prolific in interesting cryptogams. In spite of that, several new 

 species and even a new and well marked genus are the results, clearly- 

 indicating, how much still remains to be done in Indian Phycology. 

 Zollinger s' and E. v. Martens' collections of Algae in the 

 Indian Archipelago are far the richest as yet made in those coun- 

 tries, but in looking over the following short list, it can easily be 

 observed that a good number of species, although not new to science, 

 still are very interesting in a phyto-geographical point of view, as 

 they were never before found by former botanists in those localities.
