that the two lots represent the same species. As we know it, the 
species is now represented by: — 
. The complete structure of the rhizome. 
. The rather complete structure of the stipe. 
. The foliage. 
- The fertile pinnules devoid of sporangia.

CTENOPTERIS COLUMBIENSIS, D. Sp. 
Upper Cretaceous of Port McNeil, Vancouver Island. 
This species is represented by a small fragment of a frond from 
Port MeNeil, Vancouver Island, and it embraces only three pinnules. 
The oblong pinnules ascend at an angle of 60 deg., and attain a

dimension of 7 mm. in width by 13 mm. in length. The margins are 
entire, the apex rounded and the base slightly decurrent. The eight 
or nine veins are prominent and fork from near the base. 
NEUROPTERIS HETEROPHYLLA, Brongn. 
Brongniart, Hist. des Veg. Foss., 1828, 243, LXXI. & LXXII. 
Lower Cretaceous of Alliford Bay, Queen Charlotte Islands. 
Three fragmentary specimens from Alliford Bay, Queen Charlotte 
Islands, represent the pinne of a fern showing the characteristic 
venation and forms of Brongniart’s Neuropteris heterophylla from the 
coal measures of Europe, and from which it cannot well be separated, 
but in view of the very different horizons in which they occur, it 
would seem expedient to designate the Alliford Bay specimen as 
N. heterophylla cretacea. The only other species recorded from the 
same horizon in neighbouring localities, is N. castor of Dawson, 
derived from the Upper Cretaceous of Vancouver Island, but this 
differs in such conspicuous ways as to admit of no difficulty in 
separation.
