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. Meyer 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, repre- 

 senting 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 was 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 1 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), 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 are better defined and more 

 conspicuous. The five middle pairs of rectrices have four broad black bands, besides
