AMIA PEOM THE ISLE OP WIGHT. 



9 



According to Mr. Smith Woodward's ^ revision of the Amiidae, 

 the genus Amia is restricted to deposits of Tertiary age, although 

 closely allied forms are found in Secondary strata. Some of the 

 North American species, as we have already seen, are referable to 

 Amia, and it seems probable that others will be found to belong to 

 the same genus. In Tertiary times, therefore, Amia, which is 

 now restricted to the North American continent, must have not only 

 occupied that area, but have extended over a large part of Europe 

 as well. The recorded species may be thus tabulated : —
