Smith's vole

Smith's vole (Craseomys smithii) is a species of rodent in the family Cricetidae. It is also known as Smith's red-backed vole and is found only in Japan.

This vole is named after Richard Gordon Smith, (1858–1918) who, after falling out with his wife, traveled the world hunting for animals and keeping a record of his travels and discoveries in eight large leather-bound diaries. He spent some time in Japan where he collected mammals for the British Museum, including the type specimen of this vole.
