STRA.TA OF TFE HAMPSHIRE BASIX. 153 



over so large a part of North Germany overlie the Brown Coal, and 

 those of the " etage Ligurien " of C. Mayer agree so closely with the 

 forms found in the Isle-of-Wight and New-Porest beds as to put 

 their contemporaneity beyond question. The number of molluscan 

 forms obtained from this horizon at various points on the Continent 

 now greatly exceeds 1000 ; and everywhere the distinctness of this 

 fauna from that of the Bartonian is not less clearly marked than it 

 is in this country. 



Up to the present time, however, the beds which in this country 

 contain this important marine fauna have not received a distinctive 

 local appellation ; and as their position in the geological series and 

 their relations to foreign deposits are now fully established, I propose 

 to call them them the " Brockenhurst' Series," from the locality in the 

 jS'ew Forest at which they have yielded the greatest number of fossils. 



The appended list will serve to illustrate the richness and variety 

 of this second marine fauna. I have included in it a number of 

 MS. names given by the late Mr. F. Edwards ; for although the forms 

 thus designated have not been described and figured, yet they are so 

 carefully arranged and so accessible for purposes of reference in the 

 British Museum, that I think I am justified in so doing. As to the 

 question whether these forms should be regarded as species or 

 varieties, I hold it to be one of very little importance ; enough for 

 us if they can be recognized as presenting constant and distinctive 

 characters, and are found characterizing definite geological ho- 

 rizons.
