4. Mrs. Allen’s clay pit, South Amboy. 
Quercus, dentate leaves. Andromeda. 
(Dryophyllum). Cinnamomum Heerii Lesq. 
Sterculia, same as above. Sequoia rigida Heer. 
Myrica, or Lomatia. Sequoia Reichenbachi Heer. 
Salix protefolia. Leaves of a peculiar new kind of fern. 
In looking over this list I find that only the following plants have been 
identified in our collections: Magnolia alternans, Proteoides daphnogenoides, 
Salix proteefolia, Andromeda Parlatorii, Sequoia Reichenbachi, and Glypto- 
strobus gracillimus Lesq., the last, as shown on another page, not being a 
Glyvtostrobus. The concluding note of Mr. Lesquereux’s report is: “These 
specimens are few and poor, and therefore the determinations are not 
positively ascertained,” much of the uncertainty being due, as before men- 
tioned, to the very bad condition of the material. A number of species are 
mentioned in his list which we have never been able to recognize in any of 
our collections made from the New Jersey clays, though it is, of course, 
possible that in a flora so rich as this they may be discovered hereafter. 
To refer to certain plants in the list which we have specially sought 
without finding, we may mention Plantanus Heerii Lesq. and Sequoia condita 
Lesq., both of which are plants of the Dakota group. ‘SS. Smithsiana 
Heer” is undoubtedly intended for S. Smittiana from the Lower Cretaceous 
(Kome) beds of Greenland, which occurs in the Kootanie group, and is 
almost certainly not a member of the Amboy flora. The same may be 
said of S. subulata Heer and Magnolia Capellinii, which are likely enough to 
be found in the Amboy Clays, though we have not seen them. They are 
very widely distributed and ought to be here. Cimnamomum Heerti Lesq. 
is perhaps the species which we have called C. intermedium. In C. Heerii 
the leaf is broader, less wedge-shaped, and more prominently three-nerved. 
Sassafras is perhaps our species S. progenitor or S. acutilobum Lesq., both of 
which occur not rarely in these beds. Sequoia rigida Heer is not like any 
species we have seen, and as it occurs lower in the series it is doubtful if it 
has been found in New Jersey. Sequoia Reichenbachi is a species of great 
vertical and lateral range, occurring on Vancouver Island, in the Laramie 
group of the West, in the Cretaceous beds of Greenland, both lower and
