In a collection of mammals obtained in Coahuila, México, there is a series of 24 long-nosed bats, _Leptonycteris nivalis_. These bats have a larger skull and a longer third finger than other bats of this species found to the south of Coahuila. On the basis of these distinctive characters, it seems appropriate to recognize these long-nosed bats from Coahuila as belonging to a new subspecies, named and described.
