ALGAE. 
As yet the study of the classes of true thallophytes, 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 fivd their home on our shore. With 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 MeNeil in cleansing samples of the mud of 
Mobile Bay obtained from the almost fresh water of the estuary 
of Mobile River, the more or Jess 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.'! 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
