Both are strikingly similar to the American species in every respect, 

 and likewise closely allied, in appearance at least, to the recent Araucaria 

 bidwilli of Australia. 



Kerner 1 records PacJiypliyllum (Pagiophyllum) rigidum Saporta and 

 PachypJiyllum (Pagiophyttum)araucarium Saporta from the Cenomanian 

 of Lesina, an island in the Adriatic off the coast of Dalmatia, both being 

 originally Jurassic species from the French Corallion of Verdun. Both 

 are very similar to the American species and are of about the same age. 

 The probable identity of Cenomanian and Corallian species, it seems to me, 

 is extremely doubtful, and both of Kerner's species should undoubtedly be 

 considered as new species of Aracauria, and nearly related, if not identi- 

 cal, with such Cretaceous forms as Araucaria bladenensis or Araucaria 

 toucasi. This species is represented by doubtfully determined detached 

 leaves in Maryland. It is exceedingly common in and characteristic of the 

 Black Creek formation in North Carolina. In South Carolina it is found 

 in the extension of these beds. It is present in the lower Eutaw and later 

 Cretaceous deposits in western Georgia and along the Chattahoochee 

 River. Careful search has failed to discover this species in the very fossil- 

 iferous plant beds of western Alabama, of Tuscaloosa age, but it is present 

 there is great abundance at the very base of the Eutaw deposits in Hale 

 County.

ARAUCARIA MARYLANDICA n. sp. 



Plate LIV, Fig. 2 



Description. Cone-scales narrowly elongate-obovate in outline with an 

 extended upturned distal acumen. Length of shaft of ovuliferous scale 

 about 2 cm. Maximum width, which is not far from the thickened distal 

 end, about 8 mm. to 10 mm. Minimum width, at proximal end, about 

 5 mm. Acuminate upturned tip about 6 mm. in length and 2.5 mm. 

 broad at the base. Lateral margins of scale straight nearly to the thick-
