rntcly ascertained by Dr. A. L. Hecrmann in 1853, who at that time trans* 

 mitted specimens to tlic Smithsonian Institution. The species was rcdescribed 

 by Professor Baird in 1859, from Dr. Heermann's specimen, and From a skin 

 in alcohol received from Mr. J. G. Bell, who erroneously supposed it camo 

 from Wisconsin. Soon after this date, a large suite of more than twenty 

 specimens was received at the Smith.sonian Institution from Mr. John Xuntus, 

 who collected them about San Jos^ and Capo Saint Lucas, nt the southern 

 extremity of the peninsula of Lower California. It has lieen since obtained 

 by Dr. D. C. Peters, at Fort Massachusetts, N. Mex.; by Dr. Palmer, at Camp 

 Grant, Ariz.; by Mr. F. Bischoff, in Nevada;* and by Mr. H. W. Henshaw, 

 at Cove Creek, Utah, and in Southern California. Its known range hence 

 extends from Northwestern New Mexico westward across Southern Utah and 

 Southern Nevada to California, and southward along the coast to the southern 

 point of Lower California. It probably extends in the interior far southward 

 into Western Mexico. It is, however, essentially a species of the deserts. 

 Mr. Henshawf speaks of it as living in communities, on dry sandy plains, 

 where there is very little vegetation. It thus dificrs in habits from the other 

 species of Tamiaa, whici. arc all woodland species, and in its preference for 

 open plains quite resembles the Spcrmophiles.
