3. Cervus americanus (Erxl.). Wapiti. 



The " Elk " was probably never as numerous in this region as in 

 the central Alleghany Mountains, those individuals taken in former 

 days being considered by the natives as stragglers from the main 

 body. The last capture in Pike County was probably not later than 

 1840 or 1845. 



Remains of the Bison and Caribou found in Hartman's Cave near 

 Stroudsburg, have been described and figured by Dr. Jos. Leidy in 

 the Penua. Geological Report for 1887. 



It is very improbable that either species co-existed in this part of 

 Pennsylvania, with Man. 



4. Sciurus carolinensis pennsylvanicus (Ord). Northern Gray Squirrel. 

 Very few were seen. They are said to be abuudant in certain 



localities of exceptional food supply. The hunters frequently shoot 

 the melanistic form, which is the original variety on which George 

 Ord based his specific name for the "Small Black Squirrel" of 

 Guthrie's Geography, in 1815. 



5. Sciurus hudsonicus (Erxleben). Eed Squirrel, Chickaree. 



Abundant as the sparsely wooded character of the country will 

 permit. 



6. Sciuropterus volans (L.) Jordan^ Flying Squirrel. 



No specimens of this animal were seen. They are reported as 

 numerous, and more frequently found in nests built among the 

 branches of a pine than in hollow trees. It is very probable that 

 this species on the Pocono mountain is nearer to the typical Virginian 

 form than to sabrimis of the Canadian fauna, as in the case of 

 Tamias striatus and its subspecies T. s. lysteri. 



7. Tamias striatus (L.). Chipmunk. 



In the more mountainous districts the chipmunk is by far the most 

 ubiquitous mammal of its class, the more favorable situations being 

 so thickly tenanted by them as to suggest the Spermophile colonies of 

 the West. They showed no disposition to hibernate up to the last 

 day of my stay (October 14th), though the nights were often frosty. 



Pocono chipmunks are referable to typical striatus rather than to 

 the Canadian variety, T. s. lysteri, which is found in the northwestern 

 parts of Pennsylvania.
