it is very doubtful if they all belong in the genus.* Schimper, in 
his Traité de Paléontologie Végétale, 3: 95, says in regard to W. 
Casparianum Heer and N. nympheoidea Ettingsh.: “I do not think 
that the true position of these two last fossils is in the genus Ne- 
lumbium,’ but further than this I would not wish to carry the 
criticism without having had an opportunity to examine the 
material upon which the names were based. It is, however, pet- 
tinent perhaps in this place to call attention to the leaf which was 
NELUMBO LARAMIENSIS HOLLICK.

Roy. Soc. Canada, 3, Sec. 4: 15 (1885)) from the Belly River be . 
of British Columbia, representing a geological horizon practically ; 
equivalent to our Laramie. From the description and ane: 
given by Dawson it appears to resemble MVelumbo more closely
