Genus Hibolithes de Montfort, 1808 View in CoL
Hibolithes subfusiformis ( Raspail, 1829) ( Fig. 4 View FIG K-M)
MATERIAL. — Three internal moulds without written or glued indications. Original label: Nº 352/ Belemnites subfusiformis (Raspail) , Andar 17º Neocomiense, Terreno Cretaceo, Localidade Cheiron (Basses Alpes). See Figs 1D; 4N. View FIG
DESCRIPTION
Elongated guards with subfusiform outline and very acute apex. Arched dorsal and ventral sides and flanks, and subcircular cross-section. Ventral region showing a groove at the anterior part. No alveoli can be observed.
DISCUSSION
According to d’Orbigny (1840: 51), this species is recorded in the surroundings of Castellane (close to Cheiron, France), from where it was sent to him since 1825 by Émeric, an active collaborator of Raspail (1829). Combémorel & Howlett (1993) proposed to use Hibolites Mayer-Eymar, 1883 , non Hibolithes de Montfort, 1808 , as generic name, on the basis that the original drawing of the latter author does not seem to correspond to the usual interpretation of this genus. D’Orbigny (1847) included this species in the synonymy of Belemnites pistilliformis de Blainville, 1827 , but, as justified by Combémorel & Gayte (1981), they seem to belong to different genera. In fact, Vaunagites pistilliformis shows a circular posterior cross-section without groove. In the last years, the upper Valanginian-lower Barremian species H. subfusiformis , type of the genus, has been studied by some authors, such as Janssen & Fözy (2004), Fischer & Gauthier (2006), Janssen (2009) and Janssen et al. (2012).

MATERIAL. — Two internal moulds without written or glued indications. Original label: Nº 556/ Belemnitella mucronata (d’Orb) , Andar 22º Senoniense, Terreno Cretaceo, Localidade Épernay (Marne). See Figs 1D; 4R. View FIG
DESCRIPTION
Large and stout guards of subcylindrical outline and acute or obtuse apex with well-defined mucro. Subcircular crosssection, but with a ventral region slightly flattened and showing a straight fissure at its anterior part. Alveoli with large angle.
DISCUSSION
Belemnitella mucronata View in CoL was firstly reported in Epernay (Marne), France, by d’Orbigny (1850: 211). Christensen et al. (1975) redefined this species and selected a belemnite from the upper Campanian of Misburg ( Germany) as neotype, but Riegraf (2000) indicated that an original specimen of the type series was rediscovered in 1996 in the HUB. Belemnitella mucronata View in CoL is usually recorded with the belemnite species Gonioteuthis quadrata (de Blainville, 1827) , with non-circular alveolar aperture and characteristic granulate surface. In the last years, the lower Campanianlower Maastrichtian species B. mucronata View in CoL , type of the genus, has been studied by Christensen (1995, 1997, 1998a, b), Riegraf (2000), Fischer & Gauthier (2006) and Jagt (2012), among others.
CONCLUSIONS
The research in course over the palaeontological collections rescued from the remains of the devastating fire that in 1978 destroyed much of the ancient building of the current National Museum of Natural History and Science (Museu Nacional de História Natural e da Ciência) of Lisbon, Portugal, nowadays held at this institution, has allowed the rediscovery of numerous fossils, including many original labels, with high historical and scientific interest. Among them, there are several specimens of the valuable palaeontological collection that d’Orbigny, according to the wishes of Napoleon III, offered in 1855 to Pedro V as an important contribution to re-establish the good relationships and the fruitful cooperation between France and Portugal.
The Cretaceous cephalopods of this historical collection and the corresponding original labels currently recovered are presented here, being most of them figured for the first time in this work, and studied in detail from a systematic and biostratigraphic point of view. These invertebrates correspond to 11 genera and 11 species that include nautiloids: Angulithes triangularis de Montfort, 1808 ; ammonoids: Phylloceras (Hypophylloceras) tethys (d’Orbigny, 1840) , Ptychophylloceras (Semisulcatoceras) semisulcatum (d’Orbigny, 1840) , Neolissoceras grasianum (d’Orbigny, 1840) , Pleurohoplites (Pleurohoplites) renauxianus (d’Orbigny, 1840) , Acanthoceras rhotomagense ( Brongniart, 1822) , Coilopoceras requienianus (d’Orbigny, 1840) and Turrilites (Turrilites) costatus Lamarck, 1801 ; and belemnoids: Duvalia dilatata (de Blainville, 1827) , Hibolithes subfusiformis ( Raspail, 1829) and Belemnitella mucronata (von Schlotheim, 1813) . All of them come from relevant French outcrops, and they seem to have been selected by d’Orbigny with a systematically and biostratigraphically representative criterion, corresponding 9 of these 11 species to genotypes or subgenotypes.
