The Zariquiey Legacy Collection is part of the CBMR (ICM-CSIC). This collection was donated by Dr. Ricardo Zariquiey Alvarez (1897-1965) to the ICM-CSIC and it is mainly composed by Decapod crustaceans. Dr. Zariquiey Alvarez collaborated with the Fisheries Research Institute of Barcelona (origin of the current ICM-CSIC), and donated his collection of crustaceans with the associated library to the Institute. Dr. Zariquiey ?lvarez, like his father, Dr. Ricardo Zariquiey Cenarro (1870-1943), was a prominent pediatrician and carcinologist. His collection of crustaceans grew with their own personal contributions and with contributions from their international contacts. Dr. Zariquiey Alvarez founded the Group of Carcinologic Studies, with Dr. I. Gordon (British Museum), Dr. J. Monod and Dr. J. Forest (Museum of Natural History, Paris), and Dr. L.B. Holthuis (Museum of Leiden). The best known and studied reference of his work is "Crust?ceos Dec?podos Ib?ricos", published posthumously in 1968. His meticulousness and precision can be seen in the careful conservation of his specimens. He made important taxonomic contributions, including new types. Of the currently catalogued specimens there are types of 5 species. This collection contains mainly specimens from the Western Mediterranean (86%, especially from the Catalan area) and NE Atlantic Ocean (7%: Gulf of Cadiz, Portugal, Galicia, Cantabrian Sea, Bay of Biscay, France, Scandinavia, British Isles and North Sea). There are also important contributions from other areas of the Mediterranean (Italy) and Atlantic Ocean (Morocco, Canary Islands, Senegal, Gulf of Guinea, Angola, United States, Mexico, Venezuela, Brazil, Argentina) and the Red Sea.
