Odontopteris excelsa sp. n. Pl. XLIX, figs. 7-9. 
Fronds large, bipinnate or more. Ultimate pinnez long, 
linear or linear-lanceolate, reduced at the top of the frond, 
passing gradually into pinnatifid and simple pinnules. Pin- 
nules large, open or inclined forward, oblong-ovate, obtuseiy 
rounded, sessile, large ones free to the base; smaller ones con- 
nate, divided by an acute sinus; pinnules of the ultimate pinnz 
passing into lobes of a large, obtusely pointed terminal pinnule. 
Texture thin. Veins distant, distinct, arising from four to 
five rather thick decurring basal facicles, of which the one 
supplying the apical part of the pinnule is the stronger and 
has several branches. 
This characteristic species is closest perhaps to O. lingulata 
by the large terminal and broad lateral pinnules, but is dis- 
tinguished by the fewer and more distant veins arising from 
four to six basal veins, while in O. (obtusa) lingulata nu- 
merous fine veins spring from the base. 
The largest ultimate pinne preserved, 13 cm. long, is in- 
complete. The lower pinnules, such as shown in figure 7, 
plate XLIX, are very broadly ovate, squarish, free to the 
sessile base, slightly rounded at the apex. The smaller pin- 
nules above are inclined forward a little, obtusely pointed. 
Another specimen shows the pointed penultimate pinne end- 
ing in a terminal pinnule. 
Formation and locality: LeRoy and Lawrence shales at 
Lawrence, the Scranton shales at Osage City, and the Chase 
formation at Washington. 
Odontopteris minor Brongn. Pl. XLV, fig. 21. 
This species occurs rarely in the Le Roy shales at the Hay- 
erkampf farm. The specimens obtained have been for the 
most part fragments of pinne. The agreement with the 
European specimens of O. minor seem to be satisfactory. 
This species has been recognized also from the Wellington 
shales at Banner City.

This species occurs at Lansing but is not very abundant. 
The lateral veins are thin, nearly straight or somewhat wavy, 
simple or forked once at irregular distances from the midrib,
