 In the collections of 1905, under number -— — , there were two impressions 



od. 



of cones which obviously represent a species of pine (PL II.). They are entirely 



free from associated foliage or other portions of the tree by means of which they 



might be more fully determined and correlated with known species. 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 cm. broad and 

 3 mm. thick at the upper ends, strongly and transversely keeled and terminating in 

 depressed, round or transversely elongated umbos without ( ?) prickles. 



Prom the above description it is quite clear that the cones represent a 

 hard pine, and upon careful comparison with the excellent figures and descrip- 

 tions 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 identical, 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 independent determinations brought the two to substantially the 

 the same species.

m, of 1905. 



In 1904 I described a new wood, found among the undescribed specimens in 

 the Peter Redpath Museum, under the name of Cupressoxylon 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 main, they are much 

 better preserved. That this genus has already been recognized as an element 

 of both the Cretaceous and Tertiary floras, has been shown on former occasions, 

 and especially by the occurrence of C. dawsoni, Penh., in the Eocene of the 

 Great Valley and Porcupine Creek groups, as well as in the Cretaceous of the 

 South Saskatchewan, near Medicine Hat (47). This extended geological range 

 is quite in harmony with the idea that the genus as a whole is an old one, and 

 that the present species is ancestral to, if not in all respects identical with the 

 existing C. macrocarpa.
