the present day, keep up the tradition by styling its inhabitants

Notice on some species of birds now extinct , which are found 
represejited in the collections of the Museum of Natural 
History (of Paris). By Alph. Milne-Edwards and Ed. 
Oustalet. Paris: Imprimerie Nationale, 1893. Extract. 
The rich collections of the Natural History Museum include 
some specimens of birds of great value, to which we think atten¬ 
tion should be drawn. These specimens in fact belong to species 
which have disappeared within historic times (some indeed at 
quite a recent date), and of which many great museums do not 
even possess representatives. It is the duty of scientific estab¬ 
lishments, which have the good fortune to contain such rare 
objects in their collections, not only to try to guarantee them 
against every cause of destruction, but, besides, to make them 
known as completely as possible by descriptions and figures, in 
order that should these examples, by any accident, happen to be 
annihilated, their characters and their zoological affinities could 
still be appreciated by the naturalists of the future. It is this 
which has prompted us to publish this work, in which will be 
found descriptions more detailed, and figures more exact, than any 
which have been published to the present day; and in addition, 
a certain amount of information, hitherto unpublished, which we 
have been able to collect, and which permits us to lay down pre¬ 
cisely the place of origin, or to throw light on some hitherto 
obscure points in the history of five extinct species, viz., the 
Mascarin Parrot (Mascarinus Duboisi ), the Huppe du Cap (Fregi- 
lupus varius), the Crested Dove (Alectroenas nitidissima ), the 
Labrador Duck (Camptolcemus labradorius ), and the Black Emeu 
(Dromaius aier). We also give some details of the Great
