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... more...

In the academic year of 1947-48 Montague studied the geographic variation in Thomomys talpoides of Wyoming. His study was based upon materials then in the University of Kansas Museum of Natural History. Publication of the results was purposely delayed until previously reported specimens from certain adjacent areas, especially in Colorado, could be examined. In the autumn of 1950 one of us, Hall, was... more...

A series of 17 pocket gophers of the species Thomomys umbrinus obtained in 1943 from points 3, 4 and 5 miles south of Pátzcuaro proves upon comparison to be an hitherto unrecognized subspecies which is described and named as follows: Thomomys umbrinus pullus, new subspecies Type.—Male, adult, skin and skull; No. 100151, Univ. California Mus. Vert. Zool.; 5 mi. S Pátzcuaro, 7800 ft., Michoacán,... more...

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. These were laid aside until we could examine the additional specimens from Montana in the Biological Surveys collection in the United States National Museum, some... 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? These were questions that Dr. von Wedel of Oklahoma City and I asked ourselves in March of 1950 when we were in southern... more...

Our aim is to bring up to date the list of kinds of bats actually known from Barro Colorado Island, Panamá. In 1952 Samuel T. Dickenson, Marguerite Schultz, George P. Young, and E. Raymond Hall spent the first 17 days of April (except Mrs. Schultz who left on April 8) on Barro Colorado Island. On eight evenings a silk net, 30 feet long and 7 feet high with a ¾-inch mesh, was stretched in an open... more...

When Gerrit S. Miller, Jr., published his "Revision of the North American Bats of the Family Vespertilionidae" (N. Amer. Fauna, 13:1-140, 3 pls., 39 figs. in text, October 16, 1897), the red bat, Lasiurus borealis, was known from the southern half of Mexico but he did not know that the hoary bat, Lasiurus cinereus, also occurred there. Therefore, the name A[talapha]. mexicana Saussure (Revue et... more...

INTRODUCTION Yellow bats occur only in the New World and by most recent authors have been referred to the genus Dasypterus Peters. The red bats and the hoary bat, all belonging to the genus Lasiurus Gray, also occur only in the New World except that the hoary bat has an endemic subspecies in the Hawaiian Islands. The kind of yellow bat first to be given a distinctive name was the smaller of the two... more...

When preparing distribution maps for a revised list of the Mammals of Kansas it became apparent to me that pocket mice of the species Perognathus flavescens from south-central Kansas and adjoining parts of Oklahoma were without a subspecific name. The new subspecies is named and described below. Perognathus flavescens cockrumi new subspecies Holotype.—Female, subadult (P4 moderately worn), skin with... more...

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... more...
