AbstractGirdite, a mineral described byWilliams in 1979 from the Grand Central mine, Tombstone, Cochise County, Arizona, USA, has been re-examined by powder X-ray diffraction, single-crystal X-ray diffraction and electron microprobe. Type material from The Natural History Museum, London and the United States National Museum of Natural History (Smithsonian Institution) was examined. The original description of girdite is shown to have been based upon data obtained from at least two and possibly three different phases, one corresponding to ottoite and another probably corresponding to oboyerite, although the latter itself appears to be a mixture. The discreditation of girdite as a valid mineral species has been approved by the IMA-CNMNC, Proposal 16-G.

This paper presents redescriptions of amphipods in the genus Metopa (Stenothoidae) in the type-collections of the United States National Museum of Natural History, Smithsonian Institution. Typeand paratype-material is used for Metopa spinicoxa and M. stelleri. The material used for M. dawsoni is from a station very close to the type locality, and identified by Barnard, who is the author of the species. We have used material from the Albatross expedition in 1906, identified by Shoemaker, for M. cristata and M. majuscula, both originally described by Gurjanova. All species are redescribed using line drawings, and comparisons with the original texts and figures.Key words:

The collection of the National Museum of Natural History, Smithsonian Institution, Washington, D.C., is second only to that of The Natural History Museum (formerly British Museum of Natural History), London, in the number of type specimens of the superfamily Gelechioidea (Lepidoptera). The Smithsonian houses 1,375 gelechioid types: 1,249 holotypes, 48 lectotypes, 1 neotype, 69 species represented by one or more syntypes, and 8 species represented by one or more pseudotypes (i.e., specimens identified as type by an accompanying label that are unlikely to be the type). Three former curators are responsible for the vast majority of the type specimens: August Busck, J. F. Gates Clarke, and Ronald W. Hodges. We present a list of the species for which a type is deposited in the USNM, organized alphabetically. For each species we provide an abbreviated reference to the original description and label data. This list represents the second contribution to a larger effort to make available information on the Lepidoptera type holdings of the USNM.

The investigation which has led to this description of a new mineral began because of a suggestion by Dr. W. F. Foshag, when on a Visit in 1951 to the Mineral Gallery of the British Museum (Natural History), that a brown cut gemstone exhibited as olivine had perhaps been incorrectly determined. More recently, Dr. Foshag has stated that the idea came from Dr. George Switzer, who as a result of an X-ray powder photograph taken in June 1950 of a similar specimen in the collection of the United States National Museum in Washington concluded that his material was not olivine and was likely to be a new species. The present work would not have been pursued had it been realized at the time that Dr. Switzer intended to continue the study when he had suitable material for analysis.

Scissurella dalli Bartsch, 1903, from the southwestern Atlantic Ocean has been reported at least six times in the malacological literature. However, the species is thus far known only from the original description; it was never fi gured; and the type material is missing from the original repository, the United States National Museum, Smithsonian Institution. In the present study, we examine specimens of a scissurellid collected adjacent to the type locality of Scissurella dalli, and evaluate their identity. These specimens proved to correspond to Scissurella clathrata Strebel, 1908. Even though this species shows some similarity with the original description of Scissurella dalli, the vague description by Bartsch lacking details and even containing contradictory indications, led us to the conclusion that they are not conspecifi c. Thus, Scissurella clathrata is reported for the first time at the type locality of S. dalli, and the latter remains as a nomen dubium.

A total of 67 specimens from the National History Museum, London, UK and from the United States National ParasiteCollection, Beltsville, USA, which had previously been identified as Mesocoelium monas Rudolphi, 1819 from a varietyof definitive hosts (amphibians, reptiles and a fish), were reevaluated using available literature and the keys to nine bodytypes of species developed by Dronen et al. (2012). Fifteen specimens were of insufficient quality to be placed into a bodytype. In the remaining 52, only four body types (mesembrinum, monas, lanceatum, and pesteri) were encountered. Noneof the 52 specimens conformed to either the original description of M. monas by Rudolphi in 1819 or the subsequent re-description by Freitas in 1958. Although some authors have proposed sweeping synonymies of species in the genus re-ducing the number of species to as few as four in a study by Nasir & Dìaz in 1971, the results of the present study suggestthat there are likely numerous species worldwide. The usefulness of some characters in separating species of Mesocoelium is discussed.

AbstractAlloxysta Förster, 1869 (Hymenoptera: Figitidae) type material of 19 nominal species deposited in the Canadian National Collection of Insects (Ottawa, Ontario, Canada) and the United States National Museum of Natural History (Washington, District of Columbia, United States of America) were studied. Nine species are treated as valid: A. australiae (Ashmead, 1900), A. commensuratus Andrews, 1978, A. japonicus (Ashmead, 1904), A. lachni (Ashmead, 1885), A. longiventris Baker, 1896, A. minuscula Andrews, 1978, A. nothofagi Andrews, 1976, A. vandenboschi Andrews, 1978, and A. xanthopsis (Ashmead, 1896). The following synonymies are established: A. affinis (Baker, 1896) and A. quebeci Andrews, 1978 junior synonyms of A. castanea (Hartig, 1841); A. alaskensis Ashmead, 1902 and A. coniferensis Andrews, 1978 junior synonyms of A. macrophadna (Hartig, 1841); A. bicolor (Baker, 1896) and A. anthracina Andrews, 1978 junior synonyms of A. obscurata (Hartig, 1840); A. dicksoni Andrews, 1978 junior synonym of A. pilipennis (Hartig, 1840); and A. leguminosa (Weld, 1920), A. megourae (Ashmead, 1887), and A. rauchi Andrews, 1978 junior synonyms of A. brevis (Thomson, 1862). The type material of A. schlingeri Andrews, 1978 and A. halli Andrews, 1978 could not be found and we consider them as nomina dubia. Alloxysta vandenboschi Andrews is removed from synonymy with A. obscurata and considered a valid species. Comments on the type material are given. Complete redescriptions and images are presented for the valid species.

During a career that spanned four decades, Russian artist Vasily Konovalenko (1929–1989) produced more than 70 sculptures carved from gems, minerals, and other raw materials. As unorthodox, compelling, and masterful as Konovalenko's sculptures are, they had been poorly published and poorly known. They are on permanent display at only two museums in the world: the small and obscure State Gems Museum (Samotsvety) in Moscow, Russia, and the Denver Museum of Nature & Science (DMNS), a major natural history museum in Colorado, the United States. This article examines Konovalenko's life and work, as well as the unusual circumstances that led to the two exhibitions, their role in Konovalenko's relative obscurity, and a recent resurgence of interest.
