are considerably macerated and decayed, like figs. 7 and 8 on the same 
plate, may perhaps have been pine cones, or they may have belonged to 
some other conifer. Future collections will doubtless solve this problem. 
Fragmentary winged seeds, apparently referable to Pinus, are represented 
by figs. 17 and 18.

Numerous and well-marked specimens of this widespread species were 
obtained by Rev. 8. Lockwood from the iron concretions in the upper 
Amboy Clays. Some of these are figured on Pl. V. Fig. 1 represents a 
branch with branchlets in which the leaves, diverging in all directions, 
have been largely broken away, but the scaled aspect of the immediate 
surface is well shown. The leaves are from 2°" to 5° in length, with a 
single keel; the scales or leaf impressions about 6™" in length, ovoid or 
rhomboidal, pointed, and keeled. Figs. 2 and 3 represent terminal branch- 
lets with long divergent leaves, while fig. 5 represents branches with short 
and closely appressed leaves, a diversity of foliage seen in many conifers. 
The large specimen figured by Heer (Flora Fossilis Arctica, Vol. VII, 
Pl. LILI, fig. 1) is much like the long-leafed branches now represented. 
The shorter form of foliage he does not seem to have met with, or has not 
identified with this plant, but our specimens represented by figs. 1-6 
are all from the same concretions and are so related that there can be no 
doubt that they belong to the same tree. Fig. 4 represents what may be a 
fruit-bearing twig, but it is too indistinct to be certainly identified as such. 
Cunninghamites elegans seems to have been extensively diffused in the 
latter half of the Cretaceous age. It was first described from Moletein in 
Moravia and from Mseno in Bohemia. Subsequently Hosius and Von der 
Marck found it in the chalk of Westphalia. Heer obtained it from the 
Atane beds of Greenland, and now we have it from the Amboy Clays of 
New Jersey. 
Locality: Near Keyport.
