broad angle, are more or less zigzag in their course, curve 
strongly, and meet the border at an oblique angle. 
Formation and locality: Le Roy and Lawrence shales, Law-

This species differs from N. elrodi Lesqx. in that the rachis is 
distinctly striated and the terminal pinnule has a cordate base 
similar to that of the lateral pinnules. The pinnules are some- 
times very close and overlapping. 
Formation and locality: From near the base of the Bethany 
Falls limestone, Kansas City, Kan.

This species seems to be rare at Lansing. Mr. Gilman has, 
however, obtained a few specimens which appear to be typical 
of the species.

Fronds bipinnate or more. Ultimate pinnze subopposite, 
open or slightly oblique, close, lanceolate, terminated by an 
elongate-lanceolate pinnule. Rachis striate. Pinnules alter- 
nate, close, sessile by the entire base, oblique or open, oblong- 
ovate, obtusely rounded, sometimes contracted a little below the 
middle, smaller ones slightly united at the base, larger almost 
or quite free. Basal pinnules fan-shaped, ovate, deflexed ; pin- 
nules gradually passing into and becoming connate with a 
lanceolate or elongate obtuse terminal pinnule. Venation dis- 
tinct. Veins very numerous, 36 to 40 per centimeter at the 
border. Median vein little developed in the small pinnules; in 
the large pinnules, however, a fascicle is traceable half the 
length of the pinnule; branches numerous, fine, forked from 
two to five times, last division often close to the border. Ra- 
chial veins numerous and arising directly from the rachis, ex- 
cept in the case of the large pinnules, which have the median 
fascicle developed to some extent. 
The Kansas plant seems to agree with specimens from the 
Commentry deposits of France which I have seen in the Na-
