Since the method of treating snakebite-poisoning by hypodermic injections of strychnine, discovered by the writer and published but a few years ago, has already been adopted by the medical profession throughout the Australian colonies, and practised even by laymen in cases of urgency with much success, it has been repeatedly suggested to him that the […]

The common garter snake (_Thamnophis sirtalis_) has by far the most extensive geographic range of any North American reptile, covering most of the continental United States from the Atlantic to the Pacific and from south of the Mexican boundary far north into Canada and southeastern Alaska. Of the several recognized subspecies, the eastern _T. s. […]

The systematic status of the populations of lizards assignable to _Cnemidophorus sacki_ in western México (Sonora southward to Jalisco) has been reviewed in detail by Zweifel (1959, Bull. Amer. Mus. Nat. Hist, 117 (2):57-116), who stated that the use of the specific name _sacki_ for the western populations rests upon a reasonable, but as yet […]

The Sacramento Mountains Salamander, _Aneides hardii_ (Taylor), is a plethodontid of relict distribution in the spruce-fir vegetational formation from 8500 to 9600 feet elevation in Otero and Lincoln counties, New Mexico. The salamanders on which most of this report is based were collected three, four, and six miles northeast of Cloudcroft in the Sacramento Mountains. […]

Natural History of Cottonmouth Moccasin, Agkistrodon piscovorus Objectives of the study here reported on were to: (1) learn as much as possible concerning the natural history and economic importance of the cottonmouth; (2) determine what factors limit its geographic distribution; (3) determine the role of the cottonmouth in its ecological community; and (4) compare the […]

In 1954, two of us (Jones and Byers) collected reptiles and amphibians in Korea incidental to field studies relating to hemorrhagic fever. The 382 specimens thus obtained were deposited either in the Museum of Natural History of The University of Kansas (KU), or in the Museum of Zoology of the University of Michigan (UMMZ), and […]

Preparation of a handbook of reptiles and amphibians by the junior author has led to a survey of the collections of these animals at Kansas State Teachers College in Emporia. Numerous locality records of interest and importance have been accumulated there through the efforts of the senior author and a number of his students, particularly […]

Few regions in Middle America are so important zoogeographically as is the Isthmus of Tehuantepec, that neck of land connecting North America with Central America, separating the Pacific Ocean from the Gulf of Mexico by a distance of only about 220 kilometers (airline), and forming a low break between the highlands of México and those […]

In trying to determine the ancestral relationships of modern orders of Amphibia it is not possible to select satisfactory structural ancestors among a wealth of fossils, since very few of the known fossils could even be considered possible, and scarcely any are satisfactory, for such a selection. The nearest approach thus far to a solution […]

For almost 30 years North American herpetologists have been making extensive collections of reptiles and amphibians in México. Some parts of the country, because of their accessibility, soon became relatively well known; other regions lying off the beaten path were bypassed or inadequately sampled. Principally in the last decade herpetologists have been entering regions from […]
