keilhaui described by Nathorst?° from the Upper Devonian of 
Bear Island. A stronger resemblance is shown to certain sterile leaf 
segments from the same locality, correlated by Nathorst with 
Cephalopteris (Cephalotheca) mirabilis” 
which will be treated more fully under the discussion of the seeds 
and microsporangia. The character of the pinnules is shown in

Fig. 4 Part of the frond of Eospermatopteris showing the ultimate pinnae 
with the pinnules. (Reduced slightly more than one-third) 
figures I-4 on plate 10. They are twice bilobed with the divisions 
of the first bifurcation more or less recurved; and they do not nar- 
row down proximad but join the stem by a broad base. The first 
bifurcation occurs at about half the length of the pinnule ; the second 
bifurcations are near the tips which appear to be blunt and rounded.
