brackets with my initials, I, therefore, am alone answerable. Diatomacece 

 and the greater number of Desrnidiacew are not represented, but I hope to have 

 an opportunity of collecting further materials for a more complete list than the 

 present one. The numbers between brackets and the letter " K." have reference 

 to my collection of Crypt. Cellulares. The seaweeds commonly eaten by the 

 Burmans, are Gigartina spinosa, G rev., (agar agar of the Malays), and Sph'iro- 

 coccus lichenoides, Ag., (Ceylon moss of commerce). These are usually called 

 by the Burmans Kyouk $u6n.
