Eothenomys lemminus Miller, 1899. Proc. Acad. Nat. Sci. Phila., (1898), p. 369.

TYPE LOCALITY: U.S. S. R., R.S.F.S. R., Khabarovsk. Krai, Chukotsk. Nat. Okr., Zaliv Sv. Kresta, S.W. of Egvekinom, "Kelsey Station, Plover Bay, Bering Strait".

DISTRIBUTION: Chukotka Peninsula (N. E. Siberia), west to Lena River and south to Amur River (U.S. S.R.).

COMMENT: Formerly included in Aschizomys; see comments under Eothenomys. Most Russian authors have allocated this species to the genus Alticola, usually as a subspecies of A. macrotis; see Yudin et al., 1976, [Small mammals of the northern Far East,] Nauka Sibir. Otd. Novosibirsk, 270 pp., Gromov and Polyakov, 1977:133, and Gromov and Baranova, 1981: 177. Corbet, 1978:100, provisionally placed it in Eothenomys, calling it an "enigmatic species"; Aimi, 1980, Mem. Fac. Sci. Kyoto Univ. Ser. Biol., 8:35-84, provided additional evidence for this allocation, which is followed here. Bykova et al., 1978, Experientia, 34: 1146-1148, suggested that there may be more than one Siberian species.

ISIS NUMBER: 5301410008070001001 as Aschizomys lemminus.
