Of the twenty species here listed, five are new, five are reported from 

 Eio Pirabas, State of Para, nine are found at Maria Farinha, two at 

 Montserrate, Bahia, two in the State of Sergipe, and one at Olinda, 

 Pernambuco. Two were also found at a new locality discovered by the 

 waiter at the northeast end of the island of Itamaraca. The specimen 

 from Itamaraca was found in a bed of brown sandstone. The Itamaraca 

 locality is only eleven kilometres south, and Maria Farinha is only 

 twenty-seven kilometres south of Ponta de Pedras. 



The resemblance of the fimna found in the Ponta de Pedras rocks to 

 that of the Maria Farinha beds is at once apparent, while the proximity 

 of the localities to each other bears out the theory that the same beds 

 are repeated at these two or three localities. 



At Parahyba do iS^orte, on the other hand, have been found a few 

 fossils, one of which — a species of Sphenodiscus — is so characteristic a 

 Cretaceous genus that it seems impossible to doubt the Cretaceous age 

 of the beds from which it came.^ The same beds have yielded a species 

 of Cimolichfhys, another Cretaceous genus. 



On account of his acquaintance with South American palaeontology I 

 have asked the opinion of Dr. A. E. Ortmann of Princeton regarding the 

 possible Tertiary age of some of the beds yielding the fossils described 

 by Dr. White. He writes me as follows : — 



Princeton, N. J., 27 July, 1902. 



Dear Sir, — Thanking you for your letter of May 9th I may say that I 



have used White's paper on the supposed Cretaceous in Brazil for comparison 



with my Patagonian fossils ; but, of course, I did not make a very careful 



search for allied species, since I took it for granted that we have to deal here 



with Cretaceous beds.
