The Ornithological portion of this work occupies from page 

 18 to page 43, and is a reprint, with alterations, of the author's 

 paper published in this Journal (Ibis, 1866, pp. 88 et seq.). 

 Fringilla moreleti is here considered a synonym of F. tintillon ; 

 and Serinus hortulanus of the former paper is now identified 

 with the Wild Canary, S. canurius. A table shows the distri- 

 bution of Azorean birds with reference to the other Atlantic 

 Islands and Europe. At the end of the volume will be found 

 some general remarks stating the author's views as to the mode 

 in which these islands have been peopled with organic life, which 

 are of a suggestive character, and of interest to all occupied with 

 similar phases of the more speculative branch of our science.
