Wikipedia Abstract

The southern big-eared mouse (Loxodontomys micropus), also known as the southern pericote, is a species of rodent in the family Cricetidae. It is found in Argentina and Chile, and is one of only two species in its genus. The type specimen was captured by Charles Darwin in 1834 along the Santa Cruz River in Argentina, during the voyage of the HMS Beagle, and was subsequently described by George Robert Waterhouse.
