ALGAE. 



As yet the study of the classes of true tballophytes, embracing the 

 plants generally described as algae, has received scarcely any attention 

 in Alabama. The sandy shoals and the sandy shores washed by the 

 waves along the eastern Gulf coast from Louisiana to northwestern 

 Florida are unproductive of algae, and only a few species of the higher 

 forms nod their home on our shore. Witli the exception of Characeae 

 and Lemaneaceae, it has been necessary to omit the so-called fresh- 

 water algae, as we know too little of them at present. 



The successful efforts of Dr. George H. Taylor and the Messrs. K. M. 

 Cunningham and William McNeil in cleansing samples of the mud of 

 Mobile Bay obtained from the almost fresh water of the estuary 

 of Mobile Eiver, the more or less brackish water of the upper bay 

 and the brine of the lower bay have brought to light a considerable 

 number of interesting forms of the diatom family, which are here placed 

 on record. The work of these skillful and diligent collectors has been 

 spoken of by Hon. J. D. Cox, LL. D., of Cincinnati, in the American 

 Monthly Microscopic Journal. 1 At the same time the following list has 

 been furnished by Mr. Cox, to whom the cleansed material was at the 

 time submitted for examination. The generic and specific names have 

 been revised to conform with De Toni's Sylloge Algarum.
