Genus CEPIIALOTAXOPSIS Fontaine. 



Cepualotaxop.sis kamosa Fontaine?" 



PI. LXXIII, Flo-, s. 



A mmiber of imprints of detached leaflets were found on several 

 pieces of the Geyser shale tliat closely reseml)le leaflets of CepJialolax- 

 o])sis ramosn Font., a plant found rather abundantly in the Lower Poto- 

 mac l)eds of Virginia. Xone of these were found attaclied and they 

 are all fragments of leaflets. Their texture is leathery, hut rather thin 

 for a Cephalotaxopsis, and they have a strong single nerve. They 

 appear to be certainly leaflets of some Cephalotaxopsis, but are not 

 well enough preserved and sufficienth' abundant to disclose clearly 

 their specific character. The}- agree best with the narrower form of 

 leaflets of C. ramosa. 



Genus NAGEIOPSIS Fontaine. 



Nageiopsis longifolia Fontaine. 



PI. LXXIII, Fig. 9. 



Five or six fragments of shale from the ({eyser strata show imprints 

 of pieces of strap-shaped leaflets with parallel nerves that have the 

 character of Nageiopsis longifolia Font., a conifer foimd first in the 

 Lower Potomac beds of Virginia. The imprints are all of fragments 

 of leaflets, the longest being from .o cm. to 6 cm. in length, with a width 

 of 5 cm. or 6 cm. None of them are attached, Itut one specimen shows 

 the basal portion of a leaflet with the characteristic narrowing seen 

 in .V. longifolia. which gives the base of the leaflet an elliptical from. 

 This plant does not seem to be common in the Geyser strata.
