A New Bog Lemming (Genus Synaptomys)

From Nebraska

BY

J. KNOX JONES, JR.

In the autumn of 1952, I obtained a southern bog lemming, _Synaptomys
cooperi_, at Rock Creek State Fish Hatchery, Dundy County, in extreme
southwestern Nebraska. This locality of record is the westernmost for
the species in North America. Subsequently, I reported this specimen in
the literature (Univ. Kansas Publ., Mus. Nat. Hist., 7:486, 1954),
provisionally assigning it to _Synaptomys cooperi gossii_, the
subspecies occurring in eastern Nebraska. In late November of 1956, J.
R. Alcorn collected three additional bog lemmings at the Rock Creek
Hatchery.

These specimens from Dundy County represent a relict population that
differs in several characteristics from _S. c. gossii_, and that differs
also from all other subspecies of the species. This relict population
is, therefore, here given subspecific recognition.
