CONIFERALES. 95 



Magothy formation, this species and other conifers were ex- 

 cessively abundant in this general region, and this species occurs 

 in great abundance in beds of approximately this latter age in 

 every State from New York to Alabama. 



Sequoia Rcichenbachi has a recorded range on this continent 

 from the Neocomian of Mexico to the Livingston formation of 

 Montana, and it seems to have been equally at home during the 

 greater part of the Cretaceous in Europe and the Arctic region. 

 It is possible that these remains may represent miore than a single 

 species, but of this it is impossible to judge. The Tertiary Se- 

 quoia LangsdorRi has an almost equally wide range, both ver- 

 tical and horizontal. 



In the original description, Geinitz refers this species to the 

 genus Araucarites, and several students since his day have pointed 

 out its resemblance to the Eutacta section of the genus Araur- 

 caria. If this be the true affinity, then this Cretaceous Aram- 

 caria bore Sequoia cones, for the latter have been found attached 

 to the twigs in a number of instances.
