    NOTES ON SOME UPPER MIOCENE SHREWS FROM OREGON
    (Museum of Natural History, University of Oregon, 1966-03) Hutchison, John Howard
    Skull Springs and Quartz Basin, two localities of Barstovian (late Miocene) age in Malheur County, Oregon, have produced relatively abundant jaws and teeth of shrews (family Soricidae Gray). The subfamily Heterosoricinae Viret and Zapfe is represented m these localities by Heterosorex Gaillard, sp., Paradomnina relictus gen. n. et sp. n., and lngentisorex tumididens gen. n. et sp. n. The subfamily Soricinae Murray is represented by the specialized Alluvisorex arcadentes gen. n. et sp. n. The subfamily Crocidurinae Milne Edwards is represented by cf. Limnoecus Stirton, sp. indet.

    PEROMYSCUS OF THE LATE TERTIARY IN OREGON
    (Museum of Natural History, University of Oregon, 1967-06) Shotwell, J. Arnold
    Samples of Peromyscus from six late Tertiary localities in Oregon are described. Variation and progressive changes are discussed for the time, Barstovian through Hemphillian. Two new species, P. pagei and P. valensis are described. The diversity of late Tertiary species in Oregon and the Northern Great Basin is compared with that of living species in North America today.
