Asterophyllites than any zone of the Coal formation with which I am acquainted. The genus is represented in the Devonian of Europe, and more especially by the fine species A. coronata from Thuringia. Annularta acuminata, Dn. (Fig. 194, G). Leaves oblong, acu- minate, one-nerved, six to nine in a whorl, erect or slightly spreading. Whorls usually found disconnected. Detached whorls of this species occur, though rarely, on the surfaces of the shales of Carlton. It seems to be a plant of the same type with A. sp''nophyllo{des, Ungcr, which, according to Lesquereux, occurs in the Coal formation of Pennsylvania. Some specimens show a few whorls attached to each other by a very slender stem. Sphenophyllum antiquum, Dn. (Fig. 188, B). "Canad. Nat.," vol. vi. p. 170, fig. 7. Leaflets cuneate, one-eighth of an inch wide at the apex, and less than one-fourth of an inch long. Nerves three, bifurcating equally near the base, the divisions terminating at the apices of six obtuse, acuminate teeth. About eight leaves in a whorl. This plant was described from a few detached leaflets from the graphitic shale of St John, which preserved their form and venation in the most wonderful perfection, though they were completely.
