On Cheirostrobus , a new type of fossil cone from the calciferous sandstone

The first indication of the existence of the remarkable type of fructification about to be described, was afforded by the study of a specimen in the Williamson collection, from the well-known fossiliferous deposit at Pettycur, near Burntisland, belonging to the Calciferous Sandstone Series at the base of the Carboniferous formation. This specimen is a fragment of stem, of which seven sections are preserved in the collection. Its discoverer thought it might possibly belong to theLepidostrobus found in the same bed.
