Gcixjnipluriil diHtrihiitioii.—Central Europe from Sweden and Finland to the Pyrenees, Alps and Greece, and from Great Britain to Roumania and western Russia; eastern limits of range not known. Diagnosis.—Decidedly larger than Apodcnnis sj/lvaticus sjil- vaticHs, the only member of the group together with which it occurs ; head and body about 100 to 115; tail vertebra? about 105 to 125; hind foot, 23 to 27, most frequently 25; condy- lobasal length of skull, 25 to 28-8 mm. ; skull in old individuals becoming decidedly more angular than that of A. sylvaticus; ear large, its height above meatus about 17 to 19 mm. ; general colour of upfjer parts brighter and more russet than in any of the European races of A. sylvaticus; underparts always whitish, the line of demarcation along sides sharply defined; chest spot usually larger than in A. sylvaticus, frecjuently spreading laterally to form a complete collar. External characters.—As in Apodemns sylvaticus, except for such slight peculiarities as result from the larger size. Colour.—Except for the general tendency toward brighter, more russet tints on the upper ]:)arts, and the constant absence of all trace of brownish wash below, the colour so exactly resembles that of Apodemus sylraticns sylratlcus as to need no detailed description. Slcull and teeth.—In individuals old enough to show con- spicuous wear of the teeth the skull attains a degree of massiveness and angularity never seen in A. sylvaticus. This is especially noticeable in the lachrymal and interorbital regions and on the upper surface of the brain-case. The angularity of the interorbital rims in such specimens is continued for- ward nearly to lachrymal region and is so strongly developed as to produce a slight but evident longi- tudinal furrow along middle of frontal ; poste
