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).
Grover (given name) Grover (given name) Grover is a masculine given name. Grover first became popular as a given name in the United States during the presidencies of Grover Cleveland, in part of a long-standing American trend of naming babies after presidents. Cleveland's official first name was Stephen; he was named after Stephen Grover, a former minister at the church his parents attended. However, from childhood, Cleveland's friends addressed him by his middle name instead, and so what was originally the surname Grover became a given name. According to Social Security Administration data, the name Grover increased in frequency by 850 per 100,000
