Mr. Witmer Stone has called my attention to the fact that this generic term' was published 

 by Blumenbach in the Handbuch der Naturgeschichte, GOttingen, in 1799, p. 73, four years pre- 

 vious to the edition quoted by Dr. Palmer, thus taking precedence by many years over any generic 

 term proposed for the nine-banded Armadillo. Novemcinctus is the only species included in 

 Tatu, and therefore represents the genus.
