Abstract
THIS very interesting fossil is derived from various localities in Scotland, all of which are believed to be Lower Devonian. It was first described in 1831 by Dr. Fleming, and since then has been noticed on several occasions, and variously regarded as the spawn of Mollusca or Crustaceans, and as of vegetable origin.
