Plate XIV, Fig. 4 

 Podocamitcs lanccolatus (L. & H.) Schimper, Pal. Veg., vol. 2, 1870, p. 160. 



This species has been noted by Dawson in the Kootanie of British 

 Columbia, but not before detected in beds of this age in the United 

 States. 



Locality. — Meridith mine, about 3 miles southeast of Nollar's 

 ranch and 6 miles southwest of Geyser, Cascade County, Montana. 



PODOZAMITES NERVOSA? Newberry 



Podosamites nervosa Newberry, Am. Jour. Sci., 3d.ser., vol. 61, 1891, p. 

 200, pi. xiv, fig. 6. 



Newberry's species was founded on a single leaflet which was 

 four inches in length, being "broadest toward the base, subacute at 

 the summit, with the nerves parallel, distant, strong." The collec- 

 tion in hand contains a single fragment, evidently from near the base 

 of a very large leaflet, that can hardly be referred to anything but 

 the present species. It of course adds nothing to our knowledge, 

 afid T'have even thought it best to question the determination. 



Locality. — Flood siding 5 miles southwest of Great Falls, Montana 

 [at or near type locality].
