480 PROCEEDINGS OE THE GEOIOGICAL SOCIETY. 



Lists of the MoUusca found in the Bed and Norwich Crags. 



This list is compiled like that of the Coralline Crag, with the excep- 

 tion of theNorwich-Crag species, which are largely supplemented from 

 the late Dr. Woodward's list in the Rev. J. Gunn's ' Geology of Nor- 

 folk,' and from theHsts furnished me by Mr. Eeeve and Mr. Crowfoot 

 (see pp 455 & 457). The new species introduced m the Kea Crag by 

 Mr. Jeffreys, with the assistance of Mr. Bell, are marked J in coluranl. 

 The names to which a f is prefixed denote species which Mr. Jeffreys 

 identifies with those now living, in addition to those recognized by 

 Mr Wood. A form regarded by Mr. Jeffreys as a variety ranges 

 through aU the columns in itahcs. In column III. are his critical 

 remarks, with the name first given to the species ; while other 

 names adopted by Kyst for the Belgian species are m brackets. Ihe 

 names to which a U is prefixed denote recent or living species ; but 

 these species having been originally named from fossil specimens before 

 they were known as living, the original names are retained. The 

 species supposed to be derived from the Coralline Crag have Cor. Cr. 

 marked in column III. Column VI. gives the chief localities where 

 the species occurs in the Red and Norwich Crags. Column VII. 

 shows the species which occur in the Coralline Crag, column VIII. 

 those which occur in the Belgian Crags, and column IX. those which 

 are found at Monte Mario. For columns IV., V., and IX. I am 

 indebted to Mr. Jeffi-eys. The letter d prefixed to species in column 

 II. denotes those bivalves which Mr. Bell informs me he has found 

 perfect or having the valves united in the Red Crag {ante, pp. 330 

 & 351).
