JS. Newberry—Fossil Plants from Northern China. 125 
The Archeopteris indicates that the coal with which these 
plants were associated belongs near the base of the Coal-meas- 
ures, as this genus does not rise above that horizon. 
The species of Lonchopteris and Archeopteris are best repre- 
sented in the collection, and the former is very well shown. 
In general aspect it is not unlike the figures given by Brong- 
niart of his Z. rugosa, (Veg. Foss., p. 868, tab. 181, figs. 1, 2, 3), 
but the pinnules are smaller and the reticulation much more 
open. In the latter respect it is more like Z. Bauwrii Andr., 
L. Eschweilerianus Andr., and L. conjugata Goepp., sp. (Neurop- 
teris conjujata Goepp.), but it has narrower, more pointed and 
curved pinnules than either. ; 
Should a larger number of specimens show that these are 
constant characters it will be necessary to regard this as a new 
Species which may be fittingly named after Mr. Hague, Lon- 
chopteris Hagueana. The Archwopteris mentioned is a very 
graceful and well-marked species of the genus, having obovate 
or spatulate pinnules, of which the upper extremities are often 
crenulate or fimbriate. It is less robust than the type forms of 
- Hibernica Forbes, sp., and the pinnules are more symmetri- 
cal. It is about the size of A. Jacksoni Dwn,, but bas less 
crowded, more elongate, and more regularly ovate or spatulate 
world, and P. Hmmonsi, which occurs in North Carolina, 
all of which seem to represent the |
