In the autumn of 1952, I obtained a southern bog lemming, Synaptomys cooperi, at Rock Creek State Fish Hatchery, Dundy County, in extreme southwestern Nebraska. This locality of record is the westernmost for the species in North America. Subsequently, I reported this specimen in the literature (Univ. Kansas Publ., Mus. Nat. Hist., 7:486, 1954), provisionally assigning it to Synaptomys cooperi gossii, the subspecies occurring in eastern Nebraska.... more...

The fruit-eating bats of the genus Sturnira are represented on the North American mainland by two species, S. lilium and S. ludovici. The former, in most areas the smaller of the two, is widely distributed in México and Central America and is common in many places. On the other hand, S. ludovici, described by Anthony (1924:8) from near Gualea, Ecuador, generally has been regarded as rare; insofar as we can determine only 20 specimens of... more...

The first mention of bats in Nebraska possibly was by Harrison Allen, in his "Monograph of the Bats of North America" (1864:14, 20, 30, 35, 42), who listed Nycticejus crepuscularis [= Nycticeius humeralis], Lasiurus borealis, Scotophilus carolinensis and Scotophilus fuscus [both = Eptesicus fuscus], and Scotophilus noctivagans [= Lasionycteris noctivagans], as collected in "Nebraska" (then Nebraska Territory) by J. G. Cooper. Henry W. Setzer (in... more...

In the past several years the United States National Museum has received a large number of mammals from central and southern Korea through the auspices of the Commission on Hemorrhagic Fever of the Armed Forces Epidemiological Board. Among these Korean collections are more than a hundred specimens of a murine rodent originally described as "Micromys speciosus peninsulae" by Oldfield Thomas but currently placed in the genus Apodemus. In attempting... more...

Because military service will interrupt my study of Nebraskan mammals, I am here placing on record certain information on the geographic distribution of several species—information that is thought pertinent to current studies of some of my associates. Most of this information is provided by specimens recently collected by me and other representatives of the University of Kansas Museum of Natural History, although specimens from other... more...


In his "Revision of the pocket mice of the genus Perognathus," Osgood (1900:18-20) reviewed the distribution, as then known, of Perognathus fasciatus and recognized two geographic races—Perognathus fasciatus [fasciatus] Wied-Neuwied in eastern Montana and Wyoming and adjacent parts of North and South Dakota, and Perognathus fasciatus infraluteus Thomas, known only from the type locality at Loveland, Larimer County, Colorado. Later, Cary... more...

The western harvest mouse, Reithrodontomys megalotis, inhabits most parts of the central Great Plains and adjacent regions of tall grass prairie to the eastward, shows a marked predilection for grassy habitats, is common in many areas, and is notably less variable geographically than most other cricetids found in the same region. R. megalotis occurs (see Hall and Kelson, 1959:586, map 342) from Minnesota, southwestern Wisconsin, northwestern... more...

Some of the Pleistocene mammals from San Josecito Cave, near Aramberri, Nuevo León, México, collected by field parties of the California Institute of Technology under the direction of the late Professor Chester Stock, have been reported previously (see Furlong, 1943; Cushing, 1945; Stock, 1950; Hooper, 1952; Findley, 1953; Stock, 1953; Handley, 1955; Jackway, 1958). In 1950, Professor Stock loaned a portion of the San Josecito... more...

Nicaragua occupies a strategic position in Central America with respect to mammalian distributional patterns, but relatively little has been published concerning the fauna of the country and its zoogeographic relationships. The present paper records information on distribution, variation, and natural history of 40 species of bats from Nicaragua, 14 of which are here recorded for the first time from the country. Appended is a checklist of the... more...
