GENERAL REMARKS. 
The specimen in my collection was procured near the San FrancK-o 
Mountain, New Mexico, where they were quite abundant. 
These Pouched Rats of the genus Perognathus and Geomys I procured 
whilst attached as Surgeon and Naturalist to the party under command of 
Capt. Sitgreaves, U. S. Army, exploring the Zuni, and Little and Great 
Colorado Rivers of the west. (Woodhouse.)
