XXVI.—The Ordovician and Silurian Brachiopoda of the Girvan District.

Abstract

The principal descriptions and figures of the Ordovician and Silurian brachiopods of the Girvan district are found in Davidson's Monograph on the British Fossil Brachiopoda, completed about thirty years ago, and issued by the Palæontographical Society. The third volume of this work (published 1866–1870), and the Supplement to the fifth volume (published 1882–1883), dealing with species from Ordovician and Silurian beds, contain descriptions of many Girvan forms, but not apart from those occurring in other British localities. No independent and comprehensive treatise on this group as represented in the Girvan area has been published, though many short papers have dealt with a few species or portions of the fauna. Especially noteworthy are the papers and works by M'Coy and Salter, mentioned in the list at the end of this memoir.
