There are several sub-adult specimens from Koelawi and a young 

 bird not long from the nest from Rano Lindoe, March 4. The young 

 resembles the adult but is duller above and much lighter yellow 

 below. 



As this species has not been reported from north-central Celebes 

 before, the measurements of the series in the United States National 

 Museum are given below : 



171. ZOSTEROPS ATRIFRONS ATRIFRONS Wallace. 



A fine series from the following localities: Paleleh River, August 

 18, 1914; Toli Toli, December 4-19, 1914; Kampa, February 14, 

 1915; Ayermadidi, April 1-2, 1916; Manembo Nembo, June 22, 

 1916 ; Toemaratas, July 3-9, 1916. 



The birds from Toemaratas are whiter on the breast and the 

 yellow of the throats are deeper than the rest of the series, but this 

 is probably due to the different season of the year in which they 

 were collected. Specimens from the mountainous central part of 

 the island are larger and duller than even winter specimens from 

 the north and these I have separated below. 



172. ZOSTEROPS ATRIFRONS SURDA RUey.o" 



A good series from the following localities: Koelawi, February 

 23, 1917; Rano Lindoe, March 5-24, 1917; Doda, Besoa, October 

 27, 1917; Toewo Mountain, Besoa, October 28-November 4, 1917.
