E. W. Binney, F.R.S., V.P., exhibited a gigantic tooth of 
a fossil shark found in making the railway between Seville 
and Cordova in Spain. The age of the deposit in which it 
was found is not clearly ascertained, but it is probably 
Older Pleiocene. It is the largest that he ever heard of. 
Neither the very large specimen in the Hunterian Museum, 
London, from Malta, nor any in the numerous public mu- 
seums or private collections in England, equal that shown. 
Its dimensions are 6J inches in perpendicur height and 4J 
inches in breadth, and 10 inches in girth at its base. It 
is in a most beautiful state of preservation, nearly as per- 
fect as it was in the living fish, and probably belonged to 
Cavckarias vulgaris or some allied species.
