ing out that no Daffimara-Mke foliage has been found asso- 

 ciated with them and that in the very abundant Amboy Clay 

 specimens the scales seem to be associated with an extremely 

 delicate juniper-like conifer ; this association has never been 

 confirmed, however. He also finds some indications of two 

 seeds in his specimens, the living Dammara scales being one- 

 seeded. Merely negative evidence as to the occurrence of 

 Dammara leaves is not very conclusive, especially in view 

 of the fact that Lesquereux has described the remains of cer- 

 tain leaves from the Dakota Group {^Dammar ites)^ which are 

 undoubtedly related to those of the existing Dammara ro- 

 btista Moore, of Australia, and various other remains both 

 in this country and abroad have been referred to Dam- 

 mar it es. 



Furthermore, the remains from Cliffwood which Hollick 

 describes (/. c.) as Araucarites ovatus are very similar to 

 those of Agathis Dammara Rich. {^Dammara orientalisYi-d.va. ; 

 D. alba Rumph.) the existing Dammara of the Malayan 

 Islands and Philippines. 



Fontaine (Potomac Fl. 264. fl. ijj. f. 8-12) describes 

 wedge-shaped scales under the name Araucarites Aquiensis 

 from the Potomac Formation near Brooke, Va., where they 

 are common and always found detached and unassociated 

 with other remains. While their resemblance to those of 

 Dajnmara may be considered somewhat far-fetched, their 

 similar mode of occurrence is suggestive. They are as a 

 rule larger than Dammara^ but vary considerably in size 

 and shape and have a transverse furrow on their upper mar- 

 gin.

 Pending the discovery of fruit the identification of these 

 remains with those of the existing genus Cunninghamia is 

 not beyond question. Cunninghamia R. Br., with a single 

 species, is at the present day an endemic genus of the China- 

 Japan region.
