material available for study is such that it can be sectioned and 
subjected to critical examination under the microscope. ‘Thus 
far the only specimens which we have so examined are those from 
Kreischerville, but it is hoped that the investigation may be con- 
tinued in the future so as to include specimens from other localities. 
Protodammara speciosa n. gen. et sp. 
Plate 1, Figs. 5-13; Plate 2, Figs. 1-5 
** Dammara microlepis Heer (?).”’ Hollick, Ann. N. Y. Acad. Sci., vol. 
11, p. 57, pl. 3, figs. 9 a, b, 1898. 
Organisms consisting of kite-shaped cone scales, from 4 to 6 mm. 
long by 4 to 6 mm. broad above, abruptly narrowed from about the 
middle to the base, rounded, incurved, and apiculate above; resin 
ducts five or more, extending down the lower surface of the limb; 
seed scars three in number, crescentically arranged above the middle 
and approximately in the broadest part of the scale, with the central 
one higher up than the laterals. 
Plate 1, Figs. 5-13, shows the scales natural size; Plate 2, Figs. 
1 a, b, ce, 2, shows four specimens with the upper surfaces exposed, 
magnified about ten diameters. Although they may be seen to 
resemble closely those of a small female cone of Dammara they 
are distinguished from the scales of that genus by the apical proc- 
ess and by the fact that they obviously bore three seeds instead 
of only one. It might indeed be inferred, from the presence of 
three apically attached ovules, that we have here to do with cone 
scales of one of the Sequoiinez, rather than with one of the Arau- 
carinee, but the internal structure shows that they are truly 
Araucarian. 
Plate 2, Fig. 3, represents a transverse section of the base of a 
scale, magnified about 40 times. A little below the middle point 
may be seen a single small fibrovascular bundle. At a higher 
plane of section this separates off a single upper bundle of inverted 
orientation and gives off a number of lateral bundles to the lower 
surface of the scale. The upper bundle supplies the seeds. In 
the higher part of the scale the inferior bundles are surrounded
