. Wild animals of Glacier National Park. The mammals. Glacier National Park (Agency : U. S. ); Mammals; Birds. 100 WILD ANIMALS OP GLACIER NATIONAL PARK. Masked Siieew: Sorex personatus I. Geoffroy St. Hilaire.—These are the smallest shrews in the park, adult specimens measuring in millimeters: Total length, approximately 100; tail, 10; hind foot, 12. In color they are plain sepia brown, slightly paler below, and •^'ery similar to both the dusky and the Dobson shrews in sum- mer pelage. Their small size, however, usually serves to identify them in the field, but their habits apparently do- not differ much from those of the other two species. In 1895 Howell and I col- lected three specimens at St. JMary Lake on the same ground with a larger series of the dusky shrew, and no difference in the habits of the two could be discovered. Another specimen collected at Mc- Donald Lake and others in country surrounding the park would indicate a distribution over the whole park area in suitable situa- tions. Generally they are forest dwellers, but may be found in meadows or along the streams and out in the prairie and Plains country, and while so ininute as rarely to be noticed, they are prob- ably much more common than is generally supposed. Order CHIROPTERA: Winged Mammals. Family VESPERTILIONID^: Bats. Long-legged Bat: Myotis lucifugus longicrus (True).—A small quick-flying brownish bat seen commonly about the hotel at Lake McDonald on still evenings in August was probably of this species, which Howell and I found abundant a t Flathead Lake in 1895 and of which we col- lected a large series of specimens. Xone were collected in the park, as they were seen only while flying about the hotels. Evidently they had made their homes in dark corners and crevices of the build- ings, from which they emerged at dusk to begin their evening flight in pursuit of winged insects. They circled rapidly about the buildings, under the piazzas, and occasionally through the open doors, and we
