No. 1. — Notes on the Mammals of Ontario.. 
By Gerrit S. Miller, Jr. 
The following list of the mammals of the Province of Ontario, 
Canada, is only approximately complete. It is primarily based on 
collections which I made during August, September, and October, 
1896, at three widely separated localities in the districts of Nipissing 
and Algoma. To the data thus obtained I have added the observa¬ 
tions made by Mr. Allan C. Brooks of Chilliwack, B. C., during his 
residence of ten years in the Counties of Wellington and Hamilton. 
Before he left Ontario Mr. Brooks had sent me specimens of most 
of the smaller mammals occurring in the southern part of the 
Province, and he has recently given me an annotated list of the 
species that he observed, with permission to publish any part of it 
that might be of sufficient interest. I also include the records given 
on his personal authority by Dr. Gapper in a list of the mammals of 
the region between York and Lake Simcoe, published nearly seventy 
years ago. 1 A few other published records will be mentioned in 
their proper places. While the observations now brought together 
cover the greater part of the Province, further work in the extreme 
southwestern and northwestern counties and in the region of James 
Bay is necessary before the list of mammals can be made complete.

North Bay (August 7 to September 8, 1896). — The town of 
North Bay is situated at the northeastern end of Lake Nipissing in 
the District of Nipissing. It is 240 miles north of Niagara Falls, 
325 miles south of James Bay, and 230 miles east of Sault Ste. 
Marie. Its elevation above Lake Ontario is 420 ft. and above sea 
level 655 ft.' 2 The town itself is situated on a plain only slightly 
above the level of Lake Nipissing. Toward the south and east this 
plain, broken by slight undulations only, extends as far as the eye can 
reach. North of the town, however, two abrupt ascents separated by
