Views in the 1930s
As background for later developments, this chapter will describe some of the reigning views from the latter 1930s concerning cells, membranes, proteins, and metabolic systems. A brief account of some of the methods then available is also included.
Some Pliocene Fishes from Kansas, Oklahoma, and Nebraska
served in dead specimens are the series of bright blue streaks on the scaleless portions of the dorsal and dorsolateral surfaces, the white anterior edge of the first dorsal fin, the silvery tongue, and the dark vertical bands on the dorsolateral surfaces, the latter seen only in feeding skipjack. The two size groups schooled together. School disruption occurred only during feeding. The fish swam with their mouths constantly agape. They were never observed to stop swimming. No rheotaxis was demonstrated.
A Kansas Pleistocene Herpetofauna
THE following report is based on specimens collected by field parties of the University of Michigan Museum of Vertebrate Paleontology (UMMVP), under the direction of Dr. Claud W. Hibbard, during the summers of 1947, 1951 and 1952, these specimens are now contained in the collection of that institution. They were recovered from a deposit in the Kingsdown Formation (considered a local unit of the Sanborn Formation by Frye and Leonard, 1952) of Meade County, Kansas. The fauna of this deposit has been termed the Jinglebob Fauna by Hibbard (1953). As indicated by van der Schalie (1953), this fauna is tentatively correlated with the Sangamon interglacial. The invertebrates have been discussed by van der Schalie (op. cit.), certain mammalian elements of the fauna were described by Rinker (1949), and Oelrich (1953) has described a new species of Terrapene. I wish to express my gratitude to Dr. Hibbard for the opportunity to examine these specimens and prepare this report thereon, and for other assistance he has provided during the course of this study. I also wish to thank Dr. Edward H. Taylor, of the University of Kansas Natural History Museum, for permission to examine comparative skeletal material in the collection of that institution and in his personal collection, and for the many helpful suggestions and other assistance he has offered.
