ing out that no Dammara-like 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 Bidens as to the occurrence of 
Dammara \eaves is not very conclusive, especially in view 
of the fact that Lesquereux has described the remains of cer- 
tain leaves from the Dakota Group (Dammarztes), which are 
undoubtedly related to those of the existing Dammara ro- 
busta Moore, of Australia, and various other remains both 
in this country and abroad have been referred to Dam- 
marstes. 
Furthermore, the remains from Cliffwood which Hollick 
describes (/. c.) as Araucarites ovatus are very similar to 
those of Agathis Dammara Rich. (Dammara orrentalis Lam. ; 
D. alba Rumph.) the existing Dammara of the Malayan 
Islands and Philippines. 
Fontaine (Potomac Fl. 264. pl. 133. f. 8-12) describes 
wedge-shaped scales under the name Araucarites Aguiensis 
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 
Dammara 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.
