IV. — Belly Eiver and Lauamie Series. 



I do not propose iu this paper to enter into a detailed description of the species from 

 the Belly Eiver and Laramie Ijeds now in my hands, but merely to state a' few focts sup- 

 plementary to those in former reports and papers, and in anticipation of fuller descrip- 

 tive lists which I hope to prepare in the future. 



Since the publication of my memoir of 1883, I have myself, with the kind aid of Mr. 

 Moses Burpee, then of Calgary, made considerable collections iu the railway cuttings at 

 Shaganappi Point, on Bow River, a few miles west of Calgary. Mr. S. R. Byrom, of Drylesden, 

 England, has kindly presented me with an .interesting new species from the Belly River 

 series of the South Saskatchewan, and Mr. Weston and Mr. Tyrrell, of the Geological 

 Survey, have made some A'aluable collections from the Belly River series and the Lower 

 Laramie, which have been placed iu my hands by the Director of the Geological Survey. 

 In connection with this, the recent report of Dr. G. M. Dawson has given us, for the first 

 time, a subdivision of the Laramie beds, and the local distribution of the several members. 



It is expected that additional specimens will be collected in the summer of 188-5, and 

 that it may be possible, next year, to present a somewhat complete account of the Laramie 

 flora and its several subdivisions, and also of the relations of this flora to that of the beds 

 underlying. Li the meantime, I shall here give notices of the more interesting new 

 species in the recent collections, and shall notice their stratigraphical distribution in the 

 next section. 



Brasenia antiqua, S. N. 



Leaves rounded elliptical, entire. Insertion of petiole nearly in the centre, with about 

 eighteen radiating veins forking about half-way to the margin, and a second time near the 

 margin, to join the marginal areolation. Form somewhat less elliptical than in the 

 modern B. peltata, and veins more numerous, but otherwise similar.

The specimens were obtained in the beds of the Belly River series of the Canadian 

 Survey, near Medicine Hat. These beds are Upper Cretaceous, and hold fossils, some of 

 which resemble those of the Laramie group, others those of the Pierre group. I place 

 their fossil plants with those of the Laramie, because the flora seems to be in the main 

 similar to that of the Lower Laramie. They contain workable beds of lignitic coal ; and
