APODEMUS 837 but vr witli no iniiuito anterior cusp on outer side, and lll^ and â m.^ without cingulum-like outer ledge. External characters.âThe general external form is less slender and delicate than in the members of the Apodemus syhciticus group, the ear is shorter, reaching barely to eye, though not peculiar in structure, the feet are more robust, and the tail is relatively shorter and more coai'sely annulated. Palms as in A. syhaticuH, except that the two intermediate tubercles are relatively smaller. Feet with metatarsal portion relatively shorter than in A. sylvatkus, but toes showing no peculiarities. Plantar tubercles rather small, very sharply defined, the postero- external minute and sometimes obsolete ; space between tubercles rugose, though rather less so than in A. sylvatkus. Caudal aunulations very distinct, about fourteen to the centimeter at middle; caudal hairs essentially as in A. sylvatkus but less abundant, the pencil ill-defined. Mannme : p 2 â 2, i 2 â 2 = 8. Colour.âUpper parts a reddish brown between the russet and wood-brown of Ridgway, brighter posteriorly, more didl anteriorly, fading nearly to ochraceous-buft" on sides and cheeks ; ears and face between eyes and muzzzle noticeably tinged with hair-brown; a clear black median stripe about 3 mm. wide extends from region just behind eyes to within about 10 mm. of base of tail; underparts and inner surface of legs dull white clouded by the slaty undercolour ; tail not bicolor, the general efi;ect hair-brown somewhat darker above than below; feet vary- ing from pale drab to dull whitish. The young are essentially like the adults, diflfer- ing only in a slight general dulness of colour. SJiull.âIn general appearance the skull resembles that of Apodemus sylvatkus, but the brain-case is longer and narrower and the rostrum is shorter and more noticeably tapering.
