I have not thought it necessary to change any of the above names to 

 correspond with those which I have adopted. It is necessary, however, to 

 mention that the genus Micrasterias of Ehrenberg is Pediastrum of Meyen, 

 Ralfs, &c., and of my lists, while the Euastrum of Ehrenberg is in part equiva- 

 lent to the Micrasterias of Agardh, Ralfs, &c ., whose names I have used.

Since this Memoir was in type I have received from Dr. W. C. Daniell, of 

 Savannah, Ga., several specimens of soil from his rice fields, ten miles above 

 Savannah. These prove to be exceedingly rich in the same species of marine 

 silicious Diatomaceae which occur in the soil of the plantations opposite 

 Savannah. One of Dr. Daniell's specimens appears to be almost entirely made 

 up of perfect shells of Coscinodiscus subtihs, Ehr.
