Nelson's small-eared shrew
The species was discovered by Edward William Nelson and Edward Alphonso Goldman in 1894, who collected a number of specimens from the slopes of the San Martín volcano in Veracruz, Mexico. The species was then not recorded again, and thought by many to be extinct, until being rediscovered in the same area in 2004 (as described in 2009). Its biology is essentially unknown.
