MILLER: MAMMALS OF ONTARIO. 
43 
A very large adult male taken at Peninsula Harbor on October 8, 
1896, measures: total length, 610; tail vertebrae, 200; hind foot, 
65; ear from meatus, 25; greatest length of skull, 70. This speci¬ 
men probably represents about the maximum size attained by the 
typical subspecies. 
I caught this mink in a steel trap baited with mice and set at the 
corner of a boat'house on the shore of the harbor. His track as he 
approached the trap could be traced for fully an eighth of a mile 
along the sandy beach. He had followed the water’s edge closely 
most of the way but occasionally had made short excursions up the 
beach in search of prey. On one of these side expeditions he had 
captured a shrew (Sorex personatus) which had also left its track in 
the sand. The tracks of the two animals showed that the shrew 
was not killed until he had led his enemy a sharply zigzag chase. 
The mink left the tail and hind quarters of the shrew lying on the 
sand, and continued his way directly to my trap.
