THE BIRDS

(Plates 13—15). 



When writing my introduction to Dr. Jentink's treatise 

 on the Mammals collected during my sojourn in Borneo 

 (N. L. M. XIX (1897), pp. 1—26), I bad no idea that the 

 publication of the present paper, which at that time was 

 nearly ready for the press, would have to undergo such a 

 long delay. But the duties of my new position as Director 

 of the Zoological Garden at Rotterdam absorbed so much 

 of my time that I could not think much about finishing 

 my manuscript. And even now I am, for want of time, 

 unable to do what I originally had proposed myself to 

 do, i. e. to give a critical review of the birds of Borneo, 

 but must content myself with an enumeration of the spe- 

 cies obtained by myself and my companions, especially by 

 my assistant Mr. Max Moret, who, after my return to 

 Europe, made a small collection of birds in the surround- 

 ings of Pontianak near the west coast, and of Dr. A. W. 

 Nieuwenhuis ^), who, from May 1896 to May 1897 and

 of Dr. Jentink's on the Mammals collected on this second expedition by Dr. 

 Nieuwenhuis (N. L. M. XX (1898), p. 113).
