One species Salvinia naians Hoffm., ranges from southern France 

 to India and northern China, and has been reported from several 

 locaHties in the United States. 



Continuing the enumeration of the fossil species it may be 

 noted that there is a rather well marked species in the Puget 

 group (upper Eocene or Oligocene) of Washington state; Miocene 

 species in Colombia, South America; and in Virginia in this 

 country. All of the remaining records are Old World, and 

 include Oligocene species in France, Saxony, and Bohemia; and 



Salvinia preauriculata Berry, n. sp.

Miocene occurrences in Germany, Bohemia, Switzerland, 

 Transylvania, Tonkin, China, and Japan. These have been re- 

 viewed recently in an important paper by Florin.* Some of 

 these species are said to show the dissected ventral leaves and 

 sporocarps, and Brabenec, in a paper which I have not seen,t 

 has described both micro- and mega-spores in Salvinia formosa 

 Heer from the Miocene of the Saaz basin in Bohemia, but it is 

 impossible to pass a critical judgment on a statement of this 

 sort without seeing the specimens upon which it was based.
