Araucariopitys, a New Genus of Araucarians 1 



From a study of remains obtained from the Cretaceous Staten 

 Island deposits of the Androvette pit at Kreischerville the author 

 bases a new genus and species, which is described and illustrated 

 under the name Araucariopitys americana. The internal struc- 

 ture, which is well shown in the photomicrographic sections, 

 clearly indicates araucarian affinities, but with certain characters 

 that suggest abietinous alliances. The conclusion reached is that 

 the genus represents an extinct type, transitional between the 

 Abietinese and Araucarinese and indicating the derivation of 

 the latter from the former. 



In his concluding discussion, on p. 442, the author refers in an 

 important connection, to " the most archaic structurally known 

 abietinous type, Prepinus/' but unfortunately fails to cite any 

 authority for the name or its place of publication.

On the Structure of the Leaf in Cretaceous Pines 2 



This contribution consists of descriptions and discussions of 

 specimens of Pinaceae collected in the Cretaceous clays of Staten 

 Island at Kreischerville, together with convincing reproductions 

 of enlarged photographs, showing exterior characters, and photo- 

 micrographs of sections showing interior structure. 



A new genus, Prepinus, is proposed for a peculiar type, repre- 

 sented by short deciduous shoots, bearing numerous spirally 

 arranged leaves, enclosed in a sheath composed of nondeciduous 

 scales. A new species, P. statenensis, is described, and its struc- 

 tural characters discussed in connection with their significance
