A CONTRIBUTION TO THE MAMMALOGY OF CENTRAL PENNSYLVANIA. 



BY SAMUEL N. RHOADS. 



In the following annotated list are presented the results of the 

 author's study of the feral mammal fauna of central Pennsylvania 

 during the past four years. The data here submitted is of three 

 kinds: first, that recorded by the author, and based entirely on 

 his own observations in the field ; second, that obtained by employed 

 assistants in the field, and verified by specimens and notes in the 

 author's collection ; third, notes obtained from other sources, the re- 

 liability of which the author has no reason to doubt. In all cases 

 where the presence or distribution of any species rests on the third 

 class of evidence the source of such evidence is stated. 



The main sources of information are as follows, in order of sequence : 



1. A collecting trip, by the author, to Pine Grove Furnace, Cum- 

 berland County, April 11 to 15, 1893. This included a visit to the 

 limestone caves near Carlisle. 



2. A collecting trip, by the author, to Round Island, Clinton 

 County, May 25 to June 1, 1896; including a side trip taken to 

 Emporium, Cameron County. 



3. A collecting trip, by the author, to Eaglesmere, Sullivan County, 

 August 20 to 28, 1896. 



4. A collecting trip, by Mr. J. C. Ingersoll, September 24 to De- 

 cember 20, 1896; collecting being done at the following stations in 

 order of sequence: a. Tuscarora, Juniata Co.; b. Mount Union, 

 Huntingdon Co. ; c. Tyrone, Blair Co. ; d. Walsall and Kring's 

 (near Johnstown), Cambria Co.; e. Summit Mills, Somerset Co.; 

 f. Cook's Mills, Bedford Co.; g. Hopewell, Bedford Co. 



Additional records and specimens have been obtained from Messrs. 

 Seth Nelson, of Round Islaud, Clinton Co. ; M. M. Larrabee, of 

 Emporium, Cameron Co. ; A. K. Pierce, of Renovo, Clinton Co.; 

 R. W. Bennett, Eaglesmere, Sullivan Co. ; and M. W. Strealy, of 

 Chambersburg, Franklin Co. To all of these, especially Mr. Nelson, 

 whose long and intimate acquaintance as hunter and trapper of 

 the animals of Clinton, Centre, Clearfield, Cameron and Potter Coun- 

 ties is excelled by none, I gladly express my thanks for valuable aid.
