19.4; 
mastoidal breadth, 14.9; interorbital breadth, 8.2; length of nasals, 12.5. 
Remarks. — The sequoia chipmunk ranges on the upper slopes of the southern 
Sierra Nevada from San Joaquin River south to Tule River and east to Mt. 
Whitney and Olancha Peak. Doctor Merriam referred the series from ‘‘the 
eastern crest of the High Sierra from Olancha Peak and Mount Whitney north- 
ward” to speciosus, and the series from “the western slope of the Sierra from 
the headwaters of Tule River northward nearly to the Yosemite Valley” to 
callipeplus.^ With a much larger series than was then available, I can detect 
no constant differences between these two colonies, but as a whole they show 
marked differences from all the other races, as pointed out above. 
Eutamias townsendii siskiyou subsp. nov. 
Type. — No. 161,033, U. S. National Museum (Biological Survey collection); 
female adult, skin and skull; from near summit of White Mountain, Siskiyou
