175. DIACEUM NEHRKORNI W. Blasius. 



Two males, Toemaratas, July 4, 8, 1916; one male, Rano Lindoe, 

 March 8, 1917; two males, Toewo Mountain, Besoa, October 29, 

 and November 3, 1917. 



All the above males have a median sooty black line within the area 

 of white of the abdomen, a feature not mentioned by Meyer and 

 Wiglesworth ^^ in their description, but as it is shown on the plate 

 the omission must be an inadvertence. 



The above series when compared with four males from Indrula- 

 man, south Celebes, kindly loaned me by J. H. Fleming, appear to be 

 lighter on the throats and foreneck; in size they are about the 

 same. The differences are too slight for separation by name, however. 



176. ACMONORHYNCHUS AUREOLIMBATUS (Wallace). 



A good series of both sexes and immature from : Paleleh River, 

 August 17-18, 1914; Kwala Besar, August 23-24, 1914; Soemalata, 

 September 4-7, 1914; Toli Toli, December 4-14, 1914; Tandjong 

 Penjoe, February 25-26, 1915; Likoepang, January 21, 1916; Goe- 

 noeng Lehio, Januarj^ 18, 1917; Rano Lindoe, March 5-23, 1917; 

 Gimpoe, August 3-September 1, 1917; Pinedapa, January 23, 1918. 



The birds from the north-central mountain country are duller 

 above and the yellow of the flanks is not so bright as in birds from 

 the north end of the island, but it is not advisable to separate them 

 at present.

 177. AETHOPYGA FLAVOSTRIATA (Wallace). 



Two adult males and three adult females, Toli Toli, December 2-9, 

 1914; one adult male, Tandjong Penjoe, February 26, 1915; one adult 

 male, Lindoe Trail, February 28, 1917 ; one adult male, Rano Lindoe, 

 March 25, 1917; one immature and two adult males and one adult 

 female, Gimpoe, August 2-24, 1917. 



The males from the central part of the island seem to have the 

 metallic crown more restricted, and the red of the back brighter 

 than northern specimens, but the series from the two localities are too 

 small to reach any definite conclusions. 



The young male taken at Gimpoe, August 11, is similar to the 

 adult female, but has more red on the back, the jugulum is tinged 

 with red, there is a small tuft of new red feathers in the center of 

 the chest, and it has acquired a single central tail-feather of the 

 adult plumage.
