range, as far as I am able to learn are : Notropis pvocne (Cope), 

 said by Jordan 7 to range from western New York to Maryland; 

 reaches east as far as the Palisades on the Hudson. Etheo stoma 

 fta bella re Raf., also reaches to Hudson River, though Jordan 

 gives its distribution as from western New York to North 

 Carolina and westwardly. Further investigation is needed to 

 confirm my identification of Hybopsis kentuckiensis ( Raf. ) , and of 

 Moxostoma macrolepidotum Les. as correct, both of which would 

 then also range further east than is now known. The fresh 

 water species of New England 2 and of the Maritime Provinces 

 as far as the Gulf of St. Lawrence, 3 are nearly all found with 

 us, the exceptions being mostly the absence here of the more 

 northern Salmonoids. Our vicinity represents a sort of border- 

 land between the very restricted fish fauna of the New England 

 "Zoological Island," as Agassiz called it, and the far richer 

 fauna encountered in the Delaware basin immediately to the 

 west of us. + In common with the more southerly States, we 

 have a few fishes which properly belong to the eastern Caro- 

 linian fauna ; these are : 



Enneacanthus obesus Bd., which, though found in eastern 

 Massachusetts, appears to be a southern intruder and may occur 

 on Long Island, judging from the appearance there of Aphredod- 

 erus sayanns (Gill); lastly Acantharchus pomotis (Bd. ) belongs 

 to the same category. These three species are distinctively 

 lowland fishes of wide distribution along the seaboard to the 

 south. The first reaches Florida, the second Louisiana, and 

 the third Carolina. In regard to this I will refer to a conclu- 

 sion reached by Prof. Jordan 5 that these fishes represent the 

 remains of a fresh water fauna, now nearly extinguished by 

 the encroachment of the ocean upon the former shore line of 

 the continent.
