132 FLORA OF LOWER COAL MEASURES OF MISSOURL 



The fronds of Neuropteris missouriensis were evidently of considerable 

 size, some of the frag-ments of attached rachis measuring as much as 9 nmi. 

 in width. The large Cyclopterid leaves described as N. dUatata (L. & H.) 

 Lx., if they really belong to this genus, are jjrobably rachial pinnules of N. 

 missouriensis. So far do they ag-ree, however, in the essential superficial 

 features with those of similar form and dimensions placed by foreign 

 authors in the genus Doleropteris that a generic identification with the latter 

 tends to affect the systematic status of the Neuropterid group.

IfElTROPTERIS FASCICULATA Lx. !

A single broad, ovate, acute pinnule in the collections appears to be 

 identical with Neuropteris fasciculata Lx., as seen in specimens from Mazon 

 Creek, Illinois. It has much in common also with N. acuminata (Schloth.) 

 Brongn., both in nervation and in general form. There ference of the frag- 

 ment to this species is merely tentative.
