 This plant oecurred in a hard, porous sandstone, the cementing material 

 of which was principally silica, with a very small per cent of iron; conse- 

 quently the diagnostic details of the fossils were not well preserved. The 

 plants shown in figs. 2 and 7 agree cU)sely with P. ohtusilolja from Missouri.^ 

 Locality: Liberty School. 



Pseuilopecuptrris cf. diiiiarpha Lx. 

 PI. II, figs, lb?, 4? and 5. 



The plant .shown in fig. 5, pi. II, is very close to the plant described by 

 Jjesquereux as Pseudopecopteris diinorpha. i^Mgs. lb and 4 may represent 

 P. 7rta«Zen/«,'" the material Ix'ing so fragmentary that determination is un- 

 certain.
