tracheids small and not numerous, those on the radial walls rather 
large, round, or oval in one compact row, and generally numerous. 
Tangential.—Fusiform rays rather numerous, short, the broad central tract with 
thin-walled parenchyma chiefly broken out: the unequal terminals com- 
posed of broad, oval cells chiefly in one row. Ordinary rays low to 
medium, uniseriate, not materially contracted by the interspersed 
tracheids; the parenchyma cells somewhat unequal and variable from 
oblong (in the summer wood) to broad and oval or round (in the 
spring wood).

In the collections of 1905, under number Sa ? there were two 

impressions of cones which obviously represent a species of pine (PI. IT). 
They are entirely free from associated foliage or other portions of the 
tree by means of which they might be more fully determined and corre- 
lated with known specis. Although somewhat distorted by displacement 
of their matrix, their essential characters are fairly well preserved and 
may be described as follows :— 
Cones narrowly ovate or oblong ovate; the scales upwards of 1.1 em. broad 
and 3 mm. ‘thick at the upper ends, strongly and transversely keeled and ter- 
minating in depressed, round or transversely elongated umbos without (?) prickles. 
From the above description it is quite clear that the cones represent 
a hard pine, and upon careful comparison with the excellent figures 
and descriptions given by Sargent (55), it becomes apparent that they 
are most directly comparable with P. glabra among existing species. 
Although the two localities for the stem and cones are not iden- 
tical, they represent the same horizon, and probably the same deposits, 
so that in view of the essential relationship established above, it is 
probably justifiable to consider that both cones and wood represent 
the same species. This view is strengthened by the fact that indepen- 
dent determinations brought the two to substantially the same species.

LU CUPRESSOXYLON MACROCARPOIDES, Penh. 
In 1904 I described a new wood, found among the undescribed 
specimens in the Peter Redpath Museum, under the name of Cupress- 
oxylon macrocarpoides (47), because of its striking resemblance to the 
existing Cupressus macrocarpa, with which it is possible it should be 
fully identified under the same name, but of which it is to be regarded 
as the ancestral form in any event. These woods were all recorded as 
from the Cretaceous formation near Medicine Hat, Alberta, the precise 
locality being Twenty-Mile Creek. 
In the 1905 collection from the Kettle river, large numbers of 
specimens representative of this tree were again met with, and in the
