cones from the Potomac formation which Fontaine refers to 
this genus. Is about the same size and character as the cone 
of Seguota Reichenbachi which Ward figures from the Black 
Hills (Ann. Rep. U.S. Geol. Surv. 19’: 674. pl. 166. f. 7).

While these remains are undoubtedly related to the genus 
Araucaria, their size would seem to indicate a nearer rela- 
tionship to the genus Agathis Salisb. (Dammara Lam.). The 
only other American post-Jurassic references to Araucarites 
are two species of cones from the Potomac which Fontaine 
so identifies. The genus Araucarta of Jussieu occurs abun- 
dantly from the Jurassic upward; Fontaine describes three 
species from the Potomac formation and Lesquereux a doubt- 
ful species from the Dakota Group. Wood of this type has 
been identified by Knowlton from the Triassic (?) and the 
Lower Cretaceous of South Dakota. All of the foregoing 
have very small, more or less imbricated and compressed 
leaves, while this species of Hollick’s is much larger and 
suggests similarity with Vagezopsis, so largely developed in 
the Potomac, or various forms referred to Podozamtites, 
Dammara, etc., the exact affinity of which is unknown. 
Dammara Lam. Encycl. 2: 259. 1786. 
The living species are included in the genus Agathis 
Salisb. and are four in number, ranging from the Malayan 
Islands and Philippines to Australia and New Zealand.

These problematical remains are very abundant in the 
clays at Cliffwood as well as in the Amboy Clays and the Cre- 
taceous of Staten Island and Block Island (Hollick). David
