1841. _Arvicola scalopsoides_ Audubon and Bachman, Proc. Acad. Nat.
Sci. Philadelphia, 1:97, type from Long Island, New York.
1912. _Pitymys pinetorum scalopsoides_ Miller, U. S. Nat. Mus.
Bull., 79:229, December 31.
Hanson (Trans. Wisconsin Acad. Sci., Arts, and Letters, 36:124, 1944)
reported two pine mice from near Prairie du Sac, in Westpoint Township,
Columbia County, Wisconsin, as _Pitymys pinetorum scalopsoides_ but
cast doubt upon their subspecific identity. He also reported pine mice
from Blue Mounds, Dane County, Wisconsin. We have examined these
specimens (Westpoint, Columbia County, 2--No. 544, skin only, UWDEZ,
and No. 521, skin only, H. C. Hanson's private collection; Westpoint,
Dane County, 1, No. 11620, UWZM; Vermont, Dane County, 2, Nos. 11674
and 11694, UWZM) and have compared them with topotypes of _P. p.
schmidti_, and with specimens of _P. p. nemoralis_ and _P. p.
scalopsoides_. The specimens from Columbia and Dane counties differ
from _P. p. schmidti_ in the greater zygomatic breadth, and lesser
height of skull. They differ from _P. p. nemoralis_ of comparable age
in shorter tooth-row and generally smaller skull. The interorbital
region, however, is wider. In all of the features mentioned above, the
specimens in question agree with _Pitymys pinetorum scalopsoides_, to
which subspecies they are here referred.
