ichthyolites

Wales, and could supply ichthyolites by the ton, or a ship load of fossilised fish sufficient to supply the museums of the world.

From John O'Groats to Land's End Robert Naylor

Agassiz at once confirmed my suspicion that the ichthyolites of the Old Red

As the pterichthys and coccosteus are the characteristic ichthyolites of the Lower Old Red formation, so the cephalaspis distinguishes the middle or coronstone division of the system in England.

In the present creation fishes are either osseous or cartilaginous, that is, with bony skeletons, or with a framework of elastic, semi-transparent animal matter, like the shark; and the ichthyolites of the Old Red Sandstone unite these characteristics, resembling in some respects the osseous and in others the cartilaginous tribes.

Another of the families of the ichthyolites of the Old Red Sandstone -- the cephalaspis -- seems almost to constitute a connecting link between fishes and crustaceans.

This upper bed had also its organisms, but the circumstances were less favourable to the preservation of entire ichthyolites than those in which the organisms were wrapped up in their stony coverings.

The next step was to fix the exact place of the ichthyolites in the geological scale, and this I was enabled to do by finding a large and complete bed _in situ_.

A well-marked individual of the latter genus had, I found, been misnamed Dipterus by some geological visitor who had recently come the way, -- a mistake which, as in both ichthyolites the fins are similarly placed, occasionally occurs, but which may be easily avoided, when the specimens are in a tolerable state of preservation, by taking note of a few well-marked characteristics by which the genera are distinguished.

The description of Mr. Patrick Duff, in his "Geology of Moray," so redolent of the quiet enthusiasm of the true fossil-hunter, especially applies to the ichthyolites of this quarry, and to those of a neighboring opening in the same bed, -- the quarry of

In no deposit with which I am acquainted, however rich in remains, have all its ichthyolites been found lying together.
