very nearly 90 deg., or in one specimen, they show a more pronounced 
tendency to form a definite upward angle. They are extremely fine, 
numerous and closely packed, being exactly 3 to the millimetre. At 
the outer end, at a distance of about 7 mm. from the margin, they 
commence a slight upward curve which is maintained to the end. 
An examination of the records of similar plants from the same 
or neighbouring localities, shows the occurrence of Macroteniopteris 
vancouverensis, Dn., in the Upper Cretaceous of Nanaimo, Vancouver 
Island,* but this admits of no direct comparison with our specimens. 
Teniopteris plumosa, Dn., was described in 1883 by Sir William 
Dawson as occurring in the Upper Cretaceous at Baynes’ Sound, but 
the small size of the frond and the strongly developed upward angle 
(50 deg.) of the veins, at once excludes it from all comparison with 
the present forms. 
Ward figures and describes various specimens of Tæniopteris 
orovillensis from the Oroville beds of California. The essential 
features of his description show the frond to be narrowly elliptical, 
tapering gradually toward both base and apex, and attaining a pro- 
bable length of 26 em. The midrib is strong, prominent and rounded, 
while the lateral veins which are given off nearly at right angles, are 
parallel throughout, fine, closely packed and 3 to the millimetre, while 
they also curve slightly upward toward the end of the frond. The 
figures given? almost exactly duplicate one of our specimens. It 
will thus be seen that there is a very close correspondence between 
the plants from Port McNeil and those from the Oroville beds. Fon- 
taine’s original account of this species* gives nothing beyond the 
name and a discussion of the geological relations. 
The genus Tæniopteris as a whole, belongs to the earlier rather 
than to the later Mesozoic time, and with the exception of T. plumosa 
which represents a diminutive form, there is no previous record of 
its occurrence above the Lower Cretaceous, while it is very conspicuous 
in the Jurassic and Triassic formations. Tæniopteris orovillensis 
as recorded by Fontaine and Ward, is very abundant in the Oroville 
beds which Prof. Fontaine finds to be of the age of the Lower 
Oolite,* although in a later statement, he shows that the age cannot 
be so exactly defined, and that it may be anywhere between the 
Upper Trias and the Lower Oolite. The occurrence of the same 
species in the Upper Cretaceous may possibly be taken as indicating
