New mammalian fossils from the Upper Cretaceous Upper Milk River Formation, Alberta, document the occurrence of a possibly new triconodontid species, and of an unnamed therian of metatherian–eutherian grade. The second discovered specimen of the Upper Cretaceous triconodontid Alticonodon lindoei Fox 1969 is described, and Alticondon is classified in a new subfamily. A new genus and species of spalacotheriid symmetrodont represented by lower molars at five positions and apparently not descended from the previously known spalacotheriids Spalacotherium Owen 1854 or Spalacotheroides Patterson 1955 is named and described. A lower molar is referred to the primitive therian of metatherian–eutherian grade Potamotelses aquilensis Fox 1972, The structure, size, and apparent position ([Formula: see text]) of the molar suggest relationship of Potamotelses with the Asiatic Upper Cretaceous Deltatheridiidae and the Lower Cretaceous Aegialodon Kermack, Lees, and Mussett 1965. Kielantherium Dashzeveg 1975 is a junior synonym of Aegialodon.

Abstract. Three new species and one new genus of adherent foraminiferans have been found within bivalve borings in cobbles from the Faringdon Sponge-gravel (Upper Aptian) of south-central England. The new genus and species, Lapillincola faringdonensis is a uniserial textulariine with an initial planispiral coil and a multiple aperture. Lapillincola gen. nov. is a remarkable homeomorph of Arenonina Barnard, which was originally described as an agglutinated form. Arenonina is shown here to actually be calcareous and perforate, and thus a junior synonym of Rectocibicides Cushman & Ponton. Acruliammina parvispira sp. nov. is another uniserial textulariine with an initial coil. Bullopora ramosa sp. nov. is an adherent polymorphinid with a branching, irregular series of adherent chambers. These foraminiferans may have used the bivalve borings as spatial refuges from the abrasive, high energy environment of the Sponge-gravel.

On August 11 th , 2005 I published a paper in which I described a new genus and species of sauropod dinosaur from the Upper Jurassic-Lower Cretaceous of Galve, Spain: Galveosaurus herreroi. Unfortunately, four months later, a second paper based on the same dinosaur remains was published by different authors. In this second paper, the authors gave the specimens a similar binomial name to the name I gave (with a difference of one letter, an “o”): Galvesaurus herreroi. In that paper, available on-line in pdf format from January 2006, the authors not only ignored my work, but they included a publication date: 1st July, 2005. Nevertheless, the article is included in the issue 15 th of July-December, as could be read in every page of that work. The issue was published on 18 th December 2005, but according to the ICZN code (articles 21 and 23), the date of publication of the Barco et al. (2005) paper should be considered as December 31 st , 2005 and based on the Principle of Priority, the name Galveosaurus herreroi Sánchez-Hernández, 2005 has priority and Galvesaurus herreroi Barco, Canudo, Cuenca-Bescós and Ruíz-Omeñaca, 2005 should be considered as a junior synonym of the former and therefore, an invalid name.

Horseshoeichthys armaserratus , gen. et sp. nov., (Clupeomorpha: Ellimmichthyiformes: Sorbinichthyidae) is described from the Horseshoe Canyon Formation (Maastrichtian), Albertosaurus bonebed locality, Alberta, Canada. Horseshoeichthys armaserratus is classified as an ellimmichthyiform based on the following characters: the presence of a sixth infraorbital with a sensory canal that leads to the fifth infraorbital, absence of a supraorbital bone, subrectangular predorsal scutes, parietals in contact with each other at the midline, and two supramaxillae. The specimen is classified in the Sorbinichthyidae Family as it has abdominal ribs articulating in pits on the centra, posterior spines on predorsal scutes, and absence of a median spine on predorsal scutes. A new genus and species is proposed based on the presence of (anteriorly) Y-shaped mesethmoid, supraorbital, subrectangular predorsal scutes with coarse, rounded serrae on the posterior margin and a large anterior projection, scales with serrae on the circuli, and two postcleithra. This specimen represents the first freshwater ellimmichthyiform from the Upper Cretaceous of North America and the highest paleolatitude (59°N) occurrence known for the family. Furthermore, the dentary and centra have distinctive morphologies that are matched by specimens in microvertebrate localities from three underlying formations, including the Milk River Formation (Santonian), which indicates at least a 14 million year history for this lineage.

