mistake, it is the first record for Larimer County. The food of 

 the spotted ground-squirrels is the same as for the striped. Our 

 records for major are as follows: Goodpasture, Pueblo County; 

 Rocky Ford, Otero County, and Prowers, Bent County. Warren 

 also reports it from Prowers and Baca Counties.

Colorado Species of Striped Ground-Squirrels. 



Pale Striped Ground-Squirrel, Citellus tridecemlineatus pal- 

 lidus. 



Little Striped Ground-Squirrel, Citellus tridecemlineatus

The distribution of pallidus in Colorado, from our records, 

 is as follows : The plains of the eastern part of the State from lati- 

 tude 38° north to the Colorado-Wyoming line, and from the Colo- 

 rado-Kansas-Nebraska line westward to Log Cabin in Larimer 

 County, and Howard in Fremont County. Warren reports it also 

 from South Park and Leadville ; Cary from Jackson County; 

 from Wet Mountain and Huerfano Valleys, from near La Yeta 

 in the Cucharas Valley, and near Buena Vista. 



Warren reports parvus from Rio Blanca. Western Routt (now 

 Moffat) and Garfield counties, and the San Luis Valley. I have 

 taken it at Lay, Moffat County, and San Acacio, Costilla County, 

 and have seen it at Del Norte, Rio Grande County, and at La 

 Jara, Conejos County. 



Outside the State it occurs in northeastern Utah and south- 

 western Wyoming. The San Luis specimens are not typical, but, 

 in my opinion, in time the two forms will be separated. In order 

 to do this we should have hundreds of specimens of typical parvus, 

 and the same number of specimens from the San Luis Valley. As
