I. General Subject. 



The following is a general summary of some of the above papers, the contents 

 of which are not sufficiently important to merit special reference. Bassani ( 2 ) 

 and Sauvage ( 6 ) have not been seen by the recorder. Gaudry has published a 

 popular work on the animal kingdom in Geological times, containing notes and 

 many woodcuts of known extinct Fish. Kramberger-Gcrganovic describes 1 1 

 species as new all of which are referred to recent genera. A table is added giving 

 a complete list of the species and shewing in which formation they occur.
