Repoi't on the Extinct Birds of the Mascarene Islands. By a Com- 

 mittee consisting 0/ Professor A. Newton, Rev. H. B. Tristram, 

 and Dr. Sclater. 



^UjrcsT immediately after the appointment of the Committee, intelligence was 

 received in England of the very important discovery by Mr. George Clark, of 

 Mahebourg, in Mauritius, of a large deposit of bones of the true Dodo {Dklus 

 hieptus), in a marsh known as the « Mare aux Songcs,' an accoimt of which 

 that gentleman has published in 'The Ibis' Magazine for April 1866. 

 Several fine series of these bones having been sent to England, some were 

 purchased by the Trustees of the British Museum, and formed the subject 

 of a memoir " On the Osteology of the Dodo," read by Professor Owen at a 

 meeting oi the Zoological Society of London, 9th January, 1866. This 

 memoir is understood to be nearly ready for publication, and will appear, 

 copiously illustrated, in the ' Transactions ' of that Society. Some other tine 

 series of these bones have, by the liberality of Mr. Clark, passed into the 

 possession of one of the members of your Committee ; and a portion of them 

 is now exhibited. Several smaller series of bones have likewise been vari- 

 ously distributed by sale or gift both in England and on the Continent, so that 

 numerous Museums (one of these smaller series forms the subject of some 

 " Remarques " communicated to the Academv of Sciences of Paris, 23rd April,
