This species greatly resembles some of the smaller forms that have been 

 referred to Eucalyptus geinitzi, especially those with closely spaced secon- 

 daries. It is, however, quite different from the type of that species, and 

 may be distinguished by its thinner midrib, more numerous secondaries, 

 straighter marginal veins and more prominent tertiaries. It also greatly 

 resembles Eucalyptus angusta Velenovsky ' of the Cenomanian of Bohemia, 

 which species has been recorded by the writer from the upper Earitan of 

 New Jersey and the later Upper Cretaceous in North Carolina and 

 Georgia. It is possible that the two species may be confused since much 

 of the material is fragmentary. Eucalyptus wardiana is, however, more 

 elongated, straighter, with more prominent tertiary areolation, and with 

 the secondaries diverging at a wider angle. It characterizes the Magothy 

 formation from Earitan Bay in New Jersey to the Severn Eiver in Mary- 

 land, and also occurs in the Middendorf beds of South Carolina.
