A MONOGRAPH 



OF THE 



BRITISH FOSSIL CORALS. 



(SECOND SERIES.) 

 Part II.— No. 2. 



I. — Corals from the Upper Greensand of Haldon. 



Some time after the ' Supplement to the Monograph of the Fossil Corals of the Upper 

 Greensand ' was pubUshed several very interesting specimens of fossil Corals were sub- 

 mitted to examination from the deposit at Haldon, in Devonshire.^ It was necessary to 

 describe them, for they had not been previously noticed, and this could not be done before 

 the Corals from the Red Chalk were published. The Corals from Haldon should have 

 been described amongst those of the Upper Greensand. It is, of course, evident that the 

 list of Upper Greensand species (p. 23) is incomplete.

 of fossilization.
