A New Subspecies of Microtus montanus from Montana and Comments on Microtus canicaudus Miller

"A New Subspecies of Microtus montanus from Montana and Comments on Microtus canicaudus Miller" by E. Raymond Hall is a science publication that focuses on the study of mammals, especially the classification of vole species in Montana. The work introduces a newly recognized subspecies of the Microtus montanus, and its scientific name is Microtus montanus pratincolus; this identification aids in the concept of species diversity within the region. Hall and Kelson explain the features and physical differences of this subspecies, based on examples found in Montana's Bitterroot Valley. They compare it to related subspecies, noting its smaller size and unique features, especially the shape and inflation of the tympanic bullae. The authors also discuss the taxonomy of Microtus montanus canicaudus, giving information about its distribution and physical characteristics, and clearing up past identification mistakes. The aim of the study is to show how important correct classification is to knowing what makes up the wildlife and what to call animals in the region.
