These memoirs are all supplementary to Dr. Hartert's 

 former papers on the Birds of the South-west Islands, in 

 the Moluccas (Nov. Zool. 1904, p. 174, and 1906, p. 288). 

 Sermatta had not been previously visited, but has now pro- 

 duced examples of 45 species, none of which are peculiar. 

 Six additions are made to the Avifauna of Babber, and eight 

 to that of Luang, but none of them are peculiar. 



The small island of Marsela alone remains unexplored.

This important and finely illustrated work is a welcome 

 contribution to Ornithology, and comes at a time when it is 

 possible to sum up, with a fair chance of completeness, the 

 information to be gathered from the writings of niany 

 former explorers. The author, moreover, has visited the 

 Spitsbergen group on no less than three occasions, and has 

 thoroughly explored a large extent of territory in company 

 with several friends, of whom Baron Geyr von Schweppen- 

 burg and Dr. Otto le Roi may be more particularly 

 mentioned. ., 



The ornithological part of the book consists of two main 

 portions, the first being devoted to a general account of the 

 journeys, including Norway, with a full descrij)tion of the 

 country and its fauna by the author himself ; and the 

 second containing articles on the diff'erent species by 

 Dr. le Roi, in addition to an Ornithological Bibliography of
