We are pleased to present their work on vertebrate fossils found in Delaware, a subject that has not before been adequately investigated. Edward M. Lauginiger of Wilmington, Delaware teaches biology at Academy Park High School in Sharon Hill, Pennsyl vania. He is especially interested in fossils from the Cretaceous. Eugene F. Hartstein, also of Wilmington, is a chemical engineer with a particular interest in echinoderm and vertebrate fossils. Their combined efforts on this study total 13 years. They have pursued the subject in New Jersey, Maryland, and Texas as well as in Delaware. Both authors are members of the Mid-America Paleontology Society, the Delaware Valley Paleontology Society, and the Delaware Mineralogical Society. We believe that Messrs. Lauginiger and Hartstein have made a significant technical contribution that will be of interest to both professional and amateur paleontologists. Robert R.

PALEOCENE PRIMATES OF THE FORT UNION, WITH DIS- CUSSION OF RELATIONSHIPS OF EOCENE PRIMATES. By James Williams Gidley, Assistant Curator, United States National Museum. INTRODUCTION. The first important contribution to the knowledge of Fort Union mammalian life was furnished by Dr. Earl Douglass and was based on a small lot of fragmentary material collected by him in the au- tumn of 1901 from a locality in Sweet Grass County, Montana, about 25 miles northeast of Bigtimber.* The fauna described by Douglass indicated a horizon about equivalent in age to the Torrejon of New Mexico, but the presence of unfamilar forms, suggesting a different faunal phase, was recognized. A few years later (1908 to 1911) this region was much more fully explored for fossil remains by parties of the United States Geological Survey and the United States National Museum. Working under the direction of Dr. T. W. Stanton, Mr. Albert C. Silberling, an ener- getic and successful collector, procured the first specimens in the winter and spring of 1908, continuing operations intermittently through the following years until the early spring of 1911. The present writer visited the field in 1908 and again in 1909, securing a considerable amount of good material. The net result of this com- bined field work is the splendid collection now in the National Museum, consisting of about 1,000 specimens, for the most part upper and lower jaw portions carrying teeth in varying numbers, but including also several characteristic foot and limb bones. Although nearly 10 years have passed since the last of this collec- tion was received, it was not until late in the summer of 1920 that the preparation of the material for study was completed. -

Access to cliffs and a glacier route (up Hannabreen) often necessitates crossing blocky talus (here Devonian in foreground) and then possibly a pleasanter route up the moraine on to hard glacier ice. Moraine generally affords a useful introduction to the rocks to be traversed along the glacial margin.

Hippopotamidae is the the sister group to the extinct family Raoellidae, and Hippopotamidae exclusive sister group to Cetacea plus Raoellidae in the analysis that as more closely related to pigs and peccaries (that is, Suina) than to down-weights homoplastic characters, althoughin the equallyweighted cetaceans. However, our reanalysis of a modified version of the data set analysis, another topology was equally parsimonious. In that topology, they used2 differs in retaining molecular characters and demonstrates Hippopotamidae moved one node out, being the sister group to an that Hippopotamidae is the closest extant family to Cetacea and that Andrewsarchus, Raoellidae and Cetacea clade. In neither analysis is raoellids are the closest extinct group, consistent with previous phylo- Hippopotamidae closer to the pigs and peccaries than to Cetacea, the genetic studies2,3. This topology supports the view that the aquatic result obtained by Thewissen et al.1. In all our analyses, pachyostosis adaptations in hippopotamids and cetaceans are inherited from their (thickening) of limb bones and bottom walking, which occur in hippo- common ancestor4. potamids9,10, are interpreted to have evolved before the pachyostosis of To conduct our analyses, we started with the same published matrix the auditory bulla, as seen in raoellids and cetaceans1. -

LATE MIOCENE FISHES OF THE CACHE VALLEY MEMBER, SALT LAKE FORMATION, UTAH AND IDAHO by PATRICK H. MCCLELLAN AND GERALD R. SMITH MISCELLANEOUS PUBLICATIONS MUSEUM OF ZOOLOGY, UNIVERSITY OF MICHIGAN, 208 Ann Arbor, December 17, 2020 ISSN 0076-8405 P U B L I C A T I O N S O F T H E MUSEUM OF ZOOLOGY, UNIVERSITY OF MICHIGAN NO. 208 GERALD SMITH, Editor The publications of the Museum of Zoology, The University of Michigan, consist primarily of two series—the Miscellaneous Publications and the Occasional Papers. Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each is sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, I nsects, Mollusks, and other topics is available.
