Its occurrence in these intermediate localities would afford support to the presumption that it is native in Iceland; but I am indebted to Col. H . W . Feilden for the information that the existence of an indigenous mammal of any kind on the Faroes is very unlikely, since they have undergone an intense, although local, glaciation at a period long subsequent to their present condition as islands. At all events, 3Ius sylvaticus is perhaps the species par excellence of all others inhabiting the Palaearctic Begion which we should most expect to find in such an out-of-the-way island as Iceland. Material examined.-The following is a summary of the material which I have been able to examine. Not only have I had before me the specimens included in my own collection, but the whole of those now in the British Museum have been generously placed at my disposal by the authorities. In addition to these Mr. Gerrit S. Miller, Junior, Assistant Curator of Mammals at the United S'ates National Museum, Washingtou, D.C, has most kindly sent over for my examination 66 examples from the collection in that museum. I have thus had before me a series of, in all, about 580 specimens, many of them prepared in the best modern methods and having also attached to them carefully cleaned skulls.
