SOME OTHER EXTINCT FORMS 



A S it is impossible within the limits of the 



present work to deal with each species that 



has become extinct during comparatively recent 



times, we may here make passing allusion to a few 



of the most notable instances, before dealing with a 



selection of those exotic species that are threatened 



with more or less speedy extirpation. As we have 



already shown, island species have suffered most ; 



and many of these are unfortunately surviving 



forms of avifaunas that have usually disappeared 



from other parts of the world, or always been 



excessively local. Many of these avine species 



have been lost before any detailed studies of their 



anatomy and habits have been made, many more 



are fast going, so that it behoves naturalists and 



anatomists to lose no time in making themselves 



acquainted with the various facts. In few other 



parts of the world has extirpation been more 



extended and disastrous than in the series of
