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. Myotis elegans new species Holotype.—Female, adult, skin and skull, No. 88398 Museum of Natural History, The University of Kansas; 12-1/2 mi. N. Tihuatlán, 300 ft. elevation, Veracruz, Mexico; obtained on September 24, 1961, by Percy L. Clifton, original No. 985.... 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 magasin de zoologie, 13 (ser. 2): 97, March, 1861)... 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 described and named as follows: Thomomys... 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, Mexico; March 10,... 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 of which previously had been reported by... 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 skull, No. 13045, Univ. Kansas Mus.... more...

The most popular small game mammal in nearly every part of North America is one or another of the species of rabbits or hares. The rabbit is one of the few species of wild game that still is hunted commercially and sold for food on the open market. The close association and repeated contact of man with these animals has resulted in his contracting such of their diseases as are transmissible to him. Consequently the rabbits and hares have figured... more...

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. Grateful acknowledgment is made to the persons... 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...

In preparing maps showing the geographic distribution of North American mammals we have found in the literature conflicting statements concerning the subspecific identity of several rodents. Wherever possible, we have examined the pertinent specimens. Results of our examination are given 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. Also,... more...
