two were seen almost every evening, beginning their twilight excursions about 
seven o’clock. 
38. Red Bat. Nycteris borealis borealis (Muller). — Several were seen on 
August 8, between Bovey and camp. The stomach of one examined contained 
unidentifiable insect remains, mostly Diptera. 
EXTERMINATED MAMMALS 
The following species of mammals are known to have existed in 
Itasca County within the last fifteen or twenty years, but the writer is 
unable to offer any data whatsoever that would indicate that they 
are at present to be found therein. 
1. Woodland Caribou. Rangifer caribou sylvestris (Rich.). — Formerly pres- 
ent, though it is doubtful if the type of country is such as to have attracted the 
species in any great numbers. Reported by Herrick^ from the St. Louis River 
(which is in St. Louis County) a few miles east of Itasca County. 
2. American Elk. Cervus canadensis canadensis Erxleben. — Never really com- 
mon in Itasca County, owing to the fact that it is a forested country. Reported 
by Herrick^ as common from Lake Itasca (in Clearwater County, about 35 miles 
west of Itasca County) in 1885. There are no records of either species within 
the last fifteen years. 
3. Marten. Maries americana americana (Turton). — Disappeared, appar- 
ently, soon after the caribou and elk. It is possible that an occasional marten 
may still be caught as a wanderer from another part of the coniferous area. 
4. Fisher. Maries pennanii pennanii (Erxleben). — The most recent of the 
exterminated mammals, and there is a bare possibility that it may still exist, 
though the writer can find no recent records of its presence. Like the marten, 
probably a wanderer from adjacent territory.
