A CONTRIBUTION TO THE MAMMALOGY OF NORTHERN NEW JERSEY. 



BY SAMUEL N. RHOADS. 



The following notes on New Jersey mammals are based on per- 

 sonal experience had during three collecting trips in the northern 

 portion of the State. In some cases I have added to ray own obser- 

 vations those of people living in the localities named, whose testi- 

 mony was considered thoroughly reliable. 



Trip number one was made during the last week in May, 1893, to 

 Nolan's Point, Lake Hopatcong, Morris County, collecting being 

 confined within a radius of three miles from Nolan's Point Villa, on 

 the east shore of the lake. 



The second trip included a brief stay of five days daring the last 

 week in August, 1893, at a place near Delaware Gap station in the 

 western corner of Warren County. Trapping was restricted to a line 

 of woodland and meadow connecting a lake (Sunfish Pond) 2 miles 

 distant, with the farm-house in which I lodged near Delaware Gap. 



The third and most important trip covered a period of three 

 weeks, extending from the sixth to the thirtieth days of October, 

 1896. It included three stops of one week each ; the first at Cul- 

 ver's Lake, Sussex County, the second at Unionville, Orange County, 

 New York, just across the northern boundary of Sussex County 

 near the Walkill Valley, and the third at the southern end of 

 Greenwood Lake in Passaic County. 



Considered in their faunal, geological and topographic relations, 

 there is a great similarity in all the localities named, lying as they 

 do within the Alleghenian life region, as restricted by Dr. J. A. 

 Allen, and moulded by the powerful agencies of the glacial period 

 which has left its characteristic impress upon the greater part of 

 northern New Jersey. The mountains of Warren, Sussex and Pas- 

 saic Counties are the highest on the eastern side of the Delaware 

 River, several attaining the height of nearly 1,900 feet. The Kit- 

 tatinny Range, in its continuation northward from the Water Gap, 

 runs close to two stations named in the above itinerary, viz., Dela- 

 ware Gap on the western slope and Culver's Lake (Culver's Gap) on 

 the eastern. The mountain at these places is covered mainly with
