The cave myotis (Myotis velifer) is a colonial, cave-dwelling bat distributed from the southwestern United States to Honduras. I captured an adult, polydactylous female M. velifer at Fort Hood Army Installation, north-central Texas, on 26 July 2006. The bat had seven toes on her left foot and five toes on her right foot. The supernumerary toes appeared normally articulated and developed, and they were voluntarily controlled by the bat. I observed no other polydactylous M. velifer on Fort Hood. This is the second known occurrence of polydactyly in this species.
