NOTES ON THE MAMMALS OF MONROE AND PIKE COUNTIES, 



PENNSYLVANIA. 



BY SAMUEL N, RHOADS. 



We have much to learn respecting the man^mal fauna of the most 

 densely populated and longest settled districts of the United States. 

 To no region is this remark more applicable than the States of Penn- 

 sylvania and New Jersey. In the American Naturalist for January, 

 1893, Mr. Witmer Stone and myself recorded the capture of two 

 new species belonging to genera hitherto unknown to the fauna of 

 New Jersey, and later Mr. Stone described a Cave Rat, belonging 

 to the genus Neotoma, from South Mountain, Pennsylvania, which is 

 the first notice we have of the present existence of that genus in the 

 State. 



A recent visit to the wilder portions of northeastern Pennsylvania 

 in the interests of natural history enables me to contribute the fol- 

 lowing notes to our knowledge of the mammals of the region. One 

 week in September was spent at the farm of Mr. Chas. Yaggie, 

 (1,000 ft. alt.), on the west bank of Big Bushkill Creek, in Monroe 

 County, at a point seven miles east of Cresco, where the creek enters 

 the southwestern corner of Pike County. Another week in October 

 was occupied in the vicinity of Dingman's Ferry, Pike County, 

 and for three days I was located at Porter's Lake (1,200 feet alt.), in 

 the same county. Systematic trapping of the smaller mammalia was 

 kept up during my stay at all these localities. On the results of 

 this work and of my inquiries among the woodsmen and older 

 residents of the places visited, the following notes are based. To 

 Dr. Philip Fulmer, of Dingman's Ferry, and Mr. Harvey Eilen- 

 berger, of East Stroudsburg, the latter a veteran deer-hunter, whom 

 I had the pleasure of meeting at Porter's Lake, I am chiefly indebted 

 for outside information. The reliability of the statements of these 

 gentlemen on such subjects is unquestionable. 



The area covered by my investigations is mainly included in the 

 eastern extension of the Pocono plateau, the average elevation of 

 which, at the points visited, is from 1,000 to 1,500 feet. The greatest
