The unique specimen figured in Dawson's Paper ' On the Flora of the Devonian Period, etc.' (plate xvii. fig. .')2), came from this bed. I obtained here a magnificent frond of Xcurop- terispoli/morpha, Daws., showing its structure finely, and tlie different forms of the pinnules in different situations on the frond. Many of tlie species common in the underlying beds arc also to be found in this; but I am unable to give a complete list.

It will be necessary to devote a separate chapter to the interesting plant-remains of St John, Avhich present to us a picture of the vegetation of the world at a period anterior to that of tlie great coal-deposits, more perfect, perhaps, than that to be obtained in any other known locality. I shall notice here some small crustaceans and worms which lived in tlic waters into which these plants were drifted and four species of Insectn, the very oldest known to geo- logists, and which flitted through the old Devonian woods.
