Authorships within the classification.-With few exceptions, the authorship of taxa has been verified by examination of the original work. Where that was not possible, primary literature was employed. The intent was to assign authorship as accurately as possible. For example, taxa named within the volume by Lőrenthey & Beurlen (1929) are frequently cited as having been authored by both; however, Lőrenthey was the author of most of the genera and species and the authorship herein is cited as Lőrenthey in Lőrenthey & Beurlen. Determining the correct publication and date of publication, also presented challenges in several cases. The overarching principle was to assign as accurate a date of publication of taxa as possible while, at the same time, permitting recognition of the appropriate title for bibliographic purposes. For example, many of the taxa described by J. D. Dana are often attributed to his massive two-volume work, "

A phylogenetic analysis of a total of 31 species: 27 fossil species from seven families (Glypheidae, Litogastridae, Mecochiridae, Pemphicidae, Erymidae, Clytiopsidae, Chimaerastacidae), and four extant species from three families (Glypheidae, Nephropidae, Stenopodidae) is proposed. Most of the genera considered are coded exclusively based upon their type species and, as much as possible, based upon the type specimens. The cladistic analysis demonstrates that the glypheidean lobsters (infraorder Glypheidea) form a monophyletic group including two superfamilies: Glypheoidea and Pemphicoidea new status. Glypheoidea includes three families: Glypheidae, Mecochiridae and Litogastridae. Litogastridae is the sister group of the clade Glypheidae + Mecochiridae. Pemphicoidea includes a single family: Pemphicidae. A new classification of Glypheidea is proposed and currently known genera are rearranged based upon the phylogenetic analysis.

ABSTRACT. The discovery of well preserved and almost complete fossil coleoid cephalopods near Osteno in northern Italy has allowed the original study of a single specimen by Pinna (1972) to be enhanced. The unusual structure of the ten arms, showing a clear differentiation in the shape of the arm hooks (long and thin on six arms and short and stocky on the other four), is a distinctive character which is not present in any Jurassic family of coleoids known to date. We distinguish two new genera: Ostenoteuthis, with the species O. siroi sp. nov., and Uncinoteuthis, with the species U. cuvieri sp. nov. The new family Ostenoteuthidae (Order uncertain) is erected for them. The systematic position of this family within the fossil coleoids is discussed.

A rich decapod fauna from the Early Pleistocene (late Gelasian-early Calabrian) of Poggio i Sodi quarries (Siena, Tuscany, central Italy) is here reported. Integrated biostratigraphical, sedimentological and paleoecological analyses have been carried out, and some paleoenvironmental inferences are also proposed. The studied decapod community is herein assigned to the upper bathyal; several paleoenvironmental factors (cool water conditions at the sea floor, clay soft bottom, nutrients, very low environmental energy and sedimentation rate) influenced and promoted the crustacean settlement.

At Monte Magrèa series of calcarenites of Ypresian and Lutetian age is exposed. The anomuran faunas were collected from the lower strata in this succession, along the road from Monte MagrË to Monte di Malo. These levels, indurated and white in color, contain nummulitid foraminifera, nodules and fragments of coralligenous algae, and moulds of corals, molluscs and other decapod crustaceans (e.g. Cyamocarcinus angustifrons Bittner, 1883).
