on the high prairie, and from the number of runways discovered 

 may be considered common, particularly on the prairie. This 

 is a species I failed to get last summer (1898), or in fact to see 

 any signs during over four weeks collecting on the same ground."

Three specimens. 2 Dougherty, Indian Territory; i Noble, 

 Oklahoma Territory. 



" I was very agreeably surprised to find this vole in the region 

 of Dougherty, as I hardly expected to meet the subgenus here. 

 The two specimens secured were both taken the same day and 

 in the same general locality the river bottom, in which I secured 

 the cotton rats one was taken in an open runway, the other 

 from what I supposed to be an old mole burrow at the time the 

 trap was set. After this I trapped industriously for this species, 

 but failed to get any more specimens, and as the farmers there- 

 abouts did not recognize it I am forced to believe it is rare."

Ten specimens. 8 Alva, 2 Noble, Oklahoma Territory. 



"This Gopher is equally abundant on the prairie, in the sand- 

 hills and on the river bottoms about Alva; everywhere I went 

 hundreds of their hills being in sight at one time, particularly 

 near the river bluffs. I found their burrows everywhere from 

 three inches to two and one-half feet below the surface, but deep- 

 est usually on the river bottom, where they worked beneath the 

 deep, sandy, brick-like soil in the softer sand beneath. On the 

 river bluffs in the rich black soil their burrows would average 

 about ten inches under the surface. They are easy to catch in 

 properly set traps, but most of the time I was in Alva, in Jan- 

 uary and February, the earth was frozen to such a depth that it 

 was utterly impossible to dig into their runs. However, one day 

 I set a trap and took a specimen when the thermometer regis- 

 tered 10 below zero. In my opinion this would prove the species 

 to be active all winter, for at this time the earth was frozen 18-22:
