se)'icciis Cope) induces him to believe the Maiia Farinha beds of Pernambuco cno 

 probable equivalents of the Fox Hills of the United States, or to the iMjvstriclitian 

 cretaceous age. Another species from Sapucary leads him to say (p. 7) that these 

 rocks " probably belong to the cretaceous." One species from the north-eastern part 

 of the province of Bahia leads him to refer those rocks to the pliocene-pampiean.

The statement is made that the same geology (the tertiary) prevails from the 

 mouth of the Iluallagua in I'ei-u to Marajo and to Piauhy.

Though there is but little in this book which deals directly with the mesozoic 

 and tertiary geology of Brazil, Chapter YIII, upon the elevations of the eastern coast 

 of South America ; Chapter XI, on the formation of the Pampas ; Chapter XII, upon 

 the older tertiary of Patagonia and Chile, are rich in suggestions which must be kept 

 constantly before the mind in studying the cretaceous and tertiary of Brazil. Appen- 

 dices to the second part of the volume contain descriptions of secondary and tertiary 

 fossils from South America.

In this memoir Mr. Derby brings together all the observations made, up to the 

 time of publication, upon the fresh water cretaceous basin of Bahia, and the accom- 

 panying tertiary and crystalline beds. Inasmuch as Mr. Derby has done more work 

 upon this particular region than anyone else, his paper is the most comprehensive yet 

 published. Its value has now been greatly increased by the publication of Dr. 

 White's Invertebrate Paleontology of that basin. The article is in Portuguese, and 

 has never been published in any other language.
