206 Evans: THE HEPATICAE OF THE BAHAMA ISLANDS 
out the group, and that others still await discovery. The col- 
lections already made, however, show clearly the general char- 
acteristics of the hepatic flora. 
The present paper includes a full report on the various speci- 
mens studied by the writer. Under each species the local distri- 
bution in the archipelago is given, together with notes on the 
general distribution. New or otherwise noteworthy species are 
treated more fully than the others and, in conclusion, the relation- 
ships of the Bahamian Hepaticae to those of neighboring regions 
are briefly discussed. Since many of the Lejeuneae listed have 
recently been studied critically by the writer, references are given 
to papers in which descriptions of such species may be found. 
No attempt is made, however, to treat the synonymy at length.
