Six specimens and a nestling collected on Mount Kenepai, • 

 six on Mount Liang Koeboeng, one near Poelau on the 

 Sibau River and three specimens on the Upper Mahakkam. — 

 Iris dark brown, bill black, lower mandible horny blue, 

 feet flesh-color. The specimen from Poelau has the quills 

 and tail-feathers broadly edged with rufous, which pecu- 

 liarity is due to its immaturity. 



In my above cited note I have already pointed to the 

 difierence in color, probably due to the different localities, 

 of this species. Having no sufficient material, especially 

 from the Malay Peninsula and Sumatra, at my disposal, 

 I cannot tell about the specific value of these differences, 

 but I may be allowed to observe that our two Sumatran 

 specimens have their upper surface browner than all our 

 Bornean birds. Strange enough, there is no difference in 

 coloration amongst my 13 specimens from different loca- 

 lities, though both sexes are represented. Ail, except the 

 above mentioned immature bird from Poelau, have the 

 upper surface, with inclusion of the crown, olive, becoming 

 more brown on rump and upper tail-coverts, while the 

 tail-feathers are earthy brown and edged with rufous brown 

 towards the base. From these the Sumatran specimens in 

 the Leyden Museum differ in having the whole upper sur- 

 face more ruddy brown and the tail-feathers entirely rufous. 

 If all our Bornean specimens would be alike those men- 

 tioned above, they could be easily distinguished ; there are,
