ME. R. B. SHARPE OK THE BIRDS OT" NEW GUIKEA. 405 



Contributions to the Ornithology of New Gruinea. ByE. Bowdler 

 Sharpe, F.L.S. — Part IX. On further Collections made by 

 Mr. A. Goldie in the Astrolabe Mountains. 



[Eead 17tli April, 1884.] 

 It is now some time ago since Messrs. Salvin and Grodman 

 showed me a collection of birds forwarded to them by Mr. Groldie, 

 but pressure of official work at the British Museum during the

 of the birds have passed into the national collection, and three of 

 these possess more than ordinary interest.
