ALLEN : REPTILES AND AMPHIBIANS OF INTERVALE, N. H. 69 
tells me that it was much darker than specimens from farther south, 
I have examined a couple of rattlers’ skins from the Adirondacks, 
and found them to be more uniformly dark than specimens from 
Massachusetts, the white of the latter giving place to a dark 
yellow-brown. It thus seems quite probable that the northern 
rattlesnake is distinct. 
8. Ran a palustris Leconte. Marsh Frog. 
On the broad meadows of the Saco Valley, this frog is common 
along the little ponds and brooks. In Echo Lake, I found a single 
young specimen in July, which still retained its tail, but otherwise 
I was unable to find this species in the lake, liana catesbiana being 
the common frog there. During the summer, the Marsh Frog 
may frequently be found hopping about in the grass at a consider¬ 
able distance from the nearest body of water. On the 10th of Sep¬ 
tember, 1897,1 came upon a single specimen halfway up Mt. Bartlett, 
and at a long distance from the nearest water. The small mountain 
brooks for half or three quarters of a mile around were dried up, as 
was also a small swamp near by. This swamp, of a few square 
rods in extent and overgrown with bushes and sphagnum, is filled 
with water during early summer, but dries up later in the season. 
It is probable that this frog had been living in the marsh, and when 
it dried up, was forced to seek new quarters. Other than in this 
instance, I have not found the species in the woods. Hana vire- 
scens I did not find, though I looked for it carefully. It probably 
occurs in the region. 
9. Ram clamitans Latr, Green Frog. 
I7ext to 11. sylvatica , this is probably the most abundant frog. 
It occurs among the small ponds and brooks on the intervales, but 
avoids the swifter waters of the river. It works its way up along 
the small brooks which flow down into the river valley from the 
surrounding mountains, and is not uncommonly found, along these 
brooks, for some distance into the woods. Such specimens, living 
in the cold clear brooks, usually average brighter in color than 
those found in the open muddy ponds on the intervales. In the 
summer it is not i>are to find single specimens at a considerable 
distance from the nearest water. I even found one hopping along 
the sidewalk, one evening in August, at about one hundred and 
fifty yards from the brook at the edge of the intervales. This 
brook flows along the base of a steep bank which the frog must 
have climbed in the course of his wanderings. The following
