small a fragment, however, for rigid determination. It rep- 

 resents a small-leaved species with leaves apparently about 

 the same size as those of JV^eltimbo Laraniiensis Hollick (/. c. 

 f. 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 N. Laramiensis.*' Nelumho inteTmedia,\ 

 of the Montana formation, is of about the same size, but has 

 twelve or thirteen weak primary veins. Nclumbo Dazvsoni 

 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 Nelumhium Saskachtiensis, of 

 similar size and with only seven primaries.

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 Neluinbo Laratnieusis."
