Ten of these are from Europe and three from America. It is 
doubtful if they should all be retained in the genus, but most of 
them are too well defined to admit of any doubt as to their botan- 
ical affinities. 
The new species here described was recently brought to light 
while examining a quantity of undetermined material collected in 
188384, at Carbonado, Wash., by Mr. Edward Lorrance, under 
the direction of the late Professor J.S. Newberry. The specimens 
include about fourteen individuals, perfect and fragmentary, and | 
upon some of them I found labels, in Professor Newberry’s hand- 
writing, with the name Salvinia elliptica, n. sp., which name I have 
retained. The best ones are figured in the accompanying plate, 
together with an enlargement to show the arrangement of the 
pits, and a figure of each of the other fossil species thus far de- 
scribed, for purposes of comparison. In this latter connection I 
wish to acknowledge my indebtedness to Professor Lester Fo 
Ward, of the United States Geological Survey, for references ay 
several species which I should have otherwise missed. ie
