1872.] ON THE BIRDS OF CELEBES. 207 



Appendix to a List of Birds knoivn to inhabit the Island of Celebes. By Arthur, Viscount '^'^- '^'- ^; '^'i'- 

 Walden, F.R.S., President of the Society. [From the ' Transactions of the Zoological 

 Society,' vol. viii. part ii. May 1872, Plates XI. to XIII. in orig.] 



I. Additional Observations on the Birds included in the 'previous List. 



While the List of Celebean Birds contained in the preceding pages was passing through the 

 press the island of Celebes was being visited and its zoology investigated by a most indefatigable 

 collector and naturalist, Dr. Bernhard Meyer. With the greatest liberality Dr. INIeyer has 

 permitted me to examine all the birds collected by him in Celebes ; and I avail myself of this 

 opportunity to thank him for his courtesy. The additional materials thus placed at my disposal 

 have enabled me to add to the list several species which had not previously been known to 

 inhabit Celebes, as well as a few more which were altogether new to science. The considerable 

 number of examples, representing the rarer species, collected by Dr. Meyer, has also rendered it 

 possible and desirable to add some supplementary observations. The greater part of the collection 

 was made in North Celebes, and consequently on old ground ; yet Dr. Meyer has added twelve 

 species new to the island, and at least four of which were previously undescribed. In the Togian 

 islands a small collection Avas likewise made, showing that these islands, as we might have 

 naturally supposed, possess a generally Celebean ornis ; yet, among the small number of species 

 thus obtained, two * were new to science, and have not as yet been discovered on the mainland 

 of Celebes.

Three stages of immature plumage, hitherto undescribed, are represented by three individuals 

 obtained in North Celebes. 



One, a male (PI. XL in orig.), has the head dark brown, mixed with rufous. The back, wings, 

 and tail are bright rufous. The nuchal and dorsal feathers are centred with dark brown. The 

 wing-coverts have each a black subterminal drop. The secondary quills are crossed by five 

 distinct black bands. The basal halves of the primaries are banded with brown and pale 

 rufous alternating; the terminal halves are light brown, obscurely banded with dark brown, 

 rufous replacing the light brown on the outer webs. On the under surface of the quills the dark 

 brown bands arc better defined and more conspicuous. The five middle pairs of rectrices have fonr 

 broad black bands, besides an obscure brown band at the root of the feathers. The outer pair Tr. Z. S. viii. 

 have seven bands. The plumage of the under surface of the body is fulvous, each feather with ^' 

 a bold brown longitudinal central stripe. The under tail- and shoulder-coverts are unsjjotted 

 fulvous. The middle toe is very long ; and the tail is conspicuously forked. 



The second example is of a young female, much resembling the male above described, but 

 having bold brown drops on the under shoulder-coverts and axillaries, and the general colouring
