The correlation value of this fauna is apparent: 

 The assemblages of species at Cape Rosier Cove 

 and Griffon Cove river have seven forms in 

 common ; the entire fauna as known is consti- 

 tuted of 50 (48) species, of which about one fifth

 half of the species are present in the Helder- 

 bergian fauna of New York with suggestions of 

 alliance in others. An Oriskany representation 

 is also present in the fauna but it is rather slight 

 and expressed by species which pass upward into 

 the Grande Greve limestone.
