Near Greeley Loring found P. Jiavus abundant over a sandy strip of country, living among chunps of yucca and pricldy pear. Streator collected a series of specimens in sunflower patches on waste land. Fig. 23.—Distribution in Colorado of Baird pocket mouse (Perognathus flavus). near Loveland in October, baiting his traps almost exclusively with sunflower seeds, which appeared to be the chief food of these mice at the time. Prof. Lantz found a large store of sunflow^er seeds in a burrow which he dug out in southeastern Otero County in April, 1910. He observes that the tail of this species is to some extent prehensile. In the case of several w^hich he carried alive in his hand, the tail at times clasped a finger. In Shell Kock Can3^on, northwestern Baca County, I usually found the burrows beneath tree cactus {Opuntia arhorescens) in the sandy bed of the canyon or on the adjoining benches. There are specimens from Burlington, and Streator reported this species at Olney and Flagler. I saw numerous signs of small pocket.
