Howell — Notes on the Distribution of Certain Mammals. 61 



Virginia : Rich Mountain, near Tazewell (4,100 feet altitude), 1. 

 Georgia: Brasstown Bald (4,300-4,750 feet), 12. 



Peromyscus polionotus subsp.* 



BEACH MOUSE. 



This handsome little mouse, previously known from Whitfield, Florida, 

 was found to be common on the white sand dunes along the outer beach 

 near Bon Secour, Alabama, where six specimens were secured. Tlieir 

 tracks were seen everywhere on the sand, where the little animals run 

 about in the scattered clumps of stunted live oak bushes. 



Sigmodon hispidus Say and Ord. 



COTTOX RAT. 



This species, while mainly confined to the Lower Austral Zone, was taken 

 on this trip in northern Georgia at the foot of the mountains ( 2,000 feet alti- 

 tude), well within the Upper Austral. It was taken also in Tennessee for 

 the first time. 



Specimens were .secured at the following localities: 



Georgia: Young Harris, 3 (common). 

 Tennessee: Soddy (Rathburn Station), 1. 

 Alabama: Huntsville, 1; Auburn, 3; Bon Secour, 4. 

 Louisiana : Lecompte, 4. 



Oryzomys palustris (Harlan). 

 RICE RAT. 



This species has been supposed to be confined mainly to the coast region 

 of the South Atlantic and (udf States. It was a great surprise, therefore, 

 wlien I trapped specimens at the foot of the Cumberland Mountains in 

 eastern Kentucky and eastern Tennes.see. The records now at hand indicate 

 tliatit pushes into the interior along the streams well within the Upper 

 Austral Zone. In view of these facts, there seems to be no further need to 

 doubt the authenticity of the specimens collected byGoss at Neosho Falls, 

 Kansas, t 



The rice rats were cauglit in small marshes in the river bottoms, and in 

 some cases in dry cultivated fields or in ditches along the railroad tracks. 

 They were particularly abundant in the marshes on the coast of Alabama. 

 Their characters are remarkably uniform over their extensive range. 



Specimens are at hand from the following localities: 

 Kentucky : Barbourville, 3. 

 Tennessee : High Cliff, Campbell County, 1; Lawrenceburg, 2; Arlington, 



Shelby County, 1. 

 Alabama: Huntsville, 4; Reform, Pickens County, 1; Bon Secour, 3; 



Montgomery, 1; Gallion, 1; Elmore, 1. 

 Mississippi : Fayette, 1.
