10 PROCEEDINGS: BOSTON SOCIETY NATURAL HISTORY. 
At North Bay this species occurred on the quaking bog surround¬ 
ing a small lake and also in fields and clearings, but never in dense 
forest. Several were caught in pitfalls dug at the edge of a garden 
a few rods from the woods. At Nepigon it was common in an alder 
swamp bordering the river at a point a mile south of the settlement. 
I also'took one in the edge of the forest on the bank of a small 
stream where I expected to find Z. insignis. 
The series from North Bay and Nepigon are similar to each other 
and to specimens taken at the same season in central New York. 
A few, however, have ears slightly longer than in any others that I 
have seen. 
Zapus insignis Miller. 
The woodland jumping mouse is common at North Bay in all 
suitable places. I took one at Peninsula Harbor, but could not find 
the animal at Nepigon. 
This species was not seen by Brooks or Gapper in southern 
Ontario. 
The capture of Zapus insignis at Peninsula Harbor extends the 
known range of the species about 1,000 miles west of the type 
locality (Restigouche River, New Brunswick), and about 600 miles 
west of the most westerly points in New York and Pennsylvania 
from which it has hitherto been recorded. 
At North Bay and at Peninsula Harbor I found the animal in its 
favorite haunts — the banks of cool streams in dense forest. As 
severe frosts had occurred at Peninsula Harbor before my arrival it 
is probable that most of the jumping mice had by that time hiber¬ 
nated. In any case persistent trapping in favorable places failed to 
yield more than one specimen. At Nepigon, where Zapus hud- 
sonius was common in alder swamps and on the wooded banks of 
a small stream, Zapus insignis could not be found. 
While the specimens of Zapus insignis taken at North Bay are 
in every way typical and indistinguishable from those trapped at 
the same season in New Hampshire and New York, the one from 
Peninsula Harbor differs in many slight details from any of the 
eastern examples with which I have compared it. In color it about 
matches the brightest autumnal skins from central New York and in 
size it slightly exceeds any from that region. The ear is distinctly 
shorter than in other specimens of approximately the same size.
