ened end where they curve inward, recurving to form the acuminate tip. 

 The ligule is prominent on the upper (ventral) surface of the scale to its 

 base, is somewhat thickened, and conforms in its outline to that of the 

 scale ; its distal margins are entire, and it ends medianly in a short mucro- 

 nate point. The enclosed seed is oblong-obovate with straight lateral mar- 

 gins and rounded ends. 



The present species is clearly distinct from the rather numerous Arau- 

 carian remains that have been described from the Upper Cretaceous of the 

 Atlantic Coastal Plain. It is associated in Maryland with meagerly repre- 

 sented foliage of Aracauria blandenensis Berry, an exceedingly abundant 

 and well characterized form of the Araucaria bidwilli type, which is very 

 common in the Black Creek formation of the Carolinas and the Eutaw for- 

 mation of Georgia and Alabama. In the region of its maximum abund- 

 ance from North Carolina to Alabama Araucaria bladenensis is uniformly 

 associated with the large cone-scales described as Araucaria jeffreyi Berry, 

 and it has seemed very probable that they represented the foliage and 

 ovulate scales of the same Cretaceous tree. Araucaria jeffreyi is a much 

 larger, relatively wider and otherwise very different type of sporophyll 

 from Araucaria marylandica. At the same horizon as the latter species 

 of cone-scale in the New Jersey region there occurs foliage described as 

 Araucarites ovatus Hollick, which may be related to the former. 



Among recent species there is some resemblance to Araucaria rulei, a 

 New Caledonian species of the Eutacta section of Araucaria, but on the 

 whole the present fossil form is more like the sporophylls of the Colymbea 

 section of the genus, especially those of Araucaria imbricata, the so-called 

 Chile pine.
