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. Support for field work that yielded the specimens reported came from the National Science Foundation, the American Heart Association, Inc., and the Kansas University Endowment Association.
