the Amboy Clays, but they were chiefly dicotyledonous leaves, and this 
clay does not seem to be the source of the specimens mentioned by 
Conrad. The Triassic runs under the Cretaceous a short distance 
west of Washington and Middletown, and it is quite possible that the 
clays in question may be Triassic. 
Mr. I. C. Russell, in 1878, found ‘‘a considerable abundance of 
obscure vegetable remains” at an abandoned copper mine on the 
western slope of the First Newark Mountain, near Plainfield.’ 
The discovery of fossil plants in the Newark and Belleville quarries, 
as recorded in the Report of the State Geologist for 1879, has already 
been referred to (supra, p. 219). Besides the specimen of a supposed 
Lepidodendron, of which a photograph was sent to Professor Lesque- 
reux, it is added that— 
Another fragment has since been obtained from the same quarries by Dr. Skinner, 
of Belleville, and is now in our possession. It is 7 inches long, 5% inches wide, and 
13 inches thick, and is as plainly marked as the first. Other and smaller specimens 
somewhat like the above have also been found in the quarries in Newark. If these 
fossils are sufficient to determine the geological age of these beds, they put it in the 
Upper Carboniferous, at least, which is lower than has heen heretofore claimed for it. 
A larger and more complete collection of such fossils must be made if possible. 
Vegetable impressions are found in large numbers at the quarries of Mr. Smith 
Clark, of Milford, but most of them are fragmentary and indistinct. Those which 
can be seen plainly enough for identification resemble the Equisetum and some 
coniferous plants. They are evidently much newer than the fossils at Newark and 
Belleville.? 
Reference may be made to a paper by Mr. Henry Carvill Lewis, 
published in the Proceedings of the Philadelphia Academy of Sciences 
for November 24, 1879, On a New Fucoidal Plant from the Trias. 
This plant was found at Milford and is figured in this paper. The 
generic determination was made by Professor Lesquereux, who con- 
sidered it a new species Bt Paleophycus, and Mr. Lewis called it 
P. lemactformis. 
In the Report of the State Geologist of New J ersey: for 1885, page 95, 
it is stated that Prof. T. C. Porter had obtained specimens of a, conifer 
and an Equisetum in some Triassic sandstone quarries in Hunterdon 
County, and also that the Clathropteris rectiusculus Hitchcock had 
been found at a quarry near Pluckemin, in Somerset County. 
Plant remains were also seen by Mr. F. Braun in a layer from 3 to 
4 inches in thickness near the base of a bed of slate under the trap 
rock along the western bank of the Hudson River at Weehawken, 
Guttenburg, and neighboring localities in New Jersey, as noted by 
Mr. Gratacap in 1886.°
