454 NEW YORK STATE MUSEUM 



Joidau and Evermaun, in Bulletin 47, U. S. National Museum, 

 p. 953, state that the small dolphin is not recorded from the 

 coast of the United States; but that it inhabits the open At- 

 lantic and occurs rarely in the West Indies. De Kay, however, 

 described a dolphin, above mentioned, which appears to agree 

 with the published descriptions of the O o r y p h a e n a e q u i - 

 set is Linnaeus; and there is no reason to suppose that this 

 pelagic species does not occasionally visit our shores. It is true 

 that all the young dolphins from the New England and New 

 York coasts examined by me belong to the larger species; but 

 materials for study are scarce, and it is unwise to base a con- 

 clusion on insufficient investigation.
