C.—(Odontopteris) varia, Dn. (Referred by Dawson to Nephrop- 
teris, but the latter name would refer only to the larger pinna he has 
figured under this name; the smaller figure, which is the basis of his 
description is Odontopteroid. 
Neuropteris serrulata, Dn. (This appears to be the same as 
Pecopteris serrulata, Dn., which see; it has not the venation of a Neu- 
ropteris). 
Neuropteris (Megalopteris, Dn.) Dawsoni, Hartt. 
Group SIGILLARIÆ. 
Following Sir Wm. Dawson, we have here separated Sigillaria from 
the Lepidodendra with which it is usually classed; true Lepidodendra 
appear to be unknown in this flora, if existant at this time they were not 
denizens of the delta and lagoons of the Little River Group, or at least 
were rare there. 
Sigillaria palpebra, Dn. (The leaf scars are small and obscure.) 
Stigmaria perlata, Dn., is placed here on account of the usual 
connection in the Coal Measures between this genus and Sigillaria 
and Lepidodendron. 
Group CORDAITES. 
The plants of most advanced structure in this flora are Dadoxylon 
and Cordaites, the former based on stems the latter (so far as the study 
of this flora by Sir Wm. Dawson is concerned) on leaves. But the very 
great abundance of the leaves of Cordaites, and of the fruit called 
Cardiocarpon cornutum Dn.,in this flora, leads one to infer the association 
of these objects in the relation of leaf and fruit of the same plant. Prof. 
D. P. Penhallow has described Dadoxylon Ouangondianum, Dn., as a 
Cordaites. : 
Dadoxylon Ouangondianum Dn. 
Sternbergia (or Artisia)—a pith mould of Dadoxylon. 
Cordaites Robbii, Dn., (and perhaps other species, not separated.) 
? Cordaites angustifolia, Dn. (This plant is probably different 
from the Devonian (Gaspé) type specimens of this species described 
by Sir Wm. Dawson. 
Cardiocarpon cornutum, Dn. 
C.—Baileyi, Dn. 
Fruits or UNDETERMINED RELATION. 
Whittleseya is listed with the Neuropteris Group, but its connection 
there is not established.
