' Cretaceous Polyzoa, North America,' Lonsdale ; and Messrs. 



Gabb & Horn. 



I have not been able to get access to the various works of Dr. S. G. 

 Morton on the ' Cretaceous Rocks of New Jersey,' published at dif- 

 ferent dates, from 1834 to 1842, in American scientific journals. The 

 quotations and references in the following lists are from Lonsdale's papers 

 in the ' Quart. Jour. Geol. Soc' vol. i., and from Messrs. Gabb & Horn's 

 ' Mono. Foss. Pol. of the Sec. and Tert. Formation of North America ' 

 (' Journ. Acad. Nat. Sci. Phil.' vol. v. 2nd ser. pp. 111-179, 3 plates, 1862). 

 Dr. Morton's ' Synopsis, Organic Rem. Cret. Group N. A.' was published 

 in 1834.
