^Almost certainly identical with M. alabamensis Herrick. 
In all cases “Asia” means Ceylon, Siam, Sumatra, or oilier 
part of tropical Asia. All of these species, therefore, belong 
to tropical or subtropical waters. To the list may be added 
Pseudosida bident at a, which is apparently identical with 
Parasida variabilis Daday. It appears, therefore, that 21 
tropical species of Cladocera are found along our southern 
coast, only one of which extends its range to the north, so far 
as now known. All but one of these species are found in 
South America, and this will probably be discovered there; 
since it would be singular if this should prove to be present in 
the United States and Ceylon and not in South America. 
No doubt a more complete study of southern Cladocera will 
show many more forms common to this country and South 
America.
