Nariva Series. The want of specific determinations of the 

 fossils procured by the Geological Survey renders it difficult 

 for me to establish an} 7 comparison between the fauna of the 

 deposits referred to and those of the Manzanilla and San 

 Fernando beds on the one hand. Consequently I cannot 

 be quite sure that I am correct in m} r classification of the 

 Moruga and Tamana beds. 



I propose that the names Newer Parian and Older Parian 

 applied by the Geological Survey should be dropped. The 

 Newer Parian includes the whole of the tertiary formations 

 older than the postpliocene detrital series, whilst the term 

 Older Parian was given to the lower cretaceous strata. 

 These latter may retain the local name of Pointe a Pierre 

 Beds, their geological age being probabl} r neocomian.
