Catalogue of the Mammals of Western Europe (Europe Exclusive of Russia) in the Collection of the British Museum, published in 1912 by Gerrit S. Miller, is a comprehensive scientific work documenting land mammal species found in Western Europe. Authored by Miller, an American zoologist, and published under the British Museum’s Department of Zoology, the book spans over 1,000 pages and details the taxonomy, evolutionary history, physical characteristics, behaviors, and geographic distributions of mammals in the museum’s collection. Initiated with support from Lord Lilford, who funded specimen collection, the catalogue serves as a meticulous reference for zoologists, covering species’ descriptions, measurements, and habitats with illustrations. It remains a significant resource for studying European mammal biodiversity, reflecting early 20th-century natural history scholarship.
