time I was altogether unacquainted with the distinction between Cre- 

 taceous and Tertiary fossils, and I knew next to nothing of the care and 

 discrimination required in such collecting. I now recall the fact that 

 at one of the Maria Farinha localities I sifted fossils out of piles of re- 

 siduary earth that might have represented several ditferent formations, 

 and all of these went to Dr. White simply as having come from Maria 

 Farinha. 



At a place on the northern coast of the State of Pernambuco called 

 Ponta de Pedras I found sedimentary beds containing fossils that

 examined by Dr. Ralph Arnold, who kindly made the following determi- 

 nations and correlations : —
