 2. Sciurus carolinensis leucotis (Gapper). 



NORTHEASTERN GRAY SQUIRREL. 



Not so common as the next but not rare. It has been observed foraging 

 about garbage barrels on the edge of town. The gray squirrel is most fre 

 quently found in mixed woods, particularly along streams, a sycamore 

 being a favorite abode. Judging from caged specimens of this species, the 

 black form is not rare.

:5. Sciurus ludovicianus Custis. 



FOX SQUIRREL. 



Very common. Unlike the gray squirrel, which is usually found in 

 mixed woods, the fox squirrel is most common in more uniform growths, 

 such as beech, in higher situations. In some places a veritable feud seems 

 to exist between these and the red-headed woodpeckers. The latter have 

 often been observed compelling their larger antagonists to seek safety in 

 flight.

4. Sciurus striatus lysteri (Richardson). 



NORTHEASTERN CHIPMUNK. 



Abundant. An inhabitant of roadsides and fields as well as woods. 

 Indigenous on the University campus where it feeds in autumn upon 

 beechnuts and berries of the Virginia creeper (Parthenocissus quinque- 

 fol'i.a). Specimens are at hand from the Cascades and elsewhere, and it 

 has been observed some distance within the mouth of Mayfield's Cave by 

 Mr. A. M. Banta. 



5. Marmota monax Linn. 



WOODCHUCK. 



Common. A railroad embankment is a favorite location for their bur 

 rows but they also take advantage of the sinkholes so abundant in the 

 limestone of the region. They appear to wander to some extent in late 

 May and early June, and I have found them dead in highways and stock 

 enclosures at this season. In the present year, I have made an observa 

 tion in another locality ( Washington, D. C.) that shows the woodchuck 

 to be somewhat nocturnal at times, one being seen running about at some 

 distance from the burrow and even feeding after nine P. M. (May 19, 1906). 

 Also, Dr. A. K. Fisher and the writer observed one voluntarily swim the 

 Potomac at a point where it is more than a hundred yards wide (July 22, 

 190(5).

0. Sciuropterus volans Linn. 



SOUTHERN FLYING SQUIRREL. 



Common. Indigenous on the University campus and established in a 

 barn-loft and some tree boxes in town. 

 Bloomington.
