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... 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...

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...

Perognathus goldmani Osgood and Perognathus artus Osgood from southern Sonora, northern Sinaloa and adjoining parts of Chihuahua and Durango, are two named kinds of the Perognathus intermedius group of pocket mice, of the subgenus Chaetodipus. Until now the two kinds have been treated in the literature as two species. In both goldmani and artus the upper parts are Ochraceous-Buff (capitalized color... more...

A single specimen of little brown bat from the northern part of the state of Veracruz seems to be of an heretofore unrecognized species. It is named and described below.

In preparing maps showing the geographic distribution of North American mammals we have found in the literature conflicting statements and questionable identifications, which have led us to examine the specimens concerned with results as set forth below. Our studies have been aided by a contract (NR 161-791) between the Office of Naval Research, Department of the Navy, and the University of Kansas.... 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...

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...
