cones from the Potomac formation which Fontaine refers to 

 this genus. Is about the same size and character as the cone 

 of Sequoia Reichcnbachi which Ward figures from the Black 

 Hills (Ann. Rep. U. S. Geol. Surv. 19': 674. //. 166. f. i).

While these remains are undoubtedly related to the genus 

 Araucaria, their size would seem to indicate a nearer rela- 

 tionship to the genus Ai(athis 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 Araucaria 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 IVageiopsis, so largely developed in 

 the Potomac, or various forms referred to Podozainitcs, 

 Dammara, etc., the exact affinity of which is unknown.

 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 

 cla3^s at Cliffwood as well as in the Amboy Clays and the Cre- 

 taceous of Staten Island and Block Island (Hollick). David
