manuscript and plates of the ‘‘ Flora of the Amboy Clays,’’ soon 
to be published as a monograph of the United States Geological 
Survey. Iam also indebted to Dr. N. L. Britton for assistance 
in comparing the fossils with living species. Credit for 
collecting a number of valuable specimens is due to Mr. Wm. T. 
Davis of the Natural Science Association of Staten Island, and 
to Mr. Heinrich Ries of the New York State Museum. 
I have thought it best, in view of the unsatisfactory character 
of much of the material, to designate many of the species 
provisionally, trusting that future investigation may bring to 
light sufficient and better material for more exact determinations. 
The clays are being constantly excavated and plant bearing 
layers may be exposed at any time which may yield valuable 
results, so that this paper is to be considered as largely 
preliminary and the conclusions as subject to modification, so 
far as some of the identifications of species are concerned. For 
this reason I have refrained from attempting to describe many 
new species upon material so fragmentary in character, 
preferring, whenever possible, to refer the specimens provi- 
siorally to previously described species. 
JUNIPERUS HYPNOIDES, HEEp, 
tS oat ae 
The specimen identified as above was found by Mr. Wm. T. 
Davis, in a clay pit at Kreischerville. It appears identical with 
Heer’s species as represented in Flor. Foss. Arct. VI. 47, 48 ; Pl. 
XLIV. f.8 and XLVI. f.18. This is one of the best preserved 
specimens which we have from the clays and it was identified 
provisionally under the genus Juniperus when first brought to 
light. (Proce. Nat. Sci. Assn. S. I. September 10th, 1892.) 
The only other species with which I have thought this might be 
compared is J. macilenta, Heer. 
Frenevites Reicuu, Ett. 
Pl. I. f. 23. 
In many of the masses of clay examined, wherever plant 
remains were found, fragments and matted bundles of a conifer 
were generally prominent, which are almost certainly referable 
to this species, as represented by Ettingshausen in his Kreide- 
flora von Niederschcena, 246, Pl. I. f. 10a-10c, and by Heer, in
