CLADOPHLEBIS. 91 
V. 2197. Portions of seven pinne with the rachis very pro- 
minent. In many of the pinnules the midrib is fairly well defined, 
but the venation as a whole is much less distinct than in the 
figured specimen (V. 2204). Ecclesbourne. Rufford Coll. 
V. 2203. Fragments of pinne showing distinct venation. In 
these pieces the central axes of the pinne have a well marked 
longitudinal groove; the individual pinnules show the specific 
characters clearly. Ecclesbourne. Rufford Coll. 
V. 2210. This specimen shows part of the main rachis, and the 
manner of attachment of the pinne. LEcclesbourne. ufford Coll.

‘‘Neuropteris fronde pinnata (bipinnata?) pinnulis tenuibus 
oppositis distantibus, sessilibus, oblongis, basi rotundatis vel 
subcordatis, apice attenuatis, subobtusis; nervo medio crassiusculo,
