bility of its range in parts of northern Pennsylvania quite as well suited to its 

 needs. 



Western FOX Squirrel. Scuirus rufiventer E. Geoffrey. 



The fox squirrel of the southwestern corner of Pa., once numerous, now 

 about extinct, probably was an intergrade, nearer typical rufiventer than 

 S. I. neglectus, the coast form. It is much more rusty than eastern Pa. speci- 

 mens, if this conjecture prove correct.* 



Canadian Flying Squirrel. Scuiropterus sabrinus macrotis Mearns. 



This southern race of the large northern flying squirrel is found in the 

 Catskill mountains, and may eventually be taken in the colder forests of the 

 northern Pa. Alleghanies. It is distinguished from the common flying 

 squirrel of the south by its size, being n inches long, 2 inches longer than 

 volans. Its upper color is similar to volans, but the under parts are not pure 

 white, as in that species, but a dirty white, with the hairs dark at base. I 

 am making strenuous efforts to secure this species in Sullivan Co. through 

 Mr. Otto Behr. 



Golden Deer Mouse. Peromyscus nuttalli (Harlan). 



This beautiful and striking species, so easily identified by its uniform 

 golden or fulvous brown color, paler beneath, has been recorded from Penn- 

 sylvania by Prof. Baird in Mammals of N. America, p. 468. One of the 

 specimens was a skull from Carlisle. Owing to the similarity of the skull of 

 this species to that of leucopus this record cannot be relied upon. Another 

 specimen, skin and skull, said by Coues to have the appearance of a leucopus 

 skinned out of alcohol, was recorded by Baird from Falls of Schuylkill, Pa. 

 I am unwilling to admit P. nuttalli to our fauna on this evidence. At the 

 same time the species may eventually be taken as a straggler in southern 

 York, Adams, Franklin or Lancaster Cos., as it ranges quite high in the 

 southern Alleghanies, as far as West Virginia or perhaps Maryland. 



Virginia Harvest Mouse. Reithrodontomys leconti impiger Bangs. 



The same remarks as to possible occurrence in Pa., just given under the 

 golden deer mouse, will almost equally apply to this tiny little dweller of the 

 fields and brush lands of the lower austral zone. It has been found in the 



* Since this writing Mr. Todd has kindly sent me a specimen of Fox squirrel taken near 

 Industry, Beaver Co., which, in comparison with eastern Pa. skins, does not indicate any 

 approach to the western race; in fact it is lighter than one Adams Co. specimen. It is a 

 female, and was collected Oct. 16, 1902. Its measurements are 555-257-70.
