angle of 45 to 60 degrees, lower veins arising directly from 
the rachis. 
The larger pinnee of this species reach a length of 20 cm. 
The pinnules of these large pinne are but slightly or not at all 
connate at the base. Near the tip of the pinna the pinnules 
become connate and decurrent at the base. The pinnules are 
irregular in size, shape and inclination to the rachis. As a 
rule, the basal pinnules are deflexed. The midvein is strong 
and continues to near the apex, where it terminates suddenly. 
The lateral veins fork once near the midvein. Occasionally 
they are simple. 
Formation and locality: This species is abundant in the 
Le Roy shales, and has been obtained from the Scranton shales 
at Scranton. Mr. White (Bull. U. S. Geol. Survey No. 211, 
p. 112) records its presence at Thayer.

No. 4, p. 423, 1854. 
This species is present in typical form at Lansing in the 
Cherokee shales. The large pinne have pinnules irregular in 
size and shape, some being broad and short while others are 
more slender and longer. 
Formation and locality: Cherokee shales, Lansing. 
Callipteridium sp. Pl. XLV, fig. 22. 
An undetermined species of Callipteridium occurs at the 
Haverkampf locality in the Le Roy shales. The pinnules are 
found occasionally in the concretions from that locality.
