ABSTRACT OF THE PROCEEDINGS 



OF THE 



ZOOLOGICAL SOCIETY OF LONDON, 



April 9tli, 1918. 



Dr. A. Smith Woodward, F.R.S., Vice-President, 

 in the Chair. 



The Minutes of the last Scientific Meeting were confirmed. 



The Secretary read a Report on the Additions to the 

 Menagerie in the month of March, 1918. 



Miss Cheesman, Acting Curator of Insects, exhibited and 

 made remarks on examples of the East African Plant-bug, 

 Itymcea nigrocincta, sent from the Nairobi Museum. 



Dr. A. Smith Woodward, F.R.S., Y.P.Z.S., exhibited fossil 

 rostral teeth of the Sawfishes Eophristis and Fristis, and ref ei-red 

 to the progressive changes in the rostral teeth of the Pristidss 

 during geological time. 



Mr, G. A. BouLENGER, F.R.S., exhibited the head of an 

 example of HydroGyon goliath, Blgi'-j from the Congo, a fish 

 attaining the length of four feet. The object of the exhibition 

 was to show the enormous shark-like teeth, to which special 

 interest attaches, owing to a similarity, recently pointed out by 

 Dr. Eastman, to fossil teeth occurring in the Upper Cretaceous, 

 which would appear to indicate the existence of Characinidfe in 

 that geological epoch, a range in time which Mr. Boulenger had 

 predicted as probable thirteen years ago.
