MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 53 



Records in Pa. — The following records have been secured chiefly with the 

 view of determining the numerical proportions of the normal "gray " and the 

 melanistic (abnormal?) " black " phases of color in this species, and how the 

 ratio of " blacks " increase as we approach the Canadian life zone. 



Cameron Co. — Grays and black equally divided in 1896. — Larrabee. 

 Black as numerous as gray in 1899. — Hays. 



Cambria Co. — Blacks never as plenty as grays. — Shields. 



Centre Co. — Blacks occasional in this Co. in 1899. — Rothrock. Black are 

 rare but gray abundant in 1900. — Fernald. 



Clearfield Co. — Blacks as numerous a gray in 1899. — Hays. 



Clinton Co. — Blacks as numerous as gray in 1899. — Hays. Black phase 

 rare south of Elk and CHnton Cos. — Todd. Blacks less numerous than the 

 gray in 1901. — Pfoutz. Sometimes black outnumber grays 3 to i, and some- 

 times grays seem more numerous. — Nelson. During two trips into the region 

 north of Round Island, covering about 5 weeks' hunting, I saw about half a 

 dozen squirrels of this species, one of which was intense black, another 

 smoky gray ; the rest normal gray. They are rare on the mountain tops and 

 were not abundant anywhere in the spring of 1896 and fall of 1898. —

 endeavoring to secure one for years in the South Mountain region, where 

 they are very rare, though the grays are unusually abundant. — Rhoads.
