Genus CYCADITES Sternberg. 
CyrcapDITEs acutus Emmons. 
1856. Cycadites acutus Emm.: Geological Report of the Midland Counties of North 
Carolina, p. 330. 
1857. Cycadites acutus Emm.: American Geology, Pt. VI, p. 114, Ae. 81. 
In American Geology, Pt. VI, p. 114, fig. 81, Emmons describes 
a plant which he calls Cycadites acutus. There is in the collection a 
specimen which is clearly the original of fig. 81. The figure gives the 
general aspect of the plant fairly well, but it is erroneous in some 
points. The leaflets are not quite so stiff looking and thick as the 
figure shows them. None of them have their tips preserved, whereas 
the figure represents several retaining their entire original length. 
The leaflets were probably wider originally than they appear to be 
now, as their margins are slightly doubled under in the shale by pres- 
sure. The specimen shows that the general form, mode of insertion, 
and falcate curvature of the leafiets are well represented in Emmons’s 
figure. The point in which the figure is most misleading is the mid- 
nerve of the leaflets. It is wider than is given in the figure. The 
midrib might, as now seen, be exaggerated by pressure. It seems to 
separate the leaflets from base to tip into two narrow parts, which 
look like two very narrow leaflets, so that they appear to be placed 
in closely approximate pairs. 
CYCADITES TENUINERVIS Fontaine. 
Pl. XLII, Fig. 1. 
1883. Cycadites tenwinervis Font.: Older Mesozoic Flora of Virginia, Mon. U. S. Geol. 
_ Survey, Vol. VI, p. 84, pl. xliv, figs. 4-6. 
Three specimens of a cycad were found in Emmons’s collections that 
are exactly like Cycadites tenuinervis, a plant found in the Older Mes- 
ozoic of Virginia, and not hitherto noted in the North Carolina beds. 
They show the falcate curvature of the leaflets and the slender, rather 
vaguely defined midrib that are characteristic features of the Virginia 
fossil. 
The specimens are portions of leaves, showing a number of closely 
placed leaflets, that, in the different imprints, show considerable vari- 
ation in size. The smallest are about 1 cm long; the longest are 2 cm. 
in length. They are widest near their bases and taper gradually to 
their ends, which are lancet-shaped and rather obtuse. Emmons does 
not give their locality. The general aspect of the leaflets is much like 
that of Ctenophyllum Braunianum var. 8, and, but for the midrib, 
they might be taken as belonging to this plant. They have a thick tex. 
ture and are about 2 mm. wide in their widest part.
