The genus Micromys is now restricted to the HarvestMice. These are regarded as belonging to a single species,M. minutus, which, notwithstanding a wide distribution extend-ing from Britain through the central parts of Europe and Asiato Japan, appears to be subject to surprisingly little geographicalvariation. In all the essential features of its organisation this genusis not unlike Apodemus, and there can be little doubt, althoughthe positive evidence of fossils is not yet forthcoming, that it isdescended from primitive Apodemus-\\ke. ancestors. Micromysis characterised by numerous external and internal featureswhich are apparently the outcome of a peculiar specialisation > Mr Adams writes :— I sent the specimen to Barrett-Hamilton, and he sentme his opinion that it was not a case of superfoetation, but that the two smallembryos had died,

The size is diminutive, and the buildelegant and slender; the weight of an adult is scarcely morethan one-sixth of that of an adult A. sylvaticus) The tail isprehensile (a character unique among British mammals). Inthe large hands and feet the pads are of large size and some-what modified form; they serve apparently, as in many otherclimbing mammals, the purpose of climbing-irons. In theear the antitragus is developed as a large triangular valvewhich, is capable of completely closing the meatus. The eyesare smaller and less prominent than in Apodemus. In the skull(as in many climbing mammals) the brain-case is relativelylarge; the facial region, particularly the rostral part, relativelysmall. The cheek-teeth are essentially like those of Apodemus,but cusp 5 in w^ and n^ (
