A MONOGEAPH 



OF THE 



BRITISH FOSSIL CORALS. 



(SECOND SERIES.) 

 Part II.— No. I. 



Corals from the Cretaceous Eormations. 

 INTRODUCTION. 



Notwithstanding several years have elapsed since MM. Milne-Edwards and Jules 

 Haime wrote their description of the Corals of the British Cretaceous series, and vast 

 additions have been lately made to the faunse of the Chalk, Upper Greensand, Gault, and 

 Lower Greensand, very few new Madreporaria have been discovered in these Upper 

 Secondary deposits. 



A few species which had been described by Mr. Lonsdale before MM. Milne-Edwards 

 and Jules Haime wrote their Monograph for the Palseontographical Society, but which 

 those authors did not consider sufficiently distinguished, appear, from the study of new 

 specimens and the examination of the original types, to be worthy of re-publication. These 

 species, with some others known in Continental Cretaceous deposits, but not hitherto 

 noticed in Great Britain, and several new species, are described and illustrated in this Part. 



Some important varieties of the species described by MM. Milne-Edwards and Jules 

 Haime and by Mr. Lonsdale have been studied and described, and some illustrations of the 

 specific forms themselves have been added in consequence of the reception of fine 

 specimens.
