Strophiops rediviva Maynard, 1913
S. rediviva new. Almost exactly like cinerea of Hog Island, differing only in being more yellowish brown externally and paler within. While these differences are remarkably constant, they are best seen in mass. 500. In field just west of St. Paul Quarry, East Nas8au. This is a singular case of recession and one which I have been enabled to trace from origin to finality and have specimens which show this astonishing transition in every detail; but I cannot here tell the story of this convincing evidence of Cyclic Recession. I perfectly agree with Mr. Harry C. Oberholser when, in speaking of similar cases among the Green Herons, he says: "This, of course, is the same problem that one meet often in wide-ranging and plastic groups, and which it seems to the writer, would be in much the best way solved by assigning a name to the isolated colony, if there can be found any character at all, however slight , to serve as a basis". Proc. U. S. Nat1. Mus., Vol. 42, p. 530. While it is highly improbable that any recessional species can ever be an exact duplicate, should such a case occur, however, we must consistently consider it equal in value to those which do exhibit differential characters. All recessional species are thus entitled to a distinctive name.
