One specimen (junior), which is exactly similar to the 

 five from Celebes , described by Prof. Schlegel under the 

 name of A. Lansbergei (1. c). A.11 these six specimens are 

 apparently younger birds, the dark parts showing more or 

 less that kind of fulvous tinge which is so peculiar to the 

 young stage of those species whose dark parts become slaty 

 blue when adult. The white feathers on the edge of the 

 wing are another indication of the young stage of these 

 birds, and also is the want of the lengthened feathers on 

 neck , chest and rump , which are so very characteristical to 

 adult birds of this family. The upper surface and sides of 

 the head, and the hiud neck are strongly tinged with ashy 

 gray, and in two specimens the somewhat lengthened occi- 

 pital feathers are intermixed with some black ones, which 

 make it evident that in a more advanced stage the whole 

 upper surface of the head will change into black. 



As the measurements of the mentioned birds are absolu- 

 tely the same as in A. picata, and the lower surface in the 

 young stage of this latter species is stated to be white 

 (Gould , 1. c), I feel quite sure that A. aruensis is nothing 

 but a young stage of A. picata.
