O.B. Davis 1935 439 Carfman, Clark Co., Idaho. June 7. About 6:00 P.M. I draw down the creek about 8 miles in search of C. artemisiae and succeeded in taking only one. Working of Thommys were plentiful in this dry area where the Artemisias was only about 12" high at the mark. I investigated several burrows and found they were less than 4" - usually about 2" beneath the surface. I found that the roots of the Artemisiae were being utilized for food. The ground squirrels were either very scarce or had gone into their burrows for the day as I saw only the one I got. There is none of that volcanic ash type of soil in this area that I have been able to locate. Everywhere it is gravel. I compared this young squirrel with others I took at Berenice and can see no appreciable difference. The measurements given by Merriam (1891:38) for U.S.N.M. no. 23489 - the type of C. artemisiae are 188-43-31. The one I took, which, from all appearances is a young of the year, is 186-43-31. Evidently Merriam's type is also young,
