THE CEETACEOUS AND LAEAMIE OF CANADA. 35 



S. CoTJTTSi^, Heer. — Same locality, Upper Laramie. 



PoDOCARPiTES Tyrrellii, S.N. — YermlHou Eiver, Belly River series. Fruit globular, 

 flattened, with thiu coaly testa, marked with faint, interrupted striae. Diameter, 9 mm. 

 Obscure, pinnately attached leaves, resembling those of Podocarpus incerta of the English 

 Eocene are found with these fruits, and probably belonged to the same species. This is 

 the first appearance of the genus Podocarpus in our Upper Cretaceous. It is, however, 

 well-known in the European Eocene, and one species is recorded by Lesquereux from the 

 Tertiary of the United States. 



POPULXJS ARCTICA, Heer. — Many large and fine leaves. North Saskatchewan, west side, 

 Upper Laramie. This may be the same with P. cuneata, Newberry. 



P GENETRix, Neioby, or allied. — Same locality. Upper Laramie. 



P. NERVOSA (?) — Rocky Mountain House, Upper Laramie. 



Salix Laramiana, Dn. — Same locality. Upper Laramie. 



Carta antiquorxjm, Newby. — Same locality, Upper Laramie. 



Nelxjmbium Saskatchuense, S. N. — Leaves orbicular, peltate, with seven nerves. 

 Substance apparently thick and coriaceous. Diameter, two centimetres, or a little more. 

 The reference of these leaves, which are imperfectly preserved, to Nelumbium, is not certain. 

 They are, in any case, peltate, aquatic leaves, different from those of Brasenia antiqua, des- 

 scribed in the previous paper. 



Trapa borealis, Heer. — Leaves and fruit, Vermilion River. Belly River series. The 

 leaves are the same with Lesquereux's T. microphjUa. 



Viburnum Saskatchuense, S. N. — North Saskatchewan, east side, Upper Laramie. 

 These leaves are unusually broad, and with the veins well marked and less remote than 

 in any of the other species I can find described. The species may be thus characterised : — 

 Leaf thick, coriaceous ; broad-ovate, acumiuately pointed, somewhat cordate at base ; 

 ordinary length about three inches. Margin sharply and equally toothed. Midrib central 

 and strong. Veins strongly marked, at an acute angle to midrib, straight and forking 

 once or twice at their extremities, close together (about f,; inch). The direction of the veins 

 leaves a broad doubly-veined lower margin, with curved veins, the upper and principal 

 series five or six, and forking, the lower series short, much curved, and some of them 

 forking. Nervilles very close, fine and numerous, and angled or netted in the space 

 between the veins. These leaves, of which there are several well preserved specimens in 

 Mr. Tyrrell's collections, resemble in form some varieties of V. tilioides, Ward, and in the 

 venation V. Nordenskioldii, Heer. 



Viburnum asperum, Netvby. — Same locality, Upper Laramie. 



Sapindus, Sp. — Leaves small, short, unequally ovate, slightly acuminate. Midrib 

 distinct. Veins few, at a very obtuse angle. Margin entire. This leaf is very near to S. 

 obhisifolia of Lesq., and may be the same. Lesquereux's specimens are from the " Carbon 

 group," which is supposed to be later than the Laramie. 



V. — Concluding Remarks. 



While studying the specimens described on this paper, I received the volume of the 

 Palœontographical Society for 1885, containing the conclusion of Mr. Starkie G-ardener's 

 description of the Eocene couiferae of England. The work which he has been able to do.
