I I AYING lately had occasion to arrange the Lias fossils in the 

 -'-^ Bristol Museum, we observed a number from Mungar, 

 which can scarcely hitherto have been referred to their proper 

 horizon. The set of Mungar fossils in the Museum was collected 

 by the late Mr. S. Stutchbury, who placed them all in the 

 Middle Lias, an arrangement which has been endorsed 

 apparently, by subsequent curators. Some of them were left 

 undetermined, and, indeed, otherwise it would have been surely 

 seen that it was a question of other beds besides the Middle Lias. 

 Taking the Ammonites only, we have the following species in 

 the collection : — A. Johistoni, Co7iyheari, Sauzeanus, Jamesoniy 

 Maugenesti, ilex, hrevispina. The latter foui" of these are certainly 

 Middle Lias species, but the others are indubitably L. Lias forms^
