Affinities of fossils. 



In the above list most of the forms, such as the Foraminifera, the 

 majority of the Echinodermata and Gasteropoda, are lower tertiary, but 

 still there is a very distinct admixture of species 

 with cretaceous affinities, such as the Nautili, all 

 of which are connected rather with cretaceous than with tertiary types, 

 the Terebratula, which cannot be distinguished from one of the common- 

 est upper mesozoic species, and forms of Salenia, Cyclolites, 8fc. Cor-
