Note 22 — FISHES OF THE SILURIAN ROCKS—UPPER AND LOWER. THEIR RECENT HISTORY, ORDER, AND SIZE.

“Mr. Phillips proceeded to describe some remains of a small fish, resembling the Cheiracanthus of the Old Red Sandstone, scales and spines of which he had found in a quarry at Hales End, on the western side of the Malverns. The section presented beds of the Old Red Sandstone inclined to the west; beneath these were arenaceous beds of a lighter color, forming the junction with Silurian shales; these, again, passing on to calcareous beds in the lower part of the quarry, containing the corals and shells of the Aymestry Limestone, of their agreement with which stronger evidence might be obtained elsewhere. He had found none of these scales in the junction beds or in the Upper Ludlow Shales; but about sixty or one hundred feet lower, just above the Aymestry Limestone, his attention had been attracted to discolored spots on the surface of the beds, which, upon microscopic examination, proved to be the minute scales and spines before mentioned. These remains were only apparent on the surface, whilst the ‘fish-bed’ of the Upper Ludlow rock, as it usually occurred, was an inch thick, consisting of innumerable small teeth and spines.”—Report, in “Athenæum” for 1842, of the Proceedings of the Twelfth Meeting of British Association, (Manchester.)
