coriaceous appearance, the midvein of the pinnule showing as 
a slight depression. The under side has usually a rough, 
wrinkled appearance, the midvein marked by a projecting 
line. The line referred to by Professor Weiss??? as running 
obliquely from the incision between the pinnules to the rachis 
is very distinct on well-preserved specimens, and runs to the 
midvein of the pinnule near or at its base or unites with the 
rachis of the pinna near the origin of the midvein of the pin- 
nule. The pinne in the middle part of the frond are oblique, 
2 cm. apart; the pinnules alternate, contiguous for some dis- 
tance, 8 to 11 mm. long, oblique, and recurved at the apex. 
Near the apex of the frond the pinnules are closer, connate, 
and decurrent along the rachis. The lateral veins are usually 
indistinct; they are oblique, slightly curved, simple, or occa- 
sionally forked. 
The variety C. conferta obliqua Goep. is apparently present, 
as is also C. conferta patens Weiss and C. conferta vulgaris 
Weiss. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county, and the Wreford limestone, six miles west 
of Reece, Chase formation, Washington, and from the Elm- 
dale shales, near Reece. 
Callipteris (2) sp. Pl. LXI, fig. 15. 
A small part of a frond from the Wellington indicates ap- 
parently a Callipteris of the type of the genus largely de- 
veloped in the Permian. The pinnules are subopposite or 
opposite, open, almost at right angles or sessile, gradually 
reduced in approaching the petiolate base, the lower pair be- 
ing very small. The lamina is thick and the venation in this 
Specimen entirely obscured. The fragment has some resem- 
blance to the small species of Glenopteris and may prove to 
belong to that genus. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county, and the Wreford limestone, six miles west 
of Reece. 
Callipteris cf. bergeroni Zeiller. Pl. LXI, fig. 7; pl. LXV, fig. 1. 
This Callipteris has a striking resemblance to C. bergeront 
from the Permian of Lodeve, France. The pinnules are, how- 
ever, larger, and the rachis stronger.
