a number of pyritized fragments of leaves which show little evidence 
that can be utilized for purposes of identification. The locality is an 
entirely isolated one, but by close coinparison of the specimens with 
those from the more western localities, it is possible to draw the con- 
clusion that there is essential identity with specimens from 1428, and 
that 1428, 1430, 1433, 1436 and 471 are all of the same age, questions 
of the precise horizon within these limits to be determined in the fol- 
lowing discussion. 
A review of all the material embraced in the two collections, shows 
that it falls into two well defined periods—Cretaceous and Tertiary, 
and it is most gratifying to find in this connection that the tentative 
conclusions based upon the very imperfect material of the 1903 collec- 
tion have been fully sustained by our later studies. 
DESCRIPTION OF THE SPECIMENS. 
TERTIARY. 
— PICEA COLUMBIENSIS, n. sp. 
2 
This plant is represented by two parts — fragments of stems and 
cones. The cone (250) is represented by a single, but beautifully 
2 

preserved cast (Plate I), from which the following characters may be 
drawn :— 
Cone narrowly ovate or conical, 2.3 x 5 em.; the seales 0.6 x 1.1 em., the 
margins conspicuously but finely dentate. 
The fragments of stem are obviously from the terminal portions 
of branches of some coniferous trees, and from the character of the 
leaf scars, they are to be referred to the genus Picea. While these 
branches are not connected with the cones in any way, nor do they even 
occur in the same blocks of matrix, nevertheless they are from the same 
beds, and in the absence of any other representative of the genus, it 
is probably justifiable to conclude that they are of the same species 
and will be so considered. 
The plant here represented has no living relative with which it 
may be compared, but the general aspect and structure of the cone 
would seem to place it without doubt, among the red spruces to the 
cones of which it bears a strong resemblance with respect to general 
form and the character of the scales, though the dentate margins of the 
latter at first suggest affinity with P. nigra. 
Among the fossil representatives of this genus, all the recognized 
species are of Tertiary age and very few in number. The majority
