IT have looked over our large material from the above 
mentioned localities again and I am only strengthened in 
my opinion, expressed in the above mentioned paper on 
Sumatran birds, that the Bornean birds should not be sepa- 
rated under the name of D. brachyphorus. 
Extract from Mr. von Berchtold’s field-notes: »Ich habe 
sehr oft Gelegenheit gehabt zu beobachten, dass diese Vogel, 
namentlich vor der Abenddimmerung, sobald sie paarweise 
ihr Nachtquartier bezogen haben, die vorbeifliegenden Raub- 
vogel unter heftigem Geschrei attaquiren und dieselben 
eine kurze Strecke verfolgen.” 
Laniidae. 
121. Hemipus obscurus.
