86 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 



1893. Neotoma pennsylvanica Stone, Proceedings Academy Natural 

 Sciences, Philada., p. 16. 



Type locality. Lewis's Cave Rocks, 6 m. from Pine Grove, Cumberland 

 Co., Pennsylvania. 



Faunal distribution. From border of lower Canadian through the transi- 

 tion zone. Also in isolated caves of the upper austral zone. Eastern Massa- 

 chusetts to Mississippi valley ; South in mountains to N. Carolina. Extremely 

 local in its habitat, being absent from extensive regions faunally and topo- 

 graphically connecting the eastern and western extremes of their distribution. 



Distribution in Pa. and N. "J. From records received, this native rat is 

 found at the present day chiefly in the mountainous parts of Pa., but it 

 occasionally descends to the cliffs and limestone caves of- the great river val- 

 leys. Most diligent inquiry and field work in Pa. east of Pine Creek and 

 Williamsport in Lycoming and Tioga Cos., and in the entire country drained 

 by the eastern and northern branches of the Susquehanna and all of the 

 Delaware River drainage area, has failed to locate this rat's existence in 

 recent times. The remains of a very closely allied fossil species (see N. 

 magister] have been found in Durham Cave, Bucks Co. and in Hartman's 

 Cave, Monroe Co. in the Delaware Valley, but no living Neotoma now appears 

 to exist in these places. West of the Susquehanna and Pine Creek, from 

 York to Fayette Cos. and from the Laurel Hill range north to eastern Mc- 

 Kean Co. and east to Tioga Co., there is a large section of middle Pa., in 

 shape like a truncated triangle based on the Maryland line, where this species 

 is quite uniformly distributed. No county included in this area is probably 

 without them, but often so sparingly distributed and in such out-of-the-way 

 places that many hunters and trappers have overlooked them entirely. 



In N. J. the only locality yet known to be inhabited by them is the Bear- 

 fort Mountain south of Greenwood Lake. They have been taken on the 

 Hudson highlands both in New York and Massachusetts, but do not appear 

 to exist in the Palisades of N. J. 



Records in Pa. Adams Co. "In rocky gorges in South Mountain near 

 Graffenburg." Strealy. Skins of two of these examined. Rhoads. 



Bedford Co. Four specimens taken by Ingersoll at Cook's Mills. Rhoads. 



Cambria Co. Three specimens taken near Walsall, in 1896, by Ingersoll. 

 Rhoads. " I have seen them in the Laurel Hill mountains near Johnstown 

 among the rocky clefts." Shields, 1900. 



Centre Co. "I have seen the species in Centre Co." Warren, Poultry 

 Book, 1897, p. 515. 



Clinton Co. Abundant in all parts of the Co. ; coming down the moun- 

 tains in winter into the barns along the Sinnemahoning Valley. Frequenting 

 rock piles in the high, flat woods and cliffs and caves on the mountain sides. 

 About fifty specimens examined from this county, from Round Island, Renovo
