Mus musculus muralis Barrett-Hamilton, 1899

St. Kilda house mouse



Taxonomy & Nomenclature

Synonym/s: Mus muralis Barrett-Hamilton, 1899


Conservation Status


Last record: August 1931


The St. Kilda House mouse (Mus musculus muralis) had become so dependent on people as a food source that when they evacuated the island in 1930 the mouse could not support itself and the species went extinct shortly afterwards. As it may have been artificially translocated to the archipelago there has been some dispute as to its taxonomic status/validity.
