Distribution. — Bailey's Wood-rat has been reported from Ne- 
braska, Kansas, Missouri, Oklahoma, Texas, and Colorado. At 
present the Colorado records are very scattered, and indicate a wide 
distribution. It has been taken at Wray, Yuma County; at 
Pueblo; at Fort Lyons, Bent County; Mr. H. G. Smith reports 
rats' nests in the Arkansas bottom near Holly, Prowers County, 
which most likely belong to this species. From this data we may 
at present state that the range is that part of Colorado east of the 
mountains and north of the Arkansas River, but somewhat south 
of the river it should meet the ranges of A^. micropus and N. a. 
warreni. 
Habits. — The habits of this species are similar to those 
already described. At Wray it was found living among the 
rocks which border the bed of Olive Creek, where the col- 
lecting was done. Among these rocks were the piles of 
sticks and other treasures. Mr. Herman W. Nash states 
that at Pueblo they build nests about the small tree cactus
