FEB., 1912. MAMMALS OF ILLINOIS AND WISCONSIN CORY. 201 



The Southern Golden Mouse occurs within our limits in southern 

 Illinois, where it is not uncommon in small growths of hard-wood timber 

 bordering the cypress swamps. All the specimens in the Museum were 

 taken near Olive Branch, Alexander Co. Kennicott secured specimens 

 in Marion County, which is probably not very far from its northern 

 limit. He says "In some parts of Southern Illinois I found this 

 species to be well known as distinct from the common deer-mouse, 

 under the name of 'Red Mouse. ' . . . I captured two at Murphys- 

 boro and it is not very uncommon near Salem, in Marion County. It 

 is seldom found, if ever, in the northern part of this State. 



"The red mouse appears to be strictly an inhabitant of the forest, 

 like the deer-mouse (Hesperomys leucopus), to which it is closely allied 

 in habits as in form. Farmers who had repeatedly observed this, as 

 well as the deer-mouse, in the woods near Salem, inform me that they 

 never heard of the red mouse on the prairie, though it frequented clumps 

 of hazel bushes at the edges of the prairies. . . . The red mouse 

 is more arboreal in its habits than the deer-mouse. I observed one, 

 when driven from its nest, at once take refuge on a tree, instead of run- 

 ning off on the ground, and I am informed that these mice have fre- 

 quently been seen climbing trees and shrubs. From a gentleman, of 

 Salem, I learn that this, like the deer-mouse, builds nests in the branches 

 of small trees, and that several were found in the tops of hazel bushes, 

 and built neatly, somewhat like a bird's nest, but covered at top with 

 a small opening on the side. . . . The only two specimens of this 

 mouse which I have seen alive, were an old female and a half grown 

 young one, found together in the month of May, in a slight nest formed 

 of soft fibres of bark, and placed on the ground under a log. There 

 was no burrow, either beneath or near the log, though the female 

 had evidently reared her young in this nest. The species probably 

 does not generally burrow at all." (7. c., pp. 87-88.) 



Specimens examined from Illinois : 

 Illinois Olive Branch, Alexander Co., 22. 



Reithrodontomys dychei ALLEN, DYCHE'S HARVEST MOUSE, while 

 not as yet recorded from within our limits, may be looked for in southern 

 and western Illinois, as it has been taken at St. Louis, Missouri (Allen, 

 Bull. Amer. Mus. Nat. Hist., 1895, p. 121), and also at Fairport, Mus- 

 catine Co., Iowa, where Mr. T. Surber secured four specimens during 

 the summer of 1910, which were kindly sent to me for examination. 

 The following characters will readily distinguish this little Mouse from 

 our other species: 



Middle of back brown, sides grayish bujj; under parts white ; crowns
