 •I figs. 

 Bere is given a corrected list of the fossils 

 found on St. Helens Island, showing that two 

 distinct faunas occur there, one, the Helder- 

 bergian, older than the agglomerate, and 

 another, from a block in the agglomerate, of 

 Middle Devonian age. The Helderbergiau 

 fauna is not mixed up with Silurian nor 

 Middle Devonian fossils, as described by pre- 

 vious students.

 Introductory remarks on the relation of 



Biology to Physiography, by C. W. Hayes 



and Mr. R. Campbell, are included in 



this paper. 

 The conclusion is reached from the evi- 

 dence of the Unionidse that the Tennessee 

 River formerly flowed into the Coosa River 

 and into theGulf of Mexico through the Ala- 

 hama system. Many of the species which are 

 ahundant in the Tennessee system and that 

 donotoccurintheLowerMississippiare found 

 slightly changed in the Alabama and its 

 tributaries. A large number of species of the 

 genus Pleurdbema of the Tennessee drainage 

 are closely related to those of the Alabama 

 drainage. There is also evidence, from the 

 present distribution of the CJnionidse, point-
