This is an organ that served a purpose in the distant ancestor of an organism, but is not longer pertinent in the presently existing, recently evolved, organisms.
An example would be the muscles we have that can move our ears a bit. Since human ears cannot be reorientated like some animals can (and presumably our long gone ancestors from million of years ago) then those muscle do not serve much purpose (except for mild entertainment).
