from the southern half of the State are typical striatus. The series 

 from Somerset and Blair Counties have darker rusty crowns and 

 rumps than those from Eaglesraere and Round Island. 



27. Sciurus ludovicianus vicinus Bangs. Eastern Fox Squirrel. 



I have been unable to lay hands on any Pennsylvania specimens 

 of this squirrel except those of the light gray phase presented many 

 years ago to the Academy of Natural Sciences by Drs. Heerman and 

 Woodhouse. The exact locality of their capture is not given. 



Mr. Bangs, in his review of the eastern Squirrel, 6 quotes Dr. B. 

 H. Warren in stating that this species "is practically extinct in 

 Pennsylvania, except in the counties of Dauphin and Cumberland." 

 The following notes will be of some value in estimating the status of 

 this animal in the Commonwealth. 



Clinton County :— " Not plenty. I killed 3 last fall [1894] "— 

 Nelson. 



Cameron County : — " Very rare ; have not seen any for years " — 

 Larrabee. 



Sullivan County : — " Rare ; never seen on tops of the mountains " 

 — Bennett. 



Cumberland County : — One reported seen near Pine Grove Fur- 

 nace in 1892. Nearly exterminated — Rhoads. 



Mr. Ingersoll was unable to get any reliable notes of this species 

 in his journey through the central Alleghenies. They are practically 

 extinct in that region. 



28. Sciurus carolinensis leucotis (Gapp.). Northern Gray Squirrel. 



This animal continues to abound wherever enough timber remains 

 to supply food and shelter, even in the more densely populated 

 localities. In the northern parts of the State, especially the north- 

 western counties, the proportion of black or melanistic individuals 

 of this species sometimes equals and often exceeds the normal gray 

 form. This is reported to be the case in Clinton County by 

 Mr. Nelson, where the " blacks " sometimes outnumber the " grays " 

 two or three to one. In Sullivan County Mr. Bennett finds the 

 " blacks" numerous, but the "grays" predominate. I have never 

 seen nor heard of a black squirrel in southeastern Pennsylvania. 



29. Sciurus hudsonicus (Erxl.). Canadian Red Squirrel. 



30. Sciurus hudsonicus loquax Bangs. Carolinian Red Squirrel. 



After consulting a series of nearly 60 Chickarees from Maine, 

 Ontario, Pennsylvania and New Jersey, I am somewhat puzzled to
