254 Holden.— Some Fossil Plants from Eastern Canada . 
Voltzia coburgensis has been described by Schenk (loc. cit.) as abundant 
in the Lettenkohle, and Equisetum Rogersii , Schimper, is probably identical 
with E. columnaris described by Bronn, also from the Lettenkohle. This 
correlation applies only to Martin’s Head and the fossiliferous layers in the 
Trias of the eastern United States, so that, as pointed out by Wherry, 1 it 
is entirely possible that the Bunter below and the Rhaetic above may be 
represented also in the Connecticut Valley, New Jersey, Pennsylvania, and 
Virginia. 
Summary and Conclusions. 
1. There are present in the Trias of Martin’s Head, New Brunswick, 
specimens of a Conifer which, on the character of the pith cast, may be 
referred to Voltzia coburgensis , Schaur. 
2. The foliage of Voltzia coburgensis is Araucarian ; the organization 
of the cone, Abietineous ; and the anatomical structure intermediate 
between these two groups. 
3. Voltzia coburgensis seems to be another transitional form and 
presents additional evidence for the derivation of the Araucarineae from the 
Abietineae. 
4. Palaeobotanical evidence indicates that the Mesozoic strata of New 
Brunswick are of the same age as those of the eastern United States, and 
should be correlated with the Lettenkohle or Lower Keuper of Europe. 
In conclusion, I wish to thank Dr. E. C. Jeffrey for helpful advice and 
assistance in securing the photomicrographs accompanying this article. 
I wish also to express my thanks to Professor Arthur Willey, of McGill 
University, for the loan of a specimen of Voltzia coburgensis.
