[Pokemon] What's a mouse?

I was browsing my Pokedex, and it said Pikachu is the "Electric Mouse" pokemon. I know about electricity, but what's that other word?

Mouse is the common name of a genus of pokemon including: rattata; raticate; pikachu; raichu; sandshrew; sandslash; cyndaquil; pichu; marill; bidoof.

This is part of an old taxonomy in which the mouse genus was defined to include species that scientists believed were closely related to Rattata.
