N^ 





Another group of fossils which furnishes useful evidence of the 

 distinctness of the two faunas is the ^enus Inoceramus. This was 

 studied by Schliiter in Germany in 1876,' and a tabular view of this 

 zonal distribution in that country is given at the end of his monograph. 

 Recently the genus has been more thoroughly investigated, so far as 

 the British species are concerned, by Mr. H. Woods, whose excellent 

 monograph will henceforward be the chief book of reference for the 

 European species generally. 



The species which occur in France, Germany, and other countries 

 now require re-examination in the light of Mr. Woods' researches 

 and studies of the various tj-pe-specimens, but by the aid of some 

 notes on foreign forms in Mr. Woods' monograph, I have been able 

 to compile a list of those which occur in the Paris Basin.
