252 Berry: Araucarian remains 



dwindling, and this is borne out not only by its much wider range 

 in the Tertiary but by the presence of sub-fossil remains of Agathis 

 in New Zealand, and of Araucaria in South America, in both cases 

 showing a marked shrinkage in range in very recent times. 



During the past two or three years the writer has come into 

 possession of a considerable quantity of Araucarian remains from 

 the Atlantic coastal plain. These are all of Mid-Cretaceous i _ 

 and it seems desirable to place them on record at the present time 

 since unquestionable remains of the genus Araucaria have not been 

 previously recorded from this general region and the final treatment 



of these South Atlantic Cretaceous floras will undoubtedly take a 

 long time.

 are from beds which differ in age but slightly if at all from those

 being under active investigation at the present time. 



Evidences of the abundance of the Araucarieae, using that 

 term in a somewhat extended sense, have been emphasized recently 

 through the studies of Hollick & Jeffrey * upon Staten Island 

 material ; and Seward & Ford f in their most admirable sketch of 

 the recent and past history of this group have furnished good 

 ground for the belief that the Araucarieae are the most abundant 

 type of Coniferales in the Older Mesozoic. 



Following is a brief discussion of the hitherto unknown Atlantic 

 coastal plain species : 



Araucarites Zeilleri sp. nov. 



Cone a prolate spheroid, about 9 x 7 cm. ; scales numerous, 

 long, narrow, thick ; cone-axis stout ; details of structure obscured. 



(FLATE II, FIGURE 3.) 



At the first glance this looks like a very beautifully preserved 

 Araucarian cone, but closer inspection shows that poorness of 

 preservation has^obscured nearly all of the details of structure,
