TYPE LOCALITY: Hungary, Budapest, Rakos Plains .

DISTRIBUTION: Hungary, Rumania, Yugoslavia, Bulgaria, and steppes of Crimea and S Ukraine.

SYNONYMS: mehelyi, sergii.

COMMENTS: Subgenus Mus . This is the mouse that constructs soil-covered storage mounds of grain, and was formally known as M. hortulanus (see Corbet, 1984); however, the holotype of hortulanus is actually a M. musculus, so the earliest name for the species is spicilegus (Gerasimov et al., 1990) . Results of morphometric and biochemical analyses were reported by Bonhomme et al. (1984), Petrov and Ruzic (1985), Gerasimov et al. (1990), She et al. (1990), and Lyalyukhina et al. (1991). Other cytogenetic and biochemical contrasts between the species (reported as hortulanus) and M. musculus were recorded by Bulatova and Kotenkova (1990), and Yakimenko et al. (1990).
