Mr. Wanner designated this as the ‘‘trunk of a conifer?” resting 
the case on the figures of Dr. Newberry. Professor Fontaine, how- 
ever, regards it as a Cycadeomyelon not hitherto described, and 
remarks: 
This is an imprint of the same kind as those Saporta has described, with the 
generic name Cycadeomyelon, in Paléont. francaise, Plantes Jurassiques, Tome II, 
pp. 331-332. He considers them as casts of partly decayed cycad trunks. The cigar- 
shaped prominences on this fossil are decidedly larger than those of Saporta’s C. het- 
tangensis. If it is worth while giving a name to it, it might be called Cycadeomyelon 
yorkense. 
Mr. Wanner gives the following account of it: 
Dr. J. 8. Newberry, in Mon. U. 8. Geol. Survey, Vol. XIV, p. 94, pl. xxvi, figs. 
1, 2, illustrates and describes what he supposed to be the decorticated trunk of some 
conifer from Newark, New Jersey. A similar impression from here, Fig. 1, Pl. XXX, 
comes from a locality which yielded nothing else. For that reason as well as because of 
the decorticated and compressed condition of the specimen, no additional light is 
shed upon the character of the trunk which produced it. Thin seams of carbonized 
vegetable matter are irregularly included in the overlapping folds that mark the 
specimen. The section, Fig. 2, is drawn at the point of greatest width. 
Locality.—Fox Run, one-eighth of a mile from its junction with the 
Little Conewago Creek. , 
There seems scarcely any doubt that whatever the stems from 
Newark may be, this one from York represents the same plant. Dr. 
Newberry’s fig. 2 is almost exactly the same as Mr. Wanner’s Fig. 1. 
Dr. Newberry refers to the specimen called Voltzta coburgensis Schaur., 
figured by Schenck in Paleeontographica, Vol. XI, pl. xlvi, fig. 2, and 
there certainly is a close resemblance between this figure and those of 
the American specimens.. 
It may not be out of place to draw attention to the somewhat similar 
class of objects which I have described under the name Feistmantelia.? 
The specimen from the Lettenkohl, near Wiirzburg, forms a sort of 
transition between some of the forms to which I there call attention 
and those now under consideration.
