ern shore of Lake Superior, though it reaches northern ^Minnesota, 
as attested by a specimen from Two Harbors, north of Duluth. 
In this connection I have examined specimens from extreme 
northern Wisconsin, near the Hne of the upper peninsula of 
Michigan, the western and south-central part, and the extreme 
southeastern corner. A speciman from Hebron, Jefiferson 
County, is the nearest approach to Scmriis h. loqitax but from 
Its large size and light color is easily referable to minnesota, the 
range of which form, as defined by Dr. Allen in his original 
description, extends to northern Indiana.^ 
Eutamias borealis neglectus Allen. 
Lake Superior Cliipmnnk. 
Although apparently restricted at the present time to the most 
northern counties this chipmunk formerly occurred in the central 
portions of the state. Moses PJarrett gives some interesting notes 
on the two species of chipmunks in central Wisconsin in the early 
fifties.- In the National Museum are four specimens of neglectus 
collected by Dr. E. A. Mearns at Camp Douglas, Juneau County, 
in 1890 and 1891. 
Citellus franklini (Sabine). 
Franklin Spermophile. 
This species is common in isolated colonies in various parts 
of W^alworth County. I have collected many specimens near 
Delavan. The largest colonies here are located on Ridge Prairie, 
just west of town, and on the border of the Big Marsh, seven 
miles north of Delavan on the Whitewater road. In the former 
place the "gray gophers" do considerable damage in the grain 
fields and have greatly increased in numbers in recent years. On 
the Big ^larsh I once shot one from a considerable height in a 
tamarack tree, mistaking it for a gray squirrel. 
The Biological Survey also has records of this species from 
Janesville, Kansasville, Madison, Plover, Racine, Ripon, and 
Whitewater. 
Castor canadensis Kuhl. 
Beaver. 
The beaver was not always confined to the northern coun- 
ties but occurred in the early days over much of the state. Lap- 
ham states that ''the last beaver killed, in the southern part of 
Wisconsin, was in 1819, on Sugar Creek, Walworth County, a, 
very large one."^
