. Catalogue of the mammals of Western Europe (Europe exclusive of Russia) in the collection of the British museum. Mammals. 866 RODENTIA posteriorly, finely tuberculate anteriorly ; plantar tubercles small, widely spaced, without noticeable contrasts in size or form, the two anterior slightly the largest, the postero-external slightly the smallest, their outlines ovate or nearly circular; a small but distinct supplemental tubercle at outer margin of tubercles lying at base of first and fifth toes. Claws simple, curved, those on hind feet slightly the larger. Tail about as long as head and body
. Catalogue of the mammals of Western Europe (Europe exclusive of Russia) in the collection of the British museum. Mammals. 866 RODENTIA posteriorly, finely tuberculate anteriorly ; plantar tubercles small, widely spaced, without noticeable contrasts in size or form, the two anterior slightly the largest, the postero-external slightly the smallest, their outlines ovate or nearly circular; a small but distinct supplemental tubercle at outer margin of tubercles lying at base of first and fifth toes. Claws simple, curved, those on hind feet slightly the larger. Tail about as long as head and body, sometimes a little longer, rarely much shorter unless injured, its diameter at base about 3 mm., its tip not so slender as in Apodemus sylvaticus; annulations well defined but narrow, about twenty-two to the centimeter at middle, the boun- daries of the individual scales obscurely marked ; hairs rather numerous but not concealing annulations, and not forming pencil, their length equal to about width of two and a half rings. Fur soft throughout, the grooved hairs so slender as not to suggest bristles in texture. Mammae : p3 — 3; ^ 2 — 2 = 10. Colour.—Upper parts a light, dull wood-brown, irregularly darkened with slaty and blackish along back, faintly more bufFy on sides, the general effect not far from the broccoli-brown of Ridgway, but usually with a peculiar dusky cast; underparts essentially like sides or a little more yellowish, the line of demar- cation absent or very obscure ; bases of hairs everywhere slate- grey, this colour usually appearing at surface on chin and throat, where it produces a smoke-grey or drab-grey effect ; ear dull brownish, the outer side of anterior border usually darker ; feet drab or dusky, not contrasting with back ; tail dull brownish throughout, occasionally lighter below than above. Skull.—As compared with that of small European Muridx of other genera, Micromys excepted, the skull of Mas musculus is immediately recognizable by its sm
