                                                Excerpt.....Tropical fruit-eating bats of the genus Artibeus reach their northern limits on the lowlands of the eastern and western coasts of México. Recent students have placed the species of Mexican Artibeus in two groups; one includes bats of small size and one includes bats of large size (Dalquest, 1953:61; Lukens and Davis, 1957:6; and Davis, 1958:163). Three of the small species (A. cinereus phaeotis, A. aztecus, and A. turpis nanus) and three of the large species (A. hirsutus, A. jamaicensis jamaicensis, and A. lituratus palmarum) have been reported as far north as Jalisco along the west coast. A. cinereus phaeotis and A. turpis nanus are known from as far north as southern Sinaloa, and A. hirsutus is known from as far north as southern Sonora (Hall and Kelson, 1959:140, 141). Additional specimens of A. hirsutus from Sonora, Sinaloa, and Chihuahua, and specimens of A. lituratus and A. jamaicensis from Sinaloa that extend the known ranges of these two species northward are reported here; data on variation, distribution, and reproduction concerning these three species are included. Also, specimens of Sturnira lilium and of the genus Chiroderma from Chihuahua that extend their known ranges northwestward are reported. Less
