respectively, but our material is too scanty for any adequate com- 
parison. Figure 6, Pl. 20, shows the twig in transverse section, 
x 60. The leaves are somewhat rhombic in transverse section and 
contain a single resin canal, as appears in the upper part of our 
figure. The specimen is too immature for identification, since the 
woody tissues are poorly developed and do not warrant the expecta- 
tion that the pitting of the tracheids of the secondary wood will be 
made out in longitudinal sections, which have not been cut on account 
of the small amount of material.

Although we have had occasion to frequently refer to the monoto- 
nously araucarineous structure of the leafy twigs and wood from the 
Kreischerville deposits, most of which present marked external 
resemblances to certain genera of the living Sequoiineae, Cupres- 
sineae and Podocarpineae, it should not be inferred that indications 
of the presence of plants with cupressinoid structure were entirely 
absent. We have found scanty remains of lignite referable to the 
genus Cupressinoxylon, but specific designation is withheld in the 
hope of being able, later on, to definitely identify them with certain 
of the leafy branches. 
Figure 2, Pl. 20, shows the structure of this material in trans- 
verse section, X 40. Resin cells are very numerous, as in the 
Cupressinoxylon type of wood. Longitudinal sections of the wood 
serve to confirm the diagnosis, for there are numerous rows of resi- 
nous parenchyma present and the pitting of the tracheids presents 
no indications of araucarineous affinities. The lateral pits of the 
ray cells are few in number and large in size, which leads.to the 
suspicion that we may have to do with a representative of the Podo- 
carpineae. This conclusion is, however, to be accepted with some 
reserve, in spite of the attempt recently made by Gothan in his 
studies on the anatomy of living and fossil gymnosperm woods? 
to separate the wood of certain of the Podocarpineae from
