DESCRIPTION OF SPECIES. 47 
doubt generically the same. They have very little resemblance to any of 
the fruits of Eucalyptus, however, which are urn-like, with a conical cover. 
On the contrary, the fruits figured by Heer under the name of Eucalyptus 
are plainly scales, and are parts of an imbricated cone. I say this with 
confidence, because it has happened that in the Amboy Clays we have 
found numbers of them sometimes associated together, oftener scattered and 
showing both faces. A peculiarity of these scales is that they are striped 
longitudinally by clefts which are filled with an amber-like substance. This 
structure is plainly seen in those figured by Professor Heer on Pl. XLV. 
Similar scales are described in an article by Mr. David White on the fossil 
plants from Gay Head. (American Journal of Science, 3d series, Vol. 
ROCKIN p98, 2b UW, digs. 9, 10.) 
The considerations which have led me to doubt whether these cone 
scales are those of Dammara are that we have found no Dammara-like 
leaves associated with them, whereas in one locality in New Jersey they 
occur in great numbers mingled with and sometimes apparently attached 
to the branchlets of an extremely delicate conifer much like Heer’s Juni- 
perus macilenta (Fl. Foss. Arct., Vol. VI, Abth. II, p. 47, Pl. XX XV, figs. 10, 
11), but the leaves are more appressed. Almost no other plant except this 
conifer is found with the cone scales, and it is difficult to avoid the conclu- 
sion that they belong together. Another reason for doubting whether these 
are the scales of a species of Dammara is that in some of them traces of 
two seeds are apparently visible, while in Dammara there is but one seed 
under each scale. 
On our plate (fig. 9) is a representation of Dammara microlepis Heer, 
taken from his work, Pl. XL, fig. 5, and also (fig. 10) one of Eucalyptus 
Geinitzi Heer, from the same volume, Pl. XLV, fig. 5, for purposes of 
comparison. 
Pinus sp.? 
Pl. IX, figs. 5-8, 17, 18. 
Not infrequently fascicles of leaves, which seem to be those of a pine, 
have been found at South Amboy and elsewhere. They are in threes, 
8™ to 10™ long, and very slender. No cones have been found with them 
which could certainly be attributed to the genus Pinus, but some which
