PLATE XXIII.

"Great Stigmaria."

(Stigmaria ficoides, of Brongniart.
Ficoidites major, of Artis.)

The fossil here represented is a fragment of a Stigmaria having larger tubercles than the species previously described. The tubercles are oval at the base, somewhat compressed, longitudinally farrowed at the top, with a pit in the furrow.

This root is from five to six inches in diameter; the axis is seen near the compressed side, in the transverse section at the bottom of the figure.

From a sandstone quarry, near Rotherham, Yorkshire.

The specimen figured by Mr. Parkinson, ante, [Plate III.] fig. 1, appears to be the fragment of a Stigmaria of this kind in ironstone: the internal axis is seen in the transverse section pressed from its natural position to near the outer surface.
