10 Proceedings of the Asiatic Society. [Jan. 



botanists, meanwhile more than 1000 species of Musci and Hepaticce 

 have become known from British India alone. With regard to 

 Indian seaweeds, Prof. v. Martens' work "Die Tange der 

 Prenssischen Expedition nach Ost-Asien," contains almost all that 

 is known about them. In a very cursory exploration of Bengal 

 I have obtained about 40 to 50 species of fresh- and brackwater- 

 Algre, but this number is only a fraction of what really can be 

 found in a country like Lower Bengal, in the flora of which the 

 richness of water plants is the most characteristic feature. As my 

 researches into the flora of the cryptogamic plants of Bengal, and 

 of India generally, are now in progress, I defer for a future op- 

 portunity the communication to the Society of a systematical list, 

 containing all that is known of Bengal Algse.
