Since the publication in 1880 of Nicholson and Etheridge's monograph of the Ordovician and Silurian fossils from Girvan, no further work has been done on the coral faunas of that region. While engaged on a revision of the rugose corals as a whole, I have studied a part of the Gray Collection in the British Museum (Nat. Hist.), of which the present article is an outcome. I am grateful to the keeper of the Department of Geology, and to Dr. H. D. Thomas for the loan of material and for the kind interest shown in my work, and to Dr. Stanley Smith for his valuable criticism and advice. This work was mainly carried out in the Sedgwick Museum, Cambridge, and I take the opportunity to express my thanks to Professor W. B. R. King and Mr. A. G. Brighton for facilities for study. Dr. H. D. Thomas and Dr. O. M. B. Bulman both kindly read the manuscript.
