In ' The Ibis ' for April of last year (p. 338) will be 

 found some account of Mr. Stresemann^s expedition to the 

 Dutch Indies^ and he is now engaged in working out the 

 results at Tring. In the first of the papers now noticed he

 Macropygia ruficeps, Alcedo ispida, Thriponax javensis, and 

 Centropus sinensis, among which many novelties are de-

 months in 1898, and whose collections were described by

 53, making 149 in all. Doherty only collected on the
