This species, several fragments of which have been found in the collec- 

 tions, may be easil}^ distinguished from Neuropteyis missovriensis Lx. by the 

 coarse, rather distant, arching veins forking at a wider angle, while the pin- 

 nules are rather more distant, longer proportionately, narrower, often with a 

 slightl)' sinuous margin, and generally dilated somewhat at the base. The 

 species is described at length in my report on the flora of the outlying coal 

 basins of Missouri.^ Neuropteris rarinervis Bunb. is possibly indistinguish- 

 able from Neuropteris coriacea Lx., with which the specimens in hand seem 

 to agree equally well.
