pinne of my American specimens. On the fruiting speci- 
mens, which, however, are not very distinctly preserved, the 
rachis does not show any wing so far as I have been able to 
observe, but it is very broad. 
Fig. 4 gives an enlarged figure of a fruiting-pinna, and 
though badly preserved, it shows the general arrangement 
of the sporangia, from which one might be led to believe 
that the fern was Calymmatothecous. From the imperfect 
condition of the specimen, one cannot, however, risk any 
conclusive opinion on this point, for some of the pinnz seem 
to indicate a gradual reduction of the limb, which seems to 
have entirely disappeared from those pinnules which bear 
the sporangia; but even in these cases the apparent dis- 
appearance of the limb may be due to imperfect preserva- 
tion. 
My thanks are due to Dr Hind and to Mr W. Hemingway 
for the specimens which form the subject of this com- 
munication.
