On Extinct and Vanishing Birds. 207 



Molokai the black Marno, Drepanorhamphus funereus, is 

 doubtless seriously threatened. 



In the West Indies the Amazon Parrots, Chrysotis augusta, 

 and Gh. bouqueti, from Dominica, and Ghrysotis versicolor, 

 from St. Lucia, are rapidly diminishing in numbers, and it 

 is not many years before they will also vanish. 



In conclusion, I have only to remark that the formidable 

 list I have brought before you proves very clearly that man is 

 the greatest enemy to all other living creatures ; but also I 

 think that it is evident that in very few cases is man the 

 final direct cause of the extermination of a species, but he is 

 still indirectly guilty in most cases, for the introduction of 

 vermin and animals of prey, and creatures foreign to the 

 country, generally finishes what man himself has begun. 

 A few of the foregoing species have died out from natural 

 causes, and I think it would be of scientific value if, in the 

 case of species not yet quite gone, some investigations into 

 these causes could be inaugurated. 



The accompanying tables will give concisely the various 

 species under the categories they belong to. I also have 

 appended a list of the specimens exhibited, and it only 

 remains for me to thank those who have lent me specimens 

 for exhibition, namely, Dr. Scharff, Dr. H. O. Forbes, Pro- 

 fessor Dr. Lampert, Count Berlepsch, and Professor Dr. A. 

 König, who lent me the Aestrelata jamaicensis, the Ara 

 tricolor, Necropsar legnati, and the Dromaeus ater, the Ballus 

 miilleri, 2 of the 3 Loxops ruf a, and one of the 3 Great Auks, 

 Alca impennis. With these 8 exceptions all the specimens 

 exhibited are the property of the Tring Museum.
