Faunal Areas of Maine. 



By Ora Willis KniCxHT, Bangor. 



Though the subject of "Faunal Areas of Maine" has been 

 quite fully treated in the past (Knight, Bulletin No. 3, The Univer-

 some new facts of interest have since become known. Consequently 

 the whole chapter on "Faunal Areas" was rewritten for "Birds of 

 Maine," now in press, and the map prepared to illustrate the arti- 

 cle just mentioned is given herewith, together with a brief summary 

 of the conclusions reached. The map is the chief thing to be shown 

 here, and this article is merely explanatory of certain features of it. 



At the beginning it is well to state that there are three 7ae// 

 defi^ied faunal regions in the State of Maine, the Hudsonian, Cana- 

 dian and AUeghanian. 



The Hudsonian Fauna occupies the smallest area of these three 

 in Maine. It is characterized by such plants as Diapensia lapponica. 

 Rhododendron lapponicum , Bryanthus taxifolius, Ardostaphylos alpina, 

 Saxifra^a stellaris comosa^ Arcnaria groenlandica, Lycopodiuni selago, 

 Castillcia pallida scptentrionalis^ Hierochloe alpina, Ledum palustre 

 dilatahun^ Anemone midti/ida, and Loiseliiria prociunbcns. Of bird 

 life I would regard Bicknell's Thrush as a very typical Hudsonian
