one on the lower side being decurrent and united with the 
rachis. Midvein rather strong, continuing to near the apex, 
where it becomes a shallow furrow, decurrent at the base. 
Lateral veins not distinct; they leave the midrib at an angle 
of approximately 45 degrees, curve outwards to the border, 
apparently forking once, or simple in the smaller pinnules. 
The veins passing into the lobes of the lobate pinnules fork 
once. The species is named for Mr. David White. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county. 
Callipteris elongata sp. nov. Pl. LXI, fig. 16. 
Ultimate pinne linear. Pinnules alternate, very oblique, 
curved back a little at the apex, decurrent, oblong, obtuse at 
the apex, largest a little above the middle, contracted at the 
base, rounded above the base, borders sinuous, texture thin. 
Venation fine. Midvein continuing to the apex, decurrent at 
the base, entering the pinnule near the upper side of the base. 
- Lateral veins oblique, those on the upper side nearly straight 
or but slightly curved, those on the lower side somewhat more 
curved, forked. Rachial veins supply the decurring base. 
This species is not abundant, a few specimens only having 
been obtained. The most closely related form that has come 
to my notice is from the Lower Permian of Italy, figured by 
Stefani (Flora Carb. et Perm. della Toscany, pl. 8, fig. 7) as 
a form of Callipteris conferta. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county. 
Callipteris sp. Pl. LXIV, fig. 2. 
The frond or division of a frond illustrated here and be- 
longing with little doubt to the genus Callipteris resembles 
types of that species found in the Permian of France and 
figured by Zeiller (Bassin d’ Autun and d’ Epinac), although 
apparently specifically distinct from any of these, from. all 
of which it differs in having a petiolate frond or division of a 
frond with the pinnules toward the base reduced. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county.

C. conferta is one of the very abundant species in the Per-
