Tamias striatus (Linn.). Chipmunk. 



The Chipmunk is common in most parts of Long Island. 

 While not perfectly typical striatus it is nearer this form than 

 it is to lysteri. 



Arctomys monax (Linn.). Woodchuck. 



Common in suitable localities throughout the island, sev- 

 eral of the towns paying a bounty for their destruction, as a 

 result of which they have become greatly reduced in numbers 

 in many localities. 



Sciuropterus volans (Linn.). Flying Squirrel. 



Although seldom seen except by those familiar with its 

 haunts, it is common in suitable localities throughout the 

 island. Unlike its larger relatives — the true squirrels — it 

 seldom ventures abroad during the day, unless disturbed and 

 driven from its home, which is usually in some hole or cavity, 

 often the deserted nest of a woodpecker, in which it has 

 built its own nest of dry leaves and shreds of bark. Some- 

 times it builds a nest in the branches of a tree, preferably an 

 evergreen, again the deserted nest of a bird or a Gray Squirrel 

 may form its home, after being remodeled to suit its tastes. 

 Its family of young, two to five in number are reared in such 

 situations. I have on several occasions found evidence to 

 cause me to believe that it not infrequently destroys the eggs 

 of birds. 



Mus musculus Linn. House Mouse. 



Mus decumanus Pallas. House Rat. 



The House Mouse and the Rat are both abundant in all 

 parts of Long Island. 



Mus rattus Linn. Black Rat. 



The Black Rat has long been extinct on Long Island. 

 Many years ago some specimens were caught in a stable in 

 the city of Brooklyn.
