Coypu described by Juan Ignacio Molina in 1782 as "Mus coypus", a member of the mouse genus. The genus "Myocastor" was assigned in 1792 by Robert Kerr. Geoffroy Saint-Hilaire, independently of Kerr, named the species "Myopotamus coypus", and it is occasionally referred to by this name. Four subspecies are generally recognized: "M. c. bonariensis", the subspecies present in the northernmost (subtropical) part of the coypu's range, is believed to be the type of coypu most commonly introduced to other continents. Comparison of DNA and protein sequences showed that the genus "Myocastor" is the sister group to the genus "Callistomys" (painted tree-rats).
Gordon (given name) Gordon (given name) Gordon is a masculine given name in the English language. The name is derived from the Scottish surname "Gordon". It is uncertain if this surname originated from a place name in Scotland or in France. The Gordon in Berwickshire, where the family who bore the surname held lands in the 12th century, is of uncertain etymology. It is also possible that this place name was named after settlers from France, who were named after a like-named place in Normandy. The surname is thought to have been taken up as a given name in honour of the Major-General
