Although RISSO's collection has not been found, the current list of twelve recent brachiopod species and thirteen fossil ones identified and described by RISSO (1826) in the marine and terrestrial vicinities of Nice deserves revision by taking into account the synonyms accepted today. Adding Argyrotheca cistellula reported in 1920, the list of the extant species of brachiopods collected in the Mediterranean Sea has remained the same until 1994, date from which it increases by two species. Three of the species described by RISSO as belonging to Terebratula have been attributed as new species to him: Joania cordata, Argyrotheca cuneata, Lacazella mediterranea, all three are type species of their genus. For the fossil species, only two were identified as synonyms for Terebratula terebratula. Criticized several times, sometimes too severely, for his works on the Mollusca, to which the Brachiopoda were attributed, RISSO (1826) as an amateur naturalist completed a honourable work on this latter group, entirely comparable with those of the majority of its contemporaries and more recent authors on this group.

The genus Thecidea has been figured before it was described that gave rise to various and erroneous interpretations, in particular by English-writing authors. It must be undoubtedly attributed to DEFRANCE in CUVIER & BRONGNIART (1822). Four other descriptions derived from the original name Thecidea are nomen nullum, and are partially responsible for confusion before Thecidea was split in several new genera. Finally, only fossil species belong today to Thecidea. The history of the attribution of the author's name to Thecidea is described in detail. The type species and its synonyms, as well as the classification of the Thecidea are given. Source


Daniel OEHLERT (1849-1920) spent his entire career in Laval (Mayenne, France). His duties as a librarian of the city of Laval, then as curator of the museums of archaeology and natural history of Laval, allowed him freedom to focus on palaeontology and geology. He worked with his wife Pauline both in the field in the departments of Mayenne and Sarthe. In between field trips in the Mayenne and Sarthe, they shared the research during their long stays in Paris, working at the Sorbonne. OEHLERT's studies focused mainly on faunas of the Palaeozoic seas of Maine, Anjou and Cotentin. OEHLERT devoted himself primarily on describing crinoids, trilobites and brachiopods. In his collection, located in the Musée des Sciences (Laval, Mayenne, France), more than 20 new genera with more than 150 new invertebrate species have been described. His geological and stratigraphical work is largely original, involving almost exclusively Palaeozoic areas in the departments of Mayenne and Sarthe, and secondarily in the departments of Orne and Ille-et-Vilaine. In 1884, he took a position at the Service de la Carte géologique de France. More a hundred publications spread out from 1877 ended abruptly in 1911 with the death of his wife Pauline. A list of all his works is provided. Source


Anomia turbinata, or conical Anomia (= Novocrania turbinata), was described by POLI (1795) in the bathyal environment off the coast of the Kingdom of the Two Sicilies, Patella anomala MÜLLER, 1776 (= N. anomala) being considered a syno-nym. The history of this species, commonly considered as the Mediterranean form of N. anomala, will be described. Recently, several authors have described N. turbinata as a valid species on the basis of shell variations, as compared to N. anomala. After analysis of the taxonomic validity of these cha-racters, both species are considered as synonymous. That is supported by their occurrence in various localities, mainly in the continental shelf. Their synonymy has been corroborated by molecular analyses and is discussed with reference to the characteristics of the Mediterranean basins and their history sin-ce the Miocene. Source

The number of living brachiopod genera and species recorded to date, are 116 and 391, respectively. The phylum Brachiopoda is divided into three subphyla: Linguliformea, Craniiformea and Rhynchonelliformea. Although they were extremely common throughout the Paleozoic, today they are considered a minor phylum, and only five orders have extant representatives: Lingulida, with two families, 6 genera and 25 species; Craniida, with one family, 3 genera and 18 species; Rhynchonellida, with 6 families, 19 genera and 39 species; Thecideida, with two families, 6 genera and 22 species; and Terebratulida, with 18 families, 82 genera, and 287 species.
