Raymond Hall and Keith R. Kelson is a scientific publication written in the early 1950s. This work is focused on the field of mammalogy, specifically dealing with the taxonomy and classification of vole species in Montana. The book presents a detailed examination of a newly identified subspecies of the Microtus montanus, contributing to the understanding of species diversity in this region. In the publication, Hall and Kelson describe the characteristics and morphological distinctions of the newly identified subspecies, named Microtus montanus pratincolus, based on specimens collected in Montana's Bitterroot Valley. They compare this subspecies to related forms, highlighting its smaller size and distinct anatomical features, particularly the shape and inflation of the tympanic bullae. Additionally, the authors discuss the taxonomy of another subspecies, Microtus montanus canicaudus, providing insights into its distribution and morphological characteristics, as well as clarifying previous identification errors. The book emphasizes the importance of precise taxonomical classifications in understanding biodiversity and the characteristics that define specific animal populations in the region.
