SELLARDS.| Fossil Plants, Upper Paleozoic, Kansas. 403 
The species is represented by a great number of fragments 
from University Hill, preserved in a clayey shale, in which the 
venation seldom shows. The few pinnules in which the vena- 
tion is preserved show the veins to be rather distant, thin, 
oblique, forked once in the small pinnules, perhaps simple in 
the very smallest, the upper vein forking again in the large 
pinnules, always at a wide angle; the first dichotomy close to 
the midrib, never more than one-third of the distance to the 
border. The fructification on these fragments from University 
Hill is too indefinite to figure, appearing only as roughened 
punctate-like dots covering the surface of the fertile pinules. 
The Twinmound concretions have some fructified specimens 
very well preserved, from which figure 14, plate XLV, is taken. 
The sori in these are seen to be placed irregularly over the 
surface, but with some approximation to two rows on each 
side of the midrib. The sori are nearly square and seem to be 
distinctly divided off into four compartments. The specimens 
are from University Hill, except the figured specimen from. 
Twinmound. 
Formation and locality: From the Lawrence shales, at Law- 
rence and Twinmound. 
Aphlebia PRESL. 
Aphlebia pinnules are numerous in the collections. A few 
of the more unusual are illustrated. The pinnule of figure 9, 
plate LVI, is found at Twinmound. A hirsute Aphlebia with 
short lobes, found at the Haverkampf farm in the Le Roy 
shales, is shown in figure 3, plate LV. 
Spiropteris SCHIMPER. 
The coiled apices of young fern fronds such as are usually 
referred to in fossil botany literature as Spiropteris occur not 
infrequently in the collections from both the Coal Measures and 
Permian formations. 
Neuropteris BRONGNIART. 
Mem. Mus. Hist. Nat., vol. 8, p. 333, 1822. 
Neuropteris gilmani sp. nov. Pl. LVIII, fig. 4. 
Pinnules very large, 414 cm. broad, 11 mm. long, irregular 
in shape, ovate acuminate, sessile, base inequilateral, strongly 
auricled, having a large, nearly square lobe below, borders at 
first nearly parallel then sloping to an acuminate apex, irreg- 
ularly undulate. Veins fine and numerous, about 45 per centi-
