There are few good figures of this species, therefore 
I have indicated those generally accessible. The two spec- 
imens from Pennsylvania are slightly larger than those 
from Europe: 
A. length=388 mm.; max. width=18 mm.; min. 
width =15 mm. 
B. length=29 mm.; max. width =14 mm.; min. 
width =10 mm. 
Neither is complete so it is not known if the leaf-base 
was petiolate or decurrent. The mid-rib is slender, the 
secondary veins depart at an angle of 45 degrees and al- 
ways fork twice near the departure from the mid-rib. 
The branches of the secondary veins frequently fork again 
near the entire margin. These characters are similar to 
those usually found in European specimens, but are in 
certain respects unlike those of T‘\/escuriana which is 
much larger (10 cm.) and has a more slender mid-rib. In 
T.lescuriana the branches of the nerves rarely fork near 
the margin. 
Potonie” gives the distribution of 7. jejunata as 
Floras VI to VIII or in other words, from the Upper 
Ottweiler (=Stephanian) to the Lower Rotliegende. 
The same range is given by Gothan” who states that it 
is essentially Permian although it appears in the Upper- 
most Carboniferous. Bertrand” lists 7°. jejunata among 
the characteristic plants of the Saint-Etienne flora (Ste- 
phanian) of France. No undoubted records of this or of 
any other Taeniopteris occur earlier than the Stephanian 
stage of the Carboniferous. Lesquereux’’” has described 
two Pottsville (= Westphalian) ‘“Taeniopterids.’’ The
