DESCRIPTION OF SPECIES. 53 
instructive. Ettingshausen has described in his Kreideflora von Nieder- 
schoena two cones which may not be different from ours. Of these those 
represented on PI. I, figs. 4-6, may be compared with our fig. 6 on Pl. VII, 
and are perhaps immature, while fig. 9 of the same plate, which was called 
Cunninghamites oxycedrus by Sternberg, is very much like our larger cones, 
and yet it is not known that a Brachyphyllum similar to that found in the 
Amboy Clays occurs in the Niederschoena beds. Another cone not unlike 
this is figured and described by Lesquereux in his Cretaceous Flora, p. 114, 
Pl. XXIV, fig. 1, with the name Ptenostrobus nebrascensis. Mr. Lesquereux 
does not attempt to connect this cone with any other plant, but points out 
its resemblance to Cunninghamites oxycedrus. Finally, I would call atten- 
tion to the striking resemblance between the scale-leafed conifer now figured 
and that which Velenovsky calls Echinostrobus squamosus (Gymnospermen 
der Bohmischen Kreideformation, p. 16, Pl. VI, figs. 3, 6, 7, 8).

LDibocedrus cretacea Heer, Fl. Foss. Arct., Vol. VI, Abth. IT, p. 49, Pl. X XTX, figs. 1, 2; 
Pl. XLIII, fig. 1d. 
Professor Heer (loc. cit.) has carefully figured and described what is 
apparently the plant of which we have found numerous twigs in the Amboy 
Clays and of which I have given a figure as indicated above, yet he con- 
siders the plant a species of Libocedrus, while to my mind it is much 
nearer to Thuya. In our living Libocedrus, as well as our fossil ones, the 
joints of the twigs, or rather the appressed leaves which cover the woody 
axis, are much longer and wider above, having a club-shaped outline; 
whereas in Thuya the four rows of appressed leaves, forming a joint or 
whorl, are of nearly equal height and breadth, so that the twigs are strap- 
shaped, the sides nearly parallel, just as in the fossil before us. I can 
detect no differences, however, between the specimens from New Jersey 
and Greenland. 
Locality : South Amboy.
