SILURIAN CORALS. 



675 



work on the Geology of Yorkshire. Among the 40 species of Crinoidea mentioned in that 

 work from the Mountain Limestone, there is not one of the 14 here noticed from the Silurian 

 System; and the distinction, thus evident when species are compared, would, I believe, appear 

 still more striking if the state of knowledge on the subject were sufficiently advanced to allow 

 of Mr. Miller's method of classification being entirely remodelled.'*

1 The following list of Silurian corals has been prepared chiefly from the collections made by Mr. Murchison, 

 but its compiler has had the advantage of examining valuable series of specimens belonging to the Rev. T. 

 T. Lewis of Aymestry, Mr. Benjamin Bright of Brand Lodge, Malvern, Mr. Goodhall, and Mr. Bowerbank. 



The list contains 62 species, 26 of which are supposed to be new, and the remainder have been fonnd in the 

 Eifel, Gothland, and other parts of Europe. It by no means includes all the corals of the Silurian formation 

 of England ; for in the rich slabs of Wenlock Limestone are many undetermined fossils ; and the collections, 

 which were examined while preparing the catalogue, contained numerous specimens, belonging apparently to 

 unnamed species, but the state of preservation did not permit their characters to be ascertained. 



2 These plates have been lithographed by Mr. Scharf, with great care and strict attention to fidelity of 

 character.
