A MONOGRAPH 
OF THE 
BRITISH FOSSIL CORALS. 
(SECOND SERIES.) 
Part IT.—No. 1. 
CoRALS FROM THE CretAcrous FORMATIONS. 
INTRODUCTION. 
NovrwWITHSTANDING 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 faunze 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 Palzontographical 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.
