L.; [eds.], New Mexico Geological Society 30th Annual Fall Field Conference Guidebook, 310 p. This is one of many related papers that were included in the 1979 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

    Carnivora from the Late Miocene Love Bone Bed of Florida

    Bull. Fla. Mus. Nat. Hist. (2005) 45(4): 413-434 413 CARNIVORA FROM THE LATE MIOCENE LOVE BONE BED OF FLORIDA Jon A. Baskin1 Eleven genera and twelve species of Carnivora are known from the late Miocene Love Bone Bed Local Fauna, Alachua County, Florida. Taxa from there described in detail for the first time include the canid cf. Urocyon sp., the hemicyonine ursid cf. Plithocyon sp., and the mustelids Leptarctus webbi n. sp., Hoplictis sp., and ?Sthenictis near ?S. lacota. Postcrania of the nimravid Barbourofelis indicate that it had a subdigitigrade posture and most likely stalked and ambushed its prey in dense cover. The postcranial morphology of Nimravides (Felidae) is most similar to the jaguar, Panthera onca. The carnivorans strongly support a latest Clarendonian age assignment for the Love Bone Bed. Although the Love Bone Bed local fauna does show some evidence of endemism at the species level, it demonstrates that by the late Clarendonian, Florida had become part of the Clarendonian chronofauna of the midcontinent, in contrast to the higher endemism present in the early Miocene and in the later Miocene and Pliocene of Florida.

Xinjiangchelyids provide us with great insights into the plesiomorphic anatomy of crown-cryptodires, the most diverse group of living turtles, and they are particularly relevant for understanding the origin and early divergence of the primary clades of extant turtles. Results: Exceptionally complete new xinjiangchelyid material from the ?Qigu Formation of the Turpan Basin (Xinjiang Autonomous Province, China) provides new insights into the anatomy of this group and is assigned to Xinjiangchelys wusu n. sp. A phylogenetic analysis places Xinjiangchelys wusu n. sp. in a monophyletic polytomy with other xinjiangchelyids, including Xinjiangchelys junggarensis, X. radiplicatoides, X. levensis and X. latiens. However, the analysis supports the unorthodox, though tentative placement of xinjiangchelyids and sinemydids outside of crown-group Testudines. A particularly interesting new observation is that the skull of this xinjiangchelyid retains such primitive features as a reduced interpterygoid vacuity and basipterygoid processes.

POVAR, CONSULTING EDITOR ELVA MATHIESEN, ASSISTANT EDITOR ALLAN M. SCHRIER, FOUNDING EDITOR, 1962-1987 Published Quarterly by the Schrier Research Laboratory Psychology Department, Brown University Providence, Rhode Island ISSN 0023-6861 POLICY STATEMENT The Laboratory Primate Newsletter provides a central source of information about nonhuman primates and re- lated matters to scientists who use these animals in their research and those whose work supports such research. The Newsletter (1) provides information on care and breeding of nonhuman primates for laboratory research, (2) dis- seminates general information and news about the world of primate research (such as announcements of meetings, research projects, sources of information, nomenclature changes), (3) helps meet the special research needs of indi- vidual investigators by publishing requests for research material or for information related to specific research prob- lems, and (4) serves the cause of conservation of nonhuman primates by publishing information on that topic. As a rule, research articles or summaries accepted for the Newsletter have some practical implications or provide general information likely to be of interest to investigators in a variety of areas of primate research. However, special con- sideration will be given to articles containing data on primates not conveniently publishable elsewhere. General descriptions of current research projects on primates will also be welcome. The Newsletter appears quarterly and is intended primarily for persons doing research with nonhuman primates. Back issues may be purchased for $5.00 each.

    Species Were Accidentally Lost,But Future Shipments Will Probably

    59.9(728) Article XXXIV.- MAMMALS FROM NICARAGUA. BY J. A. ALLEN. During the last two years the Museum has received several collections of birds and mammals from Nicaragua, made by Mr. William B. Richardson, who for many years was in the employ of Messrs. Salvin and Godman as an ornithological collector in Mexico and Central America. The mammals thus far received comprise about 400 specimens, representing nearly 60 species, of which about one-fourth appear to be undescribed. This is perhaps not surprising, in view of the fact that very few mammals have been previously received from Nicaragua. The most important of Mr. Richardson's discoveries are a new and very distinct species of Bassaricyon, and a new species of spiney rat, allied to the Ecuadorian Echimys gymnurus Thomas, and representing a hitherto unrecognized genus. The collection contains also several other species which are quite differentt from any previously known. Mr. Richardson's collecting trips have covered a wide extent of country. From his home at Matagalpa, in the central part of Nicaragua, he visited the highlands to the northward and northwestward, and also the Pacific coast; eastward his explorations extended from Lake Nicaragua to the vicinity of the Atlantic coast. The principal points at which collections were made are as follows: Matagalpa, altitude about 3000 feet. San Rafael del Norte, altitude about 5000 feet. Ocotal, altitude about 4500 feet. Chinandega, on the Pacific slope, about 700 feet. Chontales, lowlands east of Lake Nicaragua, altitude about 500 to 1000 feet. Tuma and Lavala, east of Matagalpa, on the Atlantic slope, below 1000 feet.

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti­ tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com­ mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes­ sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in­ terested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.
