belongs, and there is no present evidence to show that they 
did, but I think the unique character of this plant will 
justify us in regarding it as of a new genus, for which I 
would suggest the name Zosterophyllum, to be specifically 
known as myretonianum. It must be clearly understood, 
however, that the application of this generic name is not 
intended to denote affinity with Zostera, but merely a gen- 
eral resemblance. 
Closely associated with Zosterophyllum, I found a branch 
bearing rounded and ovoid sporangia like bodies (Plate I, 
fig. 1) which are given in the figure of natural size. It will 
be seen that there are two conspicuous lateral processes or 
branches, the uppermost of which bears a distinctly globular 
body or sporangium (?). Above the second sporangium 
there is a short fragment of stem which probably represents 
a continuation of the same axis. The sporangia show no 
subtending bracts, nor is any structure visible. They are 
in each case completely flattened out so that only the im- 
pression remains. 
A second fruiting branch of the same nature, but with 
less mature fruit, is shown in the drawing of natural size 
(Plate II, fig. 2). This is much more intimately associated 
with Zosterophyllum than the preceding, being completely 
surrounded by leaves and branches from which it was at 
first difficult to separate it. Both agree in their essential 
features, but as in neither no actual connection was found 
to exist with Zosterophyllum, it is impossible to say what 
the precise relationship is, though from their general form 
and structure we might infer that these fruiting spikes 
were thrown up direetly from the horizontal rhizome. 
It is highly probable that the round, seed-like bodies 
(Plate II, fig. 3), which also occur abundantly, and which I 
was unable in my former paper,' to satisfactorily account 
for, are the same fruits in a mature condition. These bodies 
show a very slight carbonaceous film surrounding a mass 
of slaty stone as a nucleus, thus lending probability to the 
view that they represent sporangia, the contents of which
