A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz Jan 1941

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …


The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert Jan 1941

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert

Bulletin of the University of Nebraska State Museum (1924–2023)

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.


A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard Jan 1941

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …


A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1941

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).


Preliminary Report On The Legumes Of The Arkansas Uplands, Orrin J. Henbest Jan 1941

Preliminary Report On The Legumes Of The Arkansas Uplands, Orrin J. Henbest

Journal of the Arkansas Academy of Science

A brief discussion is presented on the ecologic, taxonomic, and economic features of the leguminous plants of the uplands occupying the northwestern half of Arkansas. The list of 37 genera and 115 species is compiled from the author's collection and from the specimens in the herbarium of the University of Arkansas collected in this part of the state. The geographic position of this area and its variety of ecological habitats indicate that it may yield nearly 175 species of legumes.

Common Birds Of Southeastern United States In Relation To Agriculture, F. E. L. Beal, W. L. Mcatee, E. R. Kalmbach Jan 1941

Common Birds Of Southeastern United States In Relation To Agriculture, F. E. L. Beal, W. L. Mcatee, E. R. Kalmbach

United States Fish and Wildlife Service: Publications

From a purely practical point of view the most important of the relations of native birds to man are the economic. The esthetic value of birds is great, greater indeed than that of any other group of animals; and that this is a real and especially a treasured value is not to be denied. But it is in their relation to insect and other enemies of crops that birds are most directly associated with the welfare of mankind, and their value in this particular should be made as widely known as possible. This bulletin is one of a series designed …

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann Jan 1941

Phylogenetic Studies On The Blood-Inhabiting Trematodes, Harold Frederick Dieckmann

University of the Pacific Theses and Dissertations

Trematodes belonging to the blood-inhabiting group have long attracted the attention of parasitologists and medical men, especially those trematodos belonging to the family Schistosomidae because throw widely distributed species, Schistosoma Japonicum, S. haematobium, and S. mansoni, are parasitic in man, and in endemic regions are the cause of important human diseases. These schistosomes, with a few exception, have undergone more detailed research than any other trematodes.

Since the discovery of the first digenetic trematode exhibiting sexual dimorphism by Rudolphi (1819), which was named Distoma canaliculatum, and the descriptions of the other blood flukes up until the present time, a vast …


Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking Jan 1941

Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking

University of the Pacific Theses and Dissertations

In 1935 I first visited the Kings Canyon area. Since then I have spent many hours wandering through the woods and over the mountains in the area around the old General Grant National Park and the country which is now included in the Kings Canyon National Park. To my knowledge, no complete flora has been made for this vicinity. I consider the following pages to be the beginning of a fascinating work. It is the beginning because this paper includes only plants with woody stems.
