The specimen referred to this species agrees very closely 
with examples of Sphenopteris solida from the type locality at 
Mazon Creek, Illinois, with which I have compared it. The 
pinnules are long and deeply lobate. The venation is obscured, 
except at the bases of the pinnules and in the lobes. Fine striz 
are sometimes visible in the epidermis. The plant is much like 
fi. bilobata, from Clinton, Mo., which White has provisionally 
separated as a distinct species. 
Formation and locality: A few specimens have been obtained 
from the State Penitentiary mine at Lansing, Kan., about 100 
feet below the top of the Cherokee shales.

Eremopteris missouriensis Lx., David White, Flora of the Lower 
Coal Measures of Missouri, p. 16, pl. 5, figs. 1-3; pl. 6, 1899. 
The single fragment which I refer to this species has pin- 
nules larger, more distant, the lobes broader, than those of the 
type specimens or those from Missouri figured by White (loc. 
cit.) The nervation, so far as it can be made out in the thick 
epidermis, agrees with the types. The midvein of the pinnules 
is seen to be decurrent at the base to the flat, winged rachis, 
forked and sending branches into the obtuse, or sometimes 
bifid, lobes. The character of the lamina, roughened and finely 
lineate with short scales, is very similar to that of the Missouri 
specimens. 
Formation and locality: Cherokee shales, Lansing, Kan.
