 are, however, twice as large as that ligured, and with the angle of venation rather less 

 acute.

10. Menispermites renmformis, S. N. (Fig. 1-J.) 



Leaf broad, reniform. 11 centimetres broad and 7 centimetres in length, margins 

 tmdulate. Five veined, but with two accessory veins, making 7 in all. Tliis is a very 

 remarkable leaf, but of somewhat uncertain alhnities.

This leaf is very imperfect, but approaches nearly in its venation to tlic species named. 



Collected l)y Dr. Selwyn at Peace River. 



18. Protophym.u.m boreale, S. N. (Fig. 18.) 



Leaf very large, rounded at base, wliiili extends 2 to 5 centimetres beyond the attachment 

 of the petiole. Venation based on three main ribs, springing from the midrib near its base, 

 and w^hich are connected with each other by veins angling upward. The lateral veins give 

 off regular secondary veins toward the margin. The portion figured is the basal part of a 

 large leaf, whi>li some fragments show to have Ijeeu six inches or more in its greatest 

 diameter. 



Collected by Dr. Selwyn at Peace Eiver. 



19. PROTOrilYLLU.AI RUGOSUM. 



Lesquereux, Cretaceous Flora, p. 105, pi. XVII. 



A leaf not very well preserved, but so far as can be seen not distinguishable from that 

 above named, which is from the Dakota Grrouii.

A(l(lUioiiiil liihuid Species. 



20. PiNus Susquaensis, S. N. (PL III., Fig. 37.) 



Leaves, long linear, about 3 inches in length, and 8 or more in breadth, replaced by a 

 micaceous mineral in hard black slaty rock. 



21. Laurus crassinervis, S. N. 



A narrow lanceolate leaf, resembling L. Nebniscensis of Lesquereux, but more parallel- 

 sided and with very strong channelled midril). having transverse wrinkles. No trate of finer 

 venation. 



Both of the above species are from the deposit in Susqua River already referred to, and 

 believed to be of Cretaceous age.
