FAUNAL POSITION.

Warblers; White- winged and Red Crossbills, White- throated Sparrow, 
junco, Rusty Blackbird, Raven, Canada Jay, Olive sided Flycatcher, 
Black-backed and Banded-backed Three-toecl Woodpeckers, Spruce 
Grouse, Goshawk, and Golden-eyed Duck. In addition to the above 
it is not improbable that the Hudsonian Tit and one (or both) of the 
Kinnlets will be found nesting here. 
Mention of the characteristic Reptiles, Batrachians, and Fishes is 
deferred, and will be made in the chapters pertaining to these groups. 
Following is a list of “ Subarctic ” species of Lepidoptera collected 
in the immediate vicinity of Beaver Lake (also called “ Fenton’s,’’ and 
“ Number 4”) in Lewis County, by Mr. Hill, and identified by Prof. 
J. A. Lintner, late State Entomologist : Agrotis Chard inyi, A. con- 
flua, A. astricta, Plusia biniacalata , P. n-aureum , Phamnonoma brnn- 
ncata, Mclanippc hastata , M. fluduata , Coremia ferrugaria , Cidaria 
Pa char data, C. albolineata, C. cunigerata , C. hers Hi at a, C. truncata , 
Spargamia magnoliata , Oporabia cambricaria , and Larentia ccesiata. 
These were all found in a single locality, and therefore probably con- 
stitute but a small proportion of the northern Lepidoptera that occur 
in the Adirondacks. 
Floral limitations are by no means so clearly defined as the boun- 
daries of Faunal areas, and for the reason that plants are much more 
easily than animals affected by minor physiographical conditions. 
They are more susceptible to the influences ol local topographical and 
climatic conditions, such as altitude, humidity, etc., and are also 
affected by the nature of the soil, and by association with one another. 
This is seen in the influence which certain kinds of forests exert in 
determining the character of the more humble plants that grow in 
their shade. For example, it is well known that the destruction of 
an evergreen coniferous forest is commonly followed, in the course of 
nature, by a growth of hard timber- -maple, beech, and birch (all decid- 
uous trees) usually predominating. 'Coincident with this change of 
forest is an equally radical change in the kinds of small plants that 
spring up underneath.
