Abstract
So barren of fossil remains is the Cementstone Group of the Scottish Lower Carboniferous Rocks that any addition to our knowledge of the fauna and flora of the period is especially welcome. The list of vertebrate remains is notably meagre, and such as have been found, e.g. at Abden, are generally very fragmentary.The collection to be described below contained nearly 150 specimens, and includes Plants, Lamellibranchs, Annelids, Arthropods, and Fishes: of these the Plants and Fishes are by far the most important, and constitute more than two-thirds ot the total number of specimens.
