SECTION AT THE FERN LEDGES. 523 appears to be limited to it. The unique specimen figured in Dawson's Paper 'On tlie Flora of the Devonian Period, ete.' (plate xvii. fig. .02), came from this bed. I obtained here a magnificent frond of Xrurop- tcris poljimorpha^ Daws., showing its .structure finely, and the diiTcrent forms of the pinimles in dilTcrent situations on the frond. Many of tlic species common in the underlying beds are also to be found in this; but I am unable to give a complete list. Total thickness of the beds embraced in this section . 444 ft. 11 ; Fauna of the Devonian Plant-beds of St John. It will be necessary to devote a separate chapter to the interesting plant-remains of St John, which present to us a picture of the vegetation of the world at a period anterior to that of the 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 the waters into which these plants were drifted and four species of Insects, the very oldest known to geo- logists, and which flitted through the old Devonian woods.
