The palaeontological collections of the Muséum national d'Histoire naturelle, Paris, France, house a broad range of marine arthropods from the Solnhofen Lithographic Limestones (Late Jurassic, Germany). These arthropods include decapod crustaceans, stomatopods, supposed mysidaceans, and limulids. A commented systematic list is proposed in order to give to the specialists an instrument of comparison and reference. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.


The small Mahakamby Island (= Island of the Shrimp) is located in the Mozambique Channel (Indian Ocean) along the northwestern coast of the Mahajanga Province, (Soalala District, NW Madagascar). Miocene outcrops of Mahakamby were examined during the expeditions of two naturalists from the Muséum national d'Histoire naturelle, Paris: the first by Perrier de la Bâthie in 1915 and the second by Waterlot in 1922. Among the fossil invertebrates collected during the Waterlot's Mission, some decapod crustaceans were partially reported by Collignon & Cottreau (1927) but their specimens are nowadays. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.

In 1817, Desmarest erected Eryon cuvieri, a new crustacean from the Late Jurassic of Bavaria (southern Germany). Later, the same taxon was described as Macrourites arctiformis by von Schlotheim (1820). Subsequently, numerous authors, probably unaware of Desmarest's first paper, referred to this taxon as Eryon arctiformis (von Schlotheim, 1820). Following the Principle of Priority, the original name must be used and Macrourites arctiformis von Schlotheim, 1820 is here considered to be a more recent, subjective synonym. Moreover, two specimens of the type series of Eryon cuvieri Desmarest, 1817, from Faujas de Saint-Fond's Cabinet of Natural History, have recently been traced in the Collection de Géologie of the Muséum national d'Histoire naturelle, Paris. A lectotype is herein designated. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.

Decapod crustaceans from the Mesozoic of Madagascar have been studied by a number of authors during the last century. One of the largest sets of specimens was collected by the French General Maurice Collignon between 1930 and 1950; this was subsequently studied by Secrétan (1964) who described numerous species of macrurans, brachyurans, and axiideans. These crustaceans originate from the Upper Jurassic and the Upper Cretaceous of the Mahajanga Basin (NW Madagascar) and, especially, from the Morondava Basin (central-SW Madagascar). The purpose of the present study is twofold: to furnish an update of the stratigraphy and geology of the studied areas and, above all, to revise the Secrétan's species, employing current systematic nomenclature, supplying for each detailed geographic and stratigraphic data since such were either cursory or incomplete in previous papers. The present revision considers 13 species recorded by Secrétan as valid, namely: Enoploclytia collignoni Secrétan, 1964, Eryma granuliferum Secrétan, 1964, Pustulina spinulata (Secrétan, 1964) (all Erymidae Van Straelen, 1925); Hoploparia collignoni (Van Straelen, 1949), H. pusilla Secrétan, 1964 (both Nephropidae Dana, 1852 sensu Tshudy & Babcock 1997); Ctenocheles madagascariensis Secrétan, 1964 (Ctenochelidae Manning & Felder, 1991); Schlueteria menabensis Secrétan, 1964 (Axiidae Huxley, 1879); Linuparus bererensis Secrétan, 1964 (Palinuridae Latreille, 1802); Dromiopsis pulchella Secrétan, 1964 (Dynomenidae Ortmann, 1892); Caloxanthus simplex (Secrétan, 1964) (Etyidae Guinot & Tavares, 2001); "Xanthosia" robertsi Secrétan, 1982 (nomen novum pro Xanthosia elegans Secrétan, 1964, non Roberts, 1962), Titanocarcinus mamillatus Secrétan, 1964 (both Xanthoidea incertae sedis); and Secretanella arcuata (Secrétan, 1964) (indeterminate family). The three species described by Secrétan (1964) as belonging to the raninid genus Notopocorystes McCoy, 1849, N. bituberculatus, N. australis and N. denisae will be revised in a forthcoming paper. Our comparative studies have also revealed a number of synonymous taxa, as follows: Eryma granuliferum Secrétan, 1964 (junior synonym: E. madagascariensis Secrétan, 1964); Linuparus bererensis Secrétan, 1964 (junior synonym: L. bererensis multispinosus Secrétan, 1964); Hoploparia collignoni (Van Straelen, 1949) (junior synonym: H. intermedia Secrétan, 1964 and H. sculpta Secrétan, 1964); Schlueteria menabensis Secrétan, 1964 (junior synonym: S. tuberculosa Secrétan, 1964). Lastly, we have doubts about the systematic validity of Enoploclytia armata Secrétan, 1964, Eryma australe (Secrétan, 1964), and Coleia incerta Secrétan, 1964, because of the absence of main diagnostic features, useful for their systematic ascription. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.

Erymid lobsters (Decapoda, Erymidae) are a relatively abundant family of decapod crustaceans with a presumed conservative morphology. For these reasons, numerous species of erymids have been synonymized with others by early efforts to review the family. Eryma greppini Oppel, 1861, is one of these. A well-preserved specimen of erymid lobster assigned to this species has recently been traced in the palaeontological collections from the Université Claude Bernard Lyon 1 (France). Study of this specimen and examination of the type material of Eryma greppini, Eryma affinis Ferry, 1865, and Eryma bedeltum (Quenstedt, 1857) lead us to consider Eryma greppini to be a valid species, characterized by a peculiar pair of dorsal domes. A lectotype is herein designated for Eryma greppini. This study is a first step toward the necessary revision of erymid lobsters and proves the importance of taxonomic studies based on type material. © 2014 E.
