Tropical fruit-eating bats of the genus Artibeus reach their northernlimits on the lowlands of the eastern and western coasts ofMéxico. Recent students have placed the species of MexicanArtibeus in two groups; one includes bats of small size and oneincludes 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 thelarge species (A. hirsutus, A. jamaicensis jamaicensis, and A. lituratuspalmarum) have been reported as far north as Jalisco along thewest coast. A. cinereus phaeotis and A. turpis nanus are knownfrom as far north as southern Sinaloa, and A. hirsutus is known fromas far north as southern Sonora (Hall and Kelson, 1959:140, 141).Additional specimens of A. hirsutus from Sonora, Sinaloa, andChihuahua, and specimens of A. lituratus and A. jamaicensis fromSinaloa that extend the known ranges of these two species northwardare reported here; data on variation, distribution, and reproductionconcerning these three species are included. Also,specimens of Sturnira lilium and of the genus Chiroderma fromChihuahua that extend their known ranges northwestward arereported.
Support for field work that yielded the specimens reported came from theNational Science Foundation, the American Heart Association, Inc., and theKansas University Endowment Association. Catalogue numbers of The Universityof Kansas Museum of Natural History are cited. The latitude (N)and longitude (W) are recorded to the nearest minute for each localitymentioned.
Artibeus lituratus palmarum J. A. Allen and Chapman.—Specimensfrom Eldorado (24°19', 107°20'), Sinaloa, extend the knownrange of the species approximately 265 miles northwestward fromHuajimic (21°37', 104°21'), Nayarit. Skins and skulls of 11 specimens(75211-75221, 7 males and 4 females) taken on November 13,1957, 1 mi. S Eldorado, were prepared by William L. Cutter.Skeletons of 12 specimens (75222-75233, 3 males and 9 females)from Eldorado were obtained by Cutter on the same day. Noneof the 13 females was pregnant. One specimen (75211, female)is immature; it has open phalangeal ephiphyseal sutures (as dofour other larger individuals); this specimen measured 83 mm. intotal length, weighed 45 grams, and has a skull 26.6 mm. in greatest[Pg 4]length, 22.4 mm. in condylocanine length, 13.4 mm. in lambdoidalbreadth, and has unusually small second (last) upper molar teeth,each having about one half the
