88 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 



Sullivan, Lycoming, Wyoming, Lackawanna, Wayne, Luzerne, Carbon, 

 Northampton and Lehigh Cos. Numerous competent observers from the 

 large area of country included by these counties agree that this rat is un- 

 known in that region. The probability of the discovery of this rat in the 

 Blue Ridge of Berks and Schuylkill Cos. is indicated by the following quota- 

 tion from " Pennants' History of Quadrupeds," 1781, page 441, under caption 

 of "American Rat." "Mr. Bartram [in Kalm's Trav., 1771, pp. 47, 48] 

 mentions the rat, but does not determine the species, which lives among the 

 stones and caverns in the Blue Mountains, far from mankind ; comes out at 

 night and makes a terrible noise, but in very severe weather keeps silent 

 within its holes." 



Tioga Co. " Have heard of them in Tioga Co." Cleveland, 1900. 



Westmoreland Co. I secured a specimen from Laurel Hill, about three 

 miles above Laughlintown on the road to Jenner, in 1 898. Rhoads. 



York Co. Near York Furnace station, in the Wind Caves along the Sus- 

 quehanna River, J. S. Witmer saw one alive in June, 1897. His unsolicited 

 testimony as to the peculiar characters of this animal, contrasted with those 

 of other rats, makes this identification reliable. Stone. Prof. Justin Roddy 

 of Millersville writes me he has specimens from the Wind Caves. Rhoads, 

 1903. 



Records in N. J. Passaic Co. " Soon after my arrival at Greenwood 

 Lake, I was told by a local sportsman that he had once caught a ' wood-rat ' 

 on the nearby mountain in a dead-fall set for skunks. The summits of Green- 

 wood [Bearfort] mountain at the south end of the lake are made up exclu- 

 sively of great masses of glaciated conglomerate and shale. Chestnut and 

 scrub oaks and dwarfed pines and hemlocks sparingly cover the nakedness of 

 this desolate but picturesque locality. . . . After nearly two days of climbing 

 here, I stumbled upon an escarpment from which the rock masses had so 

 fallen into the gorge as to form a roof. Beneath this, unmistakable signs of 

 the rats were found, and in the two following days, three specimens were 

 trapped." Rhoads, Proc. Acad. N. Sci., Phila., 1897, p. 28. 



Warren Co. " I was informed by a hunter at Delaware Gap that he 

 knew of such an animal on the Kittatinny mountain in Warren Co. This 

 statement I was unable to verify, owing to my short stay at that place." 

 Rhoads, Proc. Acad. N. Sci., Phila., 1897, p. 28. 



Habits, etc. The following remarks relate to a visit made in the spring of 

 1893 to the Lewis' Cave rocks from which Mr. J. G. Dillin secured the types 

 of Mr. Witmer Stone's Neotoma pennsylvanica : " The rocks lie at the top of 

 the mountain and form the culminating point of a rocky outcrop topping the 

 ridge for a mile or more in this locality, and which at intervals assumes a 

 very rugged and castellated outline. The cave rats live in the more inac- 

 cessible fissures and clefts of these rocks, selecting for their dormitories those
