faunas of Cleveland, as revealed by a study of the fossils 

 in the local strata, and the conclusions to be drawn therefrom 

 regarding past climatic and geographical conditions. 



The terrestrial fauna will next be dealt with, which will 

 furnish data for its history during recent geological periods. 

 Finally will come a resume of the marine, the fossil, and the 

 terrestrial faunas as a whole. 



2. — The Marine Fauna. 



The annexed table No. 1 gives so far as I have been enabled 

 to ascertain, a census of the species and genera of marine 

 animals, occurring on or off the coast as far south as Whitby. 

 The figures there shown cannot be otherwise regarded than 

 as considerably below the actual number inhabiting the 

 coast-line ; since there are many groups of marine animals 

 which have hardly received any attention from local 

 naturalists. This table does not call for any special comment 

 at our hands, but it will be noticed that it shows the fishes 

 and the mollusca are the most numerous forms of life on 

 our coast-line, so far as number of species is concerned.
