Oct. 1899. MAMMALS FROM OKLA. AND IND. TERRS. ELLIOT. 295 



Three specimens from Dougherty, Indian Territory, i Noble, 

 Oklahoma Territory. 



" This interesting little mouse was taken along the edges of 

 the cotton fields among the dense small growth of vines, bushes, 

 etc., and as all were taken in the same character of surround- 

 ings, I am led to believe it prefers this to the .more open fields, 

 as do most of the species of this genus. One specimen was se- 

 cured one and one-half miles northeast of Dougherty. The speci- 

 men taken at Noble, O. T., in March was also secured in the 

 woodland at the edge of a cotton field. " It must be a rare species, 

 as particular pains were taken at Dougherty to secure a series, 

 but without any success beyond the three specimens." (T. S.).

Twenty-five specimens. 23 from White Horse Springs ; 2 

 canon 3 miles west of Alva, Oklahoma Territory. 



Two specimens of this new wood rat were first obtained by Mr. 

 Surber near Alva, and one of these served as the type of the sub- 

 species. Subsequently Mr. Surber procured twenty-three more 

 at White Horse Springs, west of Alva on the borders of Wood 

 and Woodward counties. The series of examples bear a 

 remarkably close resemblance and there is but little difference- 

 between the adults and young, the latter exhibiting a slightly- 

 deeper blue gray. It is a very handsome animal, the fur is 

 soft as spun silk and it can readily be distinguished from any 

 of its relatives. 



"This beautiful wood rat here called locally 'Pack Rat', was 

 first taken on February 2oth and on the following day another 

 was secured, the female. The day on which I took the first 

 specimen was perhaps the most delightful to me of any in my 

 whole field experience, though it was a bitter cold day, the 

 thermometer registering 12 below zero. I had been tramping 

 for two weeks with this rat as my object, going the rounds of 

 my traps in blizzards fully one-third of the time, but all the 

 while thinking it must be N. baileyi, and when at last I secured 

 the first specimen and saw how different it was from any wood 

 rat with which I was acquainted, my joy can better be imagined 

 than described. I first saw signs of the presence of Neotomas 

 in a small but deep canon two miles west of Alva, where they 

 had a large nest built in the hollow of a large cottonwood tree.
