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 […]

Early in 1960 an unusual opportunity arose to carry on biological field work in the midst of virgin rainforest in southern El Petén, Guatemala. At that time the Ohio Oil Company of Guatemala had an air strip and camp at Chinajá, from which place the company was constructing a road northward through the forest. In […]

Information about osteological changes in the groups of reptiles that gave rise to mammals is preserved in the fossil record, but the musculature of these reptiles has been lost forever. Nevertheless, a reasonably accurate picture of the morphology and the spatial relationships of the muscles of many of these extinct vertebrates can be inferred by […]

In 1931 and 1932, H. H. Lane, C. W. Hibbard and W. K. McNown collected the specimens that Hibbard (1933) described and made the basis of two new species. These were from the Rock Lake shale member of the Stanton formation, six miles northwest of Garnett, Anderson County, Kansas. In 1954, from a locality (KAn-1/D, […]

Laws recently enacted by most of the states for the better protection of the game, imposing a nominal license for the privilege of hunting it, have enabled us to take a census, as it were, of that vast number of the American people who enjoy the health-giving sports of the field. This census reveals the […]

The hybrid fishes described herein are _Chrosomus erythrogaster_ (Rafinesque) × _Notropis cornutus frontalis_ (Agassiz), _C. erythrogaster_ × _Semotilus atromaculatus_ (Mitchill), _Campostoma anomalum plumbeum_ (Girard) × _S. atromaculatus_, _Gila nigrescens_ (Girard) × _Rhinichthys cataractae_ (Valenciennes), and _Notropis venustus venustus_ (Girard) × _Notropis whipplei_ (Girard). Two of the combinations have been reported, without descriptions, in literature (citations […]

AN ALLEGED humorist once proposed the query, “Are all fishermen liars, or do only liars go fishing?” This does not seem to me to be funny. It is doubtless true that a cynical attitude of suspicion and doubt is often exhibited on the recital of a fishing exploit. I believe the joke editors of magazines […]

This report concerns the ability of fish-populations in the Neosho and Marais des Cygnes rivers in Kansas to readjust to continuous stream-flow following intermittent conditions resulting from the severest drought in the history of the State. The variable weather in Kansas (and in other areas of the Great Plains) markedly affects its flora and fauna. […]

The Wakarusa River rises in the eastern edge of the Flint Hills and flows approximately 50 miles in an easterly direction and empties into the Kansas River near Eudora; with its tributaries, the Wakarusa drains 458 square miles in parts of Wabaunsee, Shawnee, Osage, and Douglas counties of northeastern Kansas (Fig. 1). The average gradient […]

The Big Blue River in northeastern Kansas will soon be impounded by the Tuttle Creek Dam, located about five miles north of Manhattan, Kansas. Since the inception of this project by the U. S. Army Corps of Engineers much argument has arisen as to the values of the dam and reservoir as opposed to the […]
