454 REED-WRIGHT— THE VERTEBRATES OF [October i, 



kinds of localities. There is but one record of a pure albino but 

 individuals with albjnistic tendencies are not infrequent. The young 

 are born the last of March or the first of April. 



359. Sciurus cardlinensis leucotis ( Gapper) . Northern gray squirrel. 

 Fairly common throughout the basin. It is believed by many 



that this species is no longer found in the southern portion of the 

 basin. On Cornell Heights, along Fall Creek, along the Buttermilk 

 gorge, in the region of Enfield gorge and on the tops of all the hills 

 they are still common. The black phase is rarely seen although it is 

 stated that such individuals were relatively very common. Two 

 albinos have been taken at Danby. 



360. Sciurus ludovicianus ludovicianus Bangs. Northeastern fox 

 squirrel ( introduced ) . 



In the spring of 1906 six pairs were brought from another local- 

 ity and liberated in a small grove of oaks on the Cornell Campus. 

 During the first two months after their liberation several were found 

 dead and brought to the laboratory. Each showed signs of bruises 

 underneath the skin and it was thought that boys and slingshots 

 were responsible. They had been reared in captivity and were 

 extremely tame. Mr. A. A. Allen who looked into this matter 

 informs us that they were very clumsy, probably due to confinement, 

 and died from injuries received in falling from the trees. One 

 individual which fell from a considerable height was dead before 

 the spot where he had fallen was reached. During the fall of 1906 

 a few of the survivors remained in the oaks on the campus where 

 they constructed large nests of leaves but apparently none success- 

 fully passed the winter. A few migrated to the woods along Casca- 

 dilla Creek where they did survive the winter of 1907-8 and one 

 pair at least reared young during the following spring. 



361. Tamias striatus lysteri (Richardson). Northeastern chip- 

 munk. 



Abundant, especially along the ravines, stone fences and in old 

 wood lots. It is not found in the marshy areas. It goes into winter 

 quarters during the latter part of November and remains until the 

 middle of March. The latest fall record is November 26, 1906. 

 The earliest it has been seen in spring is February -26, 1905. Mr.
