Therefore, the name A[talapha]. mexicana Saussure (Revue et magasin de zoologie, 13 (ser. 2): 97, March, 1861)... more...

IN preparing maps showing the geographic distribution of North American lagomorphs, some conflicting statements in the literature have led us to examine the pertinent specimens of the Florida cottontail and the Audubon cottontail with results as given below. The study here reported upon was aided by a contract between the Office of Naval Research, Department of the Navy, and the University of Kansas (NR 161–791). Unless otherwise indicated,... more...

WHAT species of mammals occur on the "coastal island", barrier beach, of Tamaulipas? Are the closest relatives of these mammals on Padre and Mustang islands of Texas, instead of on the mainland of Tamaulipas, or are the mammals on the barrier beach distinct from all others?

IN 1949, for the Museum of Natural History of the University of Kansas, Mr. John A. White collected two specimens of the species Microtus montanus in the Bitterroot Valley of Montana, that did not fit the description of any named subspecies.

Among small mammals accumulated, from Wyoming, in the Museum of Natural History of the University of Kansas, specimens of the wide-spread species Thomomys talpoides are abundantly represented. Subspecific names are available for most of these, but specimens from the Sierra Madre Mountain Range of Wyoming and Colorado prove upon comparison to pertain to an heretofore unnamed subspecies which may be described and named as follows: Thomomys... more...

In preparing a list of kinds of mammals of which specimens have been saved from the Méxican state of Michoacán, two heretofore unrecognized subspecies of the Méxican meadow mouse, Microtus mexicanus, have been found. Names for these and descriptions are given below. Microtus mexicanus fundatus new subspecies Type.—Male, adult, skin and skull; No. 100637, Univ. California Mus. Vert. Zool.; 3½ mi. S... more...

New name combinations for two kinds of Central American sloths that heretofore have stood in the literature as nominal species are given below, along with the evidence supporting their relegation to subspecific rank. Research assistance has been provided from a contract (NR 161-791) between the Office of Naval Research, Department of the Navy, and the University of Kansas. Bradypus griseus ignavus Goldman Goldman (Smiths. Misc. Coll., 60(22):1,... more...

Five skins with skulls of Rhogeëssa, collected by J. R. Alcorn in the states of Sonora and Nayarit of western Mexico, were recently received at the Museum of Natural History of the University of Kansas. Two other specimens of the same genus, collected by Walter W. Dalquest in the state of Veracruz of eastern Mexico, also are in the Museum of Natural History. With the aim of applying names to these bats they were compared with materials in... more...
