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.

Specimens of the interesting new species described herewith came into the hands of both authors of this paper at about the same time from the same source, and were determined by each as new to science. Each being in ignorance of the fact that the other had received specimens, both proceeded to describe it. Before either description was published, however, the duplication was discovered through correspondence, and the description has been made the subject of this joint paper. The type and allotype specimens are in the United States National Museum, but paratypes are in the British Museum as stated below.

The Ischnoceran genus Mulcticola Clay and Meinertzhagen, 1938, contains five forms found on the avian family Caprimulgidae. The known species, and type host, are: M. hypoleucus (Denny), 1842, found on Caprimulgus europaeus europaeus Linnaeus; M. macrocephalus (Kellogg), 1896, found on Chordeiles minor henryi Cassin; M. nacunda nacunda Carriker, 1945, found on Podager nacunda minor Cory; M. nacunda peruviana Carriker, 1945, type host is unknown (presumed to be a member of the Caprimulgidae); and M. tenuiceps Carriker, 1945, found on Podager nacunda nacunda (Vieillot). A new species is described from material collected by one of the authors while assigmed to the United States Operations Mission to Thailand. The other new species is described from material in the British Museum (Natural History), which was graciously loaned by Dr. Theresa Clay. Appreciation is also expressed to the United Staces National Museum and to the Snow Entomological Museum of Kansas University for the loan of specimens.

A Considerable number of species of Tetrabelodont Mastodons are already known from various horizons and localities in the United States. Several of these from the Loup Fork deposits have been described by Cope, the best known being Tetrabelodon euhyphodon, T. campester, and T. productus. A fairly complete mandible recently acquired by the British Museum seems to indicate that yet another very distinct form existed contemporaneously with those just mentioned. This specimen, which forms the subject of the present note, was obtained from Mr. Sternberg, the well – known collector of fossil Vertebrates, who refers to it in his recently published work The Life of a Fossil Hunter (p. 123) under the name Trilophodon campester, Cope, from which, in spite of some similarity, I believe it to be very distinct.

Twenty-three species of Metaphycus from Africa are recognized in this paper, and of these, seventeen are described as new. The holotypes and allotypes of all new species are to be deposited in the British Museum and paratypes in the United States National Museum.

In a recent number of the Canadian Entomologist I presented a generic key to the female Pediculoididae and described a new species of Pygmephorus. I now add three more species to this genus. Types are to be deposited at the United States National Museum.

The opportunity to study some of de Koninck's (1883) type specimens from the Institut Royal de sciences Naturelle de Belgique (RMNS), specimens from the British Museum of Natural History (BMNH), and from the Museum of Comparative Zoology, Harvard University (MCZ) has provided insight into the taxonomic relationships of some polyplacophoran taxa. It is evident that errors have occurred in relating various specimens to taxa which differ significantly. Two examples of this related to a Devonian species in Germany and a Permian species in the United States National Museum of Natural History (USNM) are clarified and illustrated.

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.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
