wide. The basal pinnule on the lower side of each pinna is 
much enlarged, unequilateral oblong-ovate, deflexed, lying 
along the rachis, lower side straight and close to the rachis, 
upper side rounded. Veins originating from the rachis with- 
out a midrib, or the central vein merely stronger than others, 
spreading, several times 
dichotomous, fine, numerous; 
lower ones strongly arched, 
counting about 40 to the centi- 
meter. | 
The Kansas specimens are 
very similar to the species as 
figured by Weiss (Foss. Flora 
der Jungs. Stien. Form.) and 
seem to agree essentially with 
the French specinens in the _SS>=>== 
National Museum with which 
I have compared them. The Pinnule of Odontopteris reichiana. 
deflexed basal pinnules, how- 
ever, do not seem to have been previously observed, and the 
pinnules of the species as developed in the Wellington shales 
are rather large. The venation of one of the pinnules is shown 
in the accompanying text figure. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county; Chase formation, Washington. This spe- 
cies has been identified by Lesquereux from Thayer, Kan. 
(Recorded by White, Bull. U. S. Geol. Surv., No. 211.) 
Odontopteris minor Brongn. PI. LXII, fig. 17. 
This species occurs rarely at the Banner City locality. It 
is one of the few species common to the Douglas formation 
and the Wellington shales.
