In a collection of mammals obtained in Coahuila, México, thereis a series of 24 long-nosed bats, Leptonycteris nivalis. These batshave a larger skull and a longer third finger than other bats of thisspecies found to the south of Coahuila. On the basis of these distinctivecharacters, it seems appropriate to recognize these long-nosedbats from Coahuila as belonging to a new subspecies, namedand described as follows:
