Extract

Professor Agassiz, in his “Poissons Fossiles,” vol. ii. p. 78, has mentioned a species of Pygopterus as occurring in the carboniferous shales of Wardie, near Edinburgh, and which he has named P. Greenockii, in honour of Lord Greenock, the first collector of ichthyolites from that locality. He has, however, neither given a figure of this species nor any description of it, beyond saying that the known fragments consist of hardly anything but heads, with the anterior portion of the trunk, and that the scales covering this part of the body are higher than broad—a circumstance distinguishing them from the scales of all the other species of the genus.
