46 THE FLORA OF THE AMBOY CLAYS. 
The number of these fruit spikes found in the Amboy Clays indicates 
that a cyead grew in the region where they were deposited in greater 
abundance than would be inferred from the comparatively small number of 
eycadaceous leaves we have found; but further explorations would probably 
bring to light more of the foliage. 
These fossils form another connecting link between the flora of the 
Amboy Clays and that of the Upper Cretaceous rocks of Bohemia, so well 
illustrated by Velenovsky.

CYCADINOCARPUS CIRCULARIS Newb. n. sp. 
Pl. XLVI, figs. 1-4. 
Discoid seeds of a cycadaceous plant, from 6" to 12" in diameter, 
nearly circular in outline, though sometimes slightly heart-shaped, with 
a slight emargination at the point of attachment on one side; within the 
larger outline is a smaller circle which marks the seed itself, which is round, 
smooth, and flat, with a slight projection at the point of emargination and 
where a neck or stem penetrated the sarcocarp for attachment. , 
These fruits closely resemble some species of Cardiocarpus in the Coal 
Measures, such as C. orbicularis, C. annulatus, ete., which I have described 
in the Paleontology of Ohio, Vol. I, p. 374, Pl. XLITI, figs. 8, 10. 
We have collected perhaps fifty of these fruits, but as yet have not 
been able to connect them with any of the other plants found.

DaMMARA BOREALIS Heer. 
Pl. X, fig. 8. 
Dammara borealis Heer, Fl. Foss. Arct., Vol. VI, Abth. II, p. 54, Pl. XX XVII, fig. 5. 
In his Flora Fossilis Arctica (loe. cit.) Professor Heer describes and fig- 
ures the scales of a cone of a conifer which very much resemble those of Dam- 
mara australis, and yet there are some reasons for doubting the accuracy of his 
reference. It may also be said that the fruit scales which he calls Eucalyptus 
Geimitzi Gbid., p. 93, Pl. XLV, figs. 4-9; Pl. XLVI, fig. 12d) are without
