The Warbling Vireo (Vireo gilvus), generally recognized as one polytypic species, is widely distributed across North America, but differences in morphology, song, genetics, and ecology suggest the western and eastern populations may represent two species. Understanding their distributions enables tracking of range changes and other factors that might affect the conservation of populations. Therefore, I studied museum specimens, specimen data, and identifications provided by investigators recording songs to help clarify the ranges of the two taxa in Wyoming. Of 18 specimens in the U.S. National Museum collected from 1858 to 1930, I identify 15 as the western species V. swainsoni. These are spread over most of Wyoming, east to Crook and Albany counties. Only three represent the eastern species V. gilvus, two from Greybull, Big Horn Co., and one from Cheyenne. Whether the overlap represents sympatry of breeding populations in eastern Wyoming or overlap in migration remains to be determined.

Three species of Spilomyia from western North America have been in the Canadian National Collection under the name Spilomyia interrupta Williston, 1882. Two of these are described below as new. Through the co-operation of Mr. Paul Arnaud, then of the U.S. National Museum, I examined the two female syntypes of interrupta and four other specimens of the group. One syntype, labelled “W.J.; Acc. 19702, Williston; Type No. 875, U.S.N.M.; Spilomyia interrupta Will.” on four labels is hereby designated as lectotype; it has been so labelled. The other syntype is a specimen of the species described below as Spilomyia citima n.sp. The other four specimens in the U.S.N.M. are all of interrupta: 1 ♂, Hopland, Calif., Sept.; 1 ♂, Mountains near Claremont, Calif.; 1 ♀, Tuolumne, Calif.; 1 ♀, Medford, Oreg. The C.N.C. contains two specimens of interrupta: 1 ♂, Hopland, Calif., Sept.; 1 ♀, Rowena, Oreg., Sept. 1, 1923 (on flowers of Eriogonum umbellatum). Mr. R. H. Foxlee of Robson, B.C., kindly sent me several specimens for study and donated most of them to the C.N.C.; it gives me pleasure to dedicate one of the new species to him.

In revising the genus Triaspis Haliday, as found in North America north of Mexico, the author studied an undescribed species from Mexico. This form is a parasite of Apion godmani Wagner, a weevil of economic importance. This paper provides a name and a description for this new parasite.The author is most grateful to Dr. V. S. L. Pate of Cornell University for his helpful criticism of the manuscript, and also to Mr. C. F. W. Muesebeck of the U.S. National Museum for the loan of material, and to Dr. Arthur C. Smith of Cornell University for the specimens collected while he was studying the biology of the host in Mexico.

The first systematic study of anal variations found among various Carboniferous crinoids was presented by James Wright (Geol. Mag., lxiii, 1926) and covered Eupachycrinus calyx (McCoy) (now Phanocrinus Kirk) and Zeacrinus konincki Bather. Subsequently (Geol. Mag., lxiv, 1927), the genus Hydreionocrinus, and Ulocrinus globitlaris (Geinitz) (now Ureocrinus Wright and Strimple, Geol. Mag., lxxxii, 1945) were also considered. A total of 2,014 dorsal cups from the Scottish Lower Carboniferous (Mississippian) were involved in the examinations. These specimens were all from strata considered equivalent to the Chester Series (upper Mississippian) of North America. When presenting the genus Phanocrinus Kirk (Journ. Paleont., 11, 1937) recognized the importance of Wright's studies, but noted that examination of an almost equal amount of American material (primarily the Springer collection of the U.S. National Museum) had failed to disclose such great variations. That Kirk was highly impressed by Wright's studies is certain, for in personal conversations, several years ago, he emphasized the potentialities as they might affect my impending studies of Pennsylvanian crinoids. It has, therefore, been with much interest that I have watched similar patterns of development appearing in the large collections being made from both Chester (Upper Mississippian = European upper Lower Carboniferous) and Missouri (Middle Pennsylvanian = European middle Upper Carboniferous) of north-eastern Oklahoma.

We tested the hypothesis that malarial parasites ( Plasmodium and Haemoproteus ) of black-throated blue warblers ( Dendroica caerulescens ) provide sufficient geographical signal to track population movements between the warbler's breeding and wintering habitats in North America. Our results from 1083 warblers sampled across the species' breeding range indicate that parasite lineages are geographically widespread and do not provide site-specific information. The wide distribution of malarial parasites probably reflects postnatal dispersal of their hosts as well as mixing of breeding populations on the wintering range. When compared to geographically structured parasites of sedentary Caribbean songbirds, patterns of malarial infections in black-throated blue warblers suggest that host–malaria dynamics of migratory and sedentary bird populations may be subject to contrasting selection pressures.

Q?rius is an interactive learning venue at the Smithsonian National Museum of Natural History (NMNH) designed specifically for a teen audience. The space gives visitors a chance to interact with museum specimens, especially in the Collections Zone. The Q?rius collections are non-accessioned education collections, belonging to the Office of Education and Outreach (E&O). The collections include the Museum’s seven disciplines – Anthropology, Botany, Entomology, Invertebrate Zoology, Mineral Sciences, Paleobiology, and Vertebrate Zoology. Starting in 2013, collections staff began performing safety assessments on specimens before their rehousing and storage in the publicly accessible Collections Zone. Risks assessed include sharpness, ingestibility, radioactivity, and contaminants (such as arsenic, mercury, and lead, which were historically used in specimen preparation or for pest management). Specimen and object fragility was also assessed. The goal of these assessments was to minimize risks to our visitors and to our collections. The safety assessments allow collections staff to make housing recommendations that would ensure the safety of NMNH’s visitors and the preservation of E&O’s collections in a publicly accessible storage space. This practice now extends to other pre-existing learning venues that contain publicly accessible portions of the E&O Collection, further minimizing risks. Staff have started adding the data gathered by these safety assessments to our collections management system, to protect the data from loss and to make the information easily accessible to staff. This poster relates to a second poster, Establishing Legal Title for Non-Accessioned Collections.

Abstract A series of stationary wave model (SWM) experiments are performed in which the boreal summer atmosphere is forced, over a number of locations in the continental United States, with an idealized diabatic heating anomaly that mimics the atmospheric heating associated with a dry land surface. For localized heating within a large portion of the continental interior, regardless of the specific location of this heating, the spatial pattern of the forced atmospheric circulation anomaly (in terms of 250-hPa eddy streamfunction) is largely the same: a high anomaly forms over west-central North America and a low anomaly forms to the east. In supplemental atmospheric general circulation model (AGCM) experiments, similar results are found; imposing soil moisture dryness in the AGCM in different locations within the U.S. interior tends to produce the aforementioned pattern, along with an associated near-surface warming and precipitation deficit in the center of the continent. The SWM-based and AGCM-based patterns generally agree with composites generated using reanalysis and precipitation gauge data. The AGCM experiments also suggest that dry anomalies imposed in the lower Mississippi River valley have remote surface impacts of particularly large spatial extent, and a region along the eastern half of the U.S.–Canadian border is particularly sensitive to dry anomalies in a number of remote areas. Overall, the SWM and AGCM experiments support the idea of a positive feedback loop operating over the continent: dry surface conditions in many interior locations lead to changes in atmospheric circulation that act to enhance further the overall dryness of the continental interior.
