PICKERING’S TREE TOAD. 707 
marshes thus early in the season, and he therefore thought ‘that the 
animal ~had hybernated in that situation. Whether they spend the 
winter in mud or old logs, they are found in marshes in early spring, 
where they lay their eggs. Afterwards, in the latter part of April or in 
May, they betake themselves to the woods. 
The Tree Toad is also reported to be useful as a barometer. It is said 
that, if they are placed in a tall jar, with a ladder in“it, in fair weather 
they will climb towards the top, but descend on the approach of a storm. 
How true this may be, not having tried it, I have no means of judging, 
and shall refrain from expressing any opinion on the subject.

Habitat, Maine, New Hampshire, Vermont, Massachusetts, New York, Pennsylvania,

I have not seen this species from the State, and have included it here 
solely on the extent of its extralimital range. It is found on bark of 
dead trees and on leaves, such as Indian corn and grape vines, and in 
green-houses. It has been observed in Maine to deposit its eggs in water 
in April, and at other seasons occurred in upland or damp woods among 
fallen leaves.
