imately 100 yards wide and one mile long,
around some of the rearing ponds and along the creek at Rock Creek
Hatchery. It has been taken there in association with _Cryptotis parva
parva_, _Blarina brevicauda carolinensis_, _Reithrodontomys megalotis
dychei_, _Peromyscus maniculatus nebrascensis_, _Microtus ochrogaster
haydenii_, and another relic, _Microtus pennsylvanicus finitis_. All
specimens of the newly named bog lemming are from the border zone
between the wet-substrate habitat of _M. p. finitis_ and the drier
habitat occupied by _M. o. haydenii_. Approximately 3000 trap nights
produced the four known specimens.

_S. c. relictus_, like _S. c. paludis_, represents a relict population
of the more southwesterly distribution of the subgenus _Synaptomys_
during Wisconsin and post-Wisconsin times. Additional relict populations
likely will be found in the eastern Great Plains.

The new subspecies is intermediate in some features between _paludis_
and _gossii_. The type locality is separated from that of _paludis_ (14
mi. SW Meade, Meade County, Kansas) by a distance of approximately 220
miles over habitats largely unsuitable for bog lemmings. The nearest
locality of record for S. c. _gossii_ to the east of the type locality
of _relictus_ is at Hunter, Mitchell County, Kansas (see Cockrum, Univ.
Kansas Publ., Mus. Nat. Hist., 7:196, 1952), approximately 200 miles
distant. The locality of record of _gossii_ in Nebraska nearest to the
type locality of _relictus_ is even farther eastward--1 mi. N Pleasant
Dale, Seward County (KU 50188).

_Specimens examined._--Four, from the type locality (KU 51617,
72601-03).

_Transmitted March 11, 1958._
