THE EOCKY MOUNTAIN REGION OF CANADA. 7 



Zamites MONTANA, S. N. (Plate I. Figs. 6, 6a.) 



Frond narrow, elongate, pinnate. Midrib strong and as broad as the pinnœ, which 

 are contiguous, parallel-sided, very obtusely truncate, almost rounded at both extremities, 

 thick and coriaceous, with four parallel veins, which are visible only on the under side. 

 Ordinary size of pinnules *7 millimetres long and 2 millimetres broad. This is near to 

 Heer's Z. arctica and Z. hrevipennis from the Lower Cretaceous of Komé, Greenland, but 

 has broader leaves than either, and is altogether larger. It is, perhaps, a variety proper to 

 a more southern latitude. 



Collected by Gr. M. D. at Martin Creek and Kootauie Pass. 



Zamite!^ acutipennis, Heer. (Plate I. Fig. ô.) 



Heer, Kreide Flora der Arctischen Zone. 



This is a fragment of a frond, with pinnules not distinguishable from Heer's species, 

 which is found in the Lower Cretaceous of Ekkorfat, Grreenland. 



Collected by G. M. D. at Martin Creek. 



Zamites, Sp. (Plate L Fig. 4.) 



An imperfect leaf, like Z. boreaiis of Heer, as represented in Kreide Flora, Table XV, 

 but too imperfect for certain determination. 



Collected by Ci. M. D. at entrance to Kootanie Pass. 



Anomozanites acutiloba ? Heer. (Plate L Fig. T.) 



Heer, Jurassic Flora, Ost-sibiriens, PI. XXIV. 



Pinnate, pinna? broad and short, oblicjiie, rounded at their extremities, contiguous, 

 attached at base, with numerous parallel veins, at right angles to the petiole. 



The fragments of this leaf indicate a form very near to A. Schmidtii and A. acutiloba from 

 the Jurassic of Siberia, more esjjecially to the latter. 



Associated with these leaves are racemes of sessile fruits, referable to the genus Cyadeo- 

 carpus, and which may have belonged to this plant. 



Collected by G. M. D. near Caumore. 



Sphenozamites^, Sp. 



A single imperfect leaflet in the shale of Martin Brook, indicates the presence of a 

 cycadaceous plant, probably of this genus. The specimen resembles a leaflet of S. lalifolhis, 

 Brongt, of the Upper Oolite.

Antholithes horridits, Daivson. 



Trans. Roy. Soc. Can., Vol. I. Sec. IV. p. 21, PI. I. Fig. 3. 



A few fragments of the radiating processes of this remarkable fruit indicate its pre- 

 sence in the beds at Middle Branch, North Fork, Old Man River. Withoi^t the perfect 

 specimen from Peace River, described in my former paper, it would have been impossible 

 to recognize these fragments. 



Collected by G. M. D. 



It will be observed that though some of the above species are represented by speci- 

 mens too imperfect for detailed description, these are sufficient to establish their distinct- 

 ness as species, and their reference to the Cycadeœ. We thus have evidence at the same point
