small a fragment, however, for rigid determination. It rep- 
resents a small-leaved species with leaves apparently about 
the same size as those of Velumbo Laramzensts Hollick (7. ¢. 
J in text); the cross venation is obliterated, however, and the 
primary veins are only eight in number instead of twelve, as 
is the case in WV. Laramdensis.* Nelumbo tntermedta,t 
of the Montana formation, is of about the same size, but has 
twelve or thirteen weak primary veins. MVelumbo Dawsoni 
Hollick, + from the Canadian Belly River, is also a small 
leaf, but has eighteen primary veins. Dawson has de- 
scribed,§ but not figured, a small leaf from the Canadian 
Laramie, under the name of Velumbium Saskachuensts, of 
similar size and with only seven primaries. 
MAGNOLIACEAE. 
Maenousa Linn. Sp. Pl. 535. 1753.

is as follows: Raritan 7, Island Raritan 8, Dakota 11, Atane 
4, Mill Creek 1, Wocdbine 2, Montana 2, Vancouver 2,

This leaf resembles greatly the smaller of the two figures 
which are figured respectively by each of the above authors. 
* Dr. Hollick, who has seen a figure of this leaf, writes: ‘‘ Very close if 
not identical with Nelumbo Laramiensis.”
