the works of Horsfield, Temminck, Bonaparte, Schlegel, and 

 other authorities, and arranged on the system of Prof. 

 SchlegeFs ' Dierentuin." 404 species are enumerated, of 

 which the author claims 14 as due to his explorations of the 

 neighbourhood of Batavia and Mount Salak. Of these 14, 

 one, Brachypteryx salacensis, is stated to be new, but no 

 description is given. We are glad to be told that Mr. Vor- 

 derman has in preparation a monograph on the birds of 

 Java, on the same plan as Salvadori's excellent work on the 

 birds of Borneo.
