Mr. Annitage also drew attention to the " silt-jetties " 

 rapidly forming at the mouth of the Avon River, and ex- 

 tending some distance into Lake Wellington, indicating that 

 considerable erosion is going on in the valley of the Avon. 



Mr. P. R. H. St. John remarked that the Kookaburra, or 

 Laughing Jackass, Da eel o gigas, was creating great destruction 

 among the nestling birds in the Melbourne Botanic Gardens, 

 and was not deserving of any protection. 



The chairman related an instance of a Magpie-Lark, or Pied

Corrections. — In the report of the April meeting, on page 2, 

 " Gryllotalpa coarcta" should read '' Gryllotalpa coarctata." In 

 the note on " Bodies Resembling Australites," the words '• are 

 generally conceded to be of volcanic origin " should read " are 

 by some supposed to be of volcanic origin."
