Neotoma albigula warreni, Merriam, Proc. Biol. Soc. Wash., xxi., 
pp. 143-144 (1908). 
Type locality. — Gaume's Ranch, northwest corner of Baca 
County, Colorado. 
Measurements. — Totallength, 12.75; tail vert., 5.7; hind foot, 1.5. 
Description. — (From a specimen taken at the type locality, 
May 20th) : Gray above, lightly lined with black; sides and cheeks 
rather ochraceous; flanks gray; tail sharply bicolor, black above, 
white below; feet and under parts pure clear white. 
Distributior.. — At present this species is only known from the 
type locality, and from Irwin's Ranch, in northeastern Las Animas 
County, where I took it in April, 1909, but it is probably found to 
the westward, for some distance at least, through the eastern part 
of Las Animas County. 
Habits. — This species was taken exclusively among the 
ledges of sandstone rocks bordering the gulches and shallow 
canons into which the country where it is found is cut up. 
Here were found its piles of trash about the rocks, and a 
number of specimens were easily captured. Its associates 
here were the Nebraska and Truc's Deer -mice, rock squirrels, 
and a few chipmunks. 
It did not seem to be breeding as early as N. micro pus in 
the eastern part of the county, for in the latter part of May 
the embryos found in pregnant females were small; they 
were three in number. One taken at Irwin's late in April 
contained two small embryos.
