CRETACEOUS CONIFERALES 3I 
structure of the wood in longitudinal section, X 500. The pitting, 
when fully established, as it is about the middle of the figure, is 
obviously araucarineous. If we are right in correlating the speci- 
mens with structure preserved, shown in our figs. 3- 5, Pl. 20, with 
Widdringtonites Reichii, it follows that this species, in spite of its 
external resemblance to the section /Viddringtonia of the cupres- 
sineous genus Callitris, is in reality another of the many araucari- 
neous conifers which flourished during that portion of the Cretaceous 
period when the Kreischerville clays were deposited. If these con- 
clusions are justified by the facts, as they appear to be, it is a further 
proof that external appearances alone constitute a very unsafe guide 
in the matter of inferring the affinities even of late Mesozoic conifers 
with those now living. That this view of the matter is reinforced 
not only by the study of the internal structure of the twigs, but also 
from a similar study of certain cone scales associated with them, may 
be appreciated by reference to the facts in connection with remains 
of this kind elsewhere described in this Memoir.

The new genus Androvettia is not the only araucarian with verti- 
cillate leaves which has come under our notice from the Androvette 
deposits. In figs. 12-17, Pl. 8, are shown the surfaces of three 
twigs, X 10, in each case represented from the two opposite sides, 
which have the appearance and the whorled leaves characteristic of 
the genus Thuites as commonly understood, and of the specimen 
figured by Newberry from the Cretaceous of South Amboy, N. J., 
under the name Thuya cretacea (Heer) .29 
In fig. 2, Pl. 28, the base of the specimen shown in figs. 14, 15, Pl. 
8, is shown in transverse section, X 30. Two opposite leaves may 
be seen, one on the right and the other on the left of the figure. The 
plane of section in the opposite direction is not quite accurately trans-