Aldebarania arenitea (Astropectinidae; Asteroidea; Echinodermata) is described from the Rocky Point Member of the Maastrichtian (Upper Cretaceous) Peedee Formation of North Carolina. A turbulent, shallow-water environment is suggested by sedimentary features, a diverse marine fauna, and the morphology of Aldebarania. Aldebarania appears to be a partial ecological equivalent of living Astropecten and Luidia; however, phylogenetic relationships within the Astropectinidae are unstudied and the origin of similarities is unknown.

Hubbs (1938) described Typhlias pearsei, representing both a new genus and species of blind cusk-eel (Ophidiiformes: Dinematichthyidae) from freshwater caves and sinkholes of the Yucatán peninsula of Mexico. Whitley (1951:67) proposed Typhliasina as a replacement name for Typhlias, citing a list of zoological names published by Neave (1950:284), but did not mention the taxon and author to which the putative senior homonym belonged. Cohen and Nielsen (1978:60) treated Typhliasina as a junior synonym of Ogilbia Jordan & Evermann 1898 in their provisional classification of the Ophidiiformes, wherein they mentioned that Typhlias Hubbs 1938 is preoccupied by Typhlias Bryce 1910 in rotifers. Typhlias Bryce 1910 has subsequently been given as the senior homonym in three important works: the FAO species catalog of ophidiiform fishes (Nielsen & Cohen 1999:134), Checklist of the Freshwater Fishes of South and Central America (Nielsen 2003:507), and a revisionary study (Møller et al. 2004:186) in which Typhliasina is resurrected from the synonymy of Ogilbia. However, a careful reading of Neave (1950) and Bryce (1910) reveals a fact that had apparently been overlooked: Typhlias Bryce 1910 is not an available name, but a lapsus for Typhlina Ehrenberg 1831.

Two new genera and species are added to the fauna of dustywings (Coniopterygidae) preserved in Upper Cretaceous (earliest Cenomanian) amber of northern Myanmar, doubling the described diversity from this deposit.  One genus is of the subfamily Aleuropteryginae and described as Achlyoconis heptatrichia Engel, new genus and species.  This species is noteworthy for the infumate and patterned wings and unique presence of seven prominent setae positioned on thickenings occurring along the length of the forewing media.  Paranimboa litotes Engel, new genus and species, is representative of the subfamily Coniopteryginae and distinctive among Mesozoic groups for the unbranched Rs, among other traits.  In addition, a peculiar larva preserved alongside the holotype of P. litotes is described.  While having a prothoracic and head form similar to aleuropterygines as well as a labial palpus with only two palpomeres, diagnostic for Coniopterygidae, the antenna bears four articles rather than the two present in crown-group dustywings.  A revised key to the genera of Cretaceous Coniopterygidae is provided.

Tettagalma striata, new genus and species of Tettigarctidae (Hemiptera: Cicadoidea), is described from the Lower Cretaceous laminated limestones of the Crato Formation, Brazil. The new discovery represents the first certain record of this family in Brazil and confirms its presence in the Southern Hemisphere during the early Cretaceous. Architettix Hamilton, 1990, from the same formation, and all the taxa originally placed in Cicadoprosbolidae, are also included in Tettigarctidae, as the former is considered a synonym.

In handling some miscellaneous material belonging to the U. S. National Museum the writer noticed a unique specimen of a new genus and species of much interest as presenting additioiial evidence of the close relationship of those two large and important families, the Arctiidae and the Lymantriidae. A similar specimen, submitted by Dr. J. McDunnough, has served to amplify the descriptions.
