scapulars. A nestling with the pin-feathers just appearing was 

 taken in Java, March 25, another slightly older, July 9, and another 

 from the same island, completely feathered but with stubby tail, 

 and the remains of the nestling plumage still adhering to the 

 mesoptiles, July 8. The latter has the head and hind-neck tawny 

 streaked with blackish, the jugulum and foreneck with feathers 

 broadly streaked centrally with ochraceous-buff, the back mummy 

 brown with a cinnamon-rufous wash, and the outer primaries tipped 

 with hair-brown. In the next stage the back, scapulars, and tips 

 of the primaries are drab, the neck has become almost white with 

 onl}' a few buffy and dusky streaks, the top of head darker and the 

 dusky streaks more pronounced. After this stage the slaty dorsal 

 train begins to appear, the jugulum deepens, and the streakings on 

 the head and neck becomes more pronounced, and then the markings 

 on the head and neck gradually decrease again as the adult plumage 

 is assumed. Most of the foregoing remarks on the plumage of the 

 young are founded on Javan birds taken in spring or summer, in 

 conjunction with our Celebes birds. As a matter of fact, the Celebes 

 birds are browner on the back, not so slaty as the breeding Javan 

 i birds, but this is doubtless due to season. 



57. BUBULCUS IBIS COROMANDUS (Boddaert). 



Two males and two females, Rano Lindoe, March 8-13, 1917. 



These are often seen about wet rice fields and follow horses and water buffa- 

 loes to eat flies and ticks. — H. C. R. 



58. IXOBRYCHUS SINENSIS ASTROLOGUS Wetmore. 



One immature male, Toli Toli, December 10, 1914. 

 This specimen is too immature to show the characters of the race 

 and I am placing it here solely on geographic grounds. 



59. NANNOCNUS CINNAMOMEUS (Gmelin). 



One male, Toli Toli, December 16, 1914. 



In this specimen the wing-coverts are lighter than the back, about 

 the same as the sides of the neck. There is a specimen from Java 

 that is similar and one from Mindanao that has the wing-coverts 

 partially lightened, but in a second specimen from Java the wing- 

 coverts are as dark as the back or nearly so; from this I conclude it 

 is a matter of age. The Celebes bird is evidently fully adult as there 

 is no dark line down the center of the fore-neck. 



60. DUPETOR FLAVICOLLIS FLAVICOLUS (Latham). 



One male, Rano Lindoe, March 20, 1917.
