THE FAUNAE OF THE EASTERN PROVINCE. 35 



quite sensibly from the rest in its general faunal and 

 floral characteristics. 



II. Louisianian Fauna. Provisionally considered 

 as limited to the northward by the isotheral line of 

 77 F., and embracing all that part of the United 

 States south of such line, and east of the Great Plains, 

 excepting the Floridian Fauna. It apparently extends 

 up the coast as far as Norfolk, Virginia. 



III. Carolinian Fauna. This extends from the 

 northern boundary of the Louisianian Fauna north- 

 ward to about the isotheral line of 7i Q F. "On the 

 Atlantic coast the Fauna includes Long Island and a 

 small portion of southeastern New York, which form 

 its northern limit." 



This Fauna is of special interest for us in the pres- 

 ent connection, from the fact that its extension on the 

 eastern side, as given by Mr. Allen, requires to be 

 somewhat enlarged, in order to include a small por- 

 tion of New England. For the lower valley of the 

 Connecticut River has a Fauna, so far at least as birds 

 are concerned, which is substantially the same as that 

 of Long Island and the southeastern corner of New 

 York. Among the birds given by Mr. Allen as "spe- 

 cies limited in their northward range by the Caro- 

 linian Fauna " are the following, all of which are 

 now known to occur in southern New England : 

 Cardinalis virginiana, Euspiza americana^ Guiraca 

 coerulea, Helmintherus vermi'vorus^ Icteria vircns, 

 Wihonia mitrata, Dcndrceca ccerulea^ Pyranga czstiva, 

 Mimus -polyglottus, Thryothorus ludovicianus, Poliop- 

 tila ccerulea, Lopkophanes bicolor^ Corvus ossifragus, 

 Centurus carolinus.
