128 MICHIGAN SURVEY, 1905. 



NOTES ON THE MAMMALS OF THE PORCUPINE MOUNTAINS 

 AND ISLE ROYALE, MICHIGAN. 



CHAS. C. ADAMS. 



The specimens obtained by the expedition were largely collected and 

 prepared by Max Minor Peet assisted by N. A. Wood. Mr. Wood secured 

 the series of notes from Mr. Haring, a former fur dealer, concerning early 

 mammal records. Other members of the party, A. G. Ruthven, 0. McCreary 

 and W. A. Maclean, also contributed notes, specimens or both. 



I take pleasure in expressing our obligations to Dr. C. Hart Merriam, 

 Chief of the Biological Survey of the U. S. Department of Agriculture, for 

 kindly determining a representative series of specimens, and for the deter- 

 minations made by Mr. W. H. Osgood of the same Survey; also to Dr. Glover 

 M. Allen of the Boston Society of Natural History, for valuable suggestions 

 and for the determination of the deer and bats. The other specimens 

 > collected have been named by a careful comparison with the determined series. 



1. PORCUPINE MOUNTAINS. 



1. Odocoileus virginianus horealis (Miller) . Northern Virginia Deer. Near 

 Station II. 2, but on Section 15, an adult male was taken in the hardwood for- 

 est, August 1, and a fawn, August 14, on Section 18. V. 2. "After sundown 

 a deer came down into the marsh at the east end of Carp Lake, also a young 

 buck about a year old, and later on a doe with a small fawn" (Maclean), 

 VII. 1. "After sundown, August 3, nine deer were seen about the margins of 

 Little Carp Lake, where they were feeding on the grasses and sedges. During 

 September, 1903, deer were often surprised during the night, standing in 

 the water at the margin of Carp Lake. Trappers reported that the flies 

 were especially abundant this year" (Ruthven). During the past season 

 this habit was not observed. Trappers reported that flies were not abundant 

 owing to late spring frosts, and attributed the absence of the deer from the 

 lake, during the night, to this cause.

I. Two adult females were taken. August 21 and 28, in the cedar swamp.
