Drawer 123. Hippurite limestone of cape Passero, interstratified with vol- 

 canic tuff ; and tertiary limestones of the Val de Noto, alter- 

 nating with antient lavas. 



For a description of this fossil see Owen's Palaeontology, p. 64. As it is usually found in 

 the chalk, it would seem that the volcanic rocks of the Val di Noto began to be formed in 

 the cretaceous period, although they continued to be erupted during the tertiary epoch, as 

 shown by the shells present in the strata which alternate with volcanic materials in other 

 parts of this district. See also Geological Transactions, ii. 277.
