Palicoidea
Palicoidea is a superfamily of crabs, comprising the two families Crossotonotidae and Palicidae. Together, they contain 13 genera, including two genera in the Palicidae known only from fossils. The two families were previously treated as two subfamilies in a Palicidae of wider circumscription. ;Family Crossotonotidae Moosa & Serène, 1981 *'' Crossotonotus'' A.

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ...

Eugène Louis Bouvier
Eugène Louis Bouvier (9 April 1856, in Saint-Laurent-en-Grandvaux – 14 January 1944, in Paris) was a French entomologist and carcinologist. Bouvier was a professor at the Muséum national d'histoire naturelle. Biography Following graduation at the normal school in Lons-le-Saunier, he taught classes in Ville-sous-la-Ferté, Clairvaux, Versailles (city), Versailles, Saint-Cloud and Villefranche-sur-Saône. From 1882 to 1887, he served as a "boursier" at the Muséum national d'histoire naturelle, where he studied with Alphonse Milne-Edwards (1835–1900) and Edmond Perrier (1844–1921). Together with Milne-Edwards, he worked on some of the crustaceans from the ''Travailleur'' and ''French aviso Talisman, Talisman'' expeditions (1880–1883). In 1887, he earned his doctorate in natural sciences with a dissertation involving Prosobranchia, prosobranch gastropods, ''Système nerveux, morphologie générale et classification des Gastéropodes prosobranches''. In 1889 he became an ass ...
