Tamias asiaticus (GMELIN) ALLEN. 
Var. quadrivittatus? 
ROCKY MOUNTAIN CHIPMUNK. 
PLATE IX, FIG. 21. 
T. asiaticus is known to occur in the state from well authen- 
ticated skins collected by T. S. Roberts near Duluth and from 
observations made by Mr. Upham near Red Lake, indicating 
that the species ranges nearly entirely across the state to a 
considerable distance south of the boundary. The specimens 
of Mr. Roberts are not now before me, but several examples 
collected by myself in Canada, along the north-eastern shore 
of Lake Superior, probably are identical. Along the north 
shore this species is much more common than its larger rival 
and conforms with great satisfaction to the conditions of exist- 
ence presented by the rocky soil and depauperated vegetation. 
It was never observed to climb, though carefully watched, 
where it was quite abundant and fearless. Several individuals 
visited our store-tent daily and gave us abundant opportunity 
to observe the activity and pert, pretty ways in whict it out- 
does the familiar species. 
The following table presents the available measurements, all 
being taken from animals collected at Michipicoten bay, Lake 
Superior, during July and August:

These measurements are below the average of T. quadrivittatus 
but the bright coloration points in that direction. 
The characters of var. quadrivittatus are given as follows: 
“Length of head and body, 4.50—5.00; of tail toend of vertebree, 
about 3.50; to end of hairs, about 4.50. Pattern of coloration 
strictly the same as var. borealis, but the colors brighter, with 
much more rufous, and the size smaller. Under parts sometimes 
faintly tinged with fulvous. The black dorsal stripes are edged 
and more or less mixed with rufous; the light stripes, especially
