Pachycephala pectoralis bougainvillei Mayr

Pachycephala pectoralis bougainvillei Mayr, 1932a: 10 (Bougainville Island, Solomon Islands).

Now Pachycephala orioloides bougainvillei Mayr, 1932 . See Galbraith, 1956: 197, Schodde, 1977: 75, Coates, 1990: 211, Mayr and Diamond,

2001: 395, Dickinson, 2003: 477, and Boles, 2007: 421.

HOLOTYPE: AMNH 222852 , adult female, collected on Bougainville Island , North Solomons Province, Papua New Guinea, on 26 January 1928, by Frederick P. Drowne (no. 533), on the Whitney South Sea Expedition.

COMMENTS: Mayr cited the AMNH number of the holotype in the original description and listed 36 specimens of bougainvillei, including the type, from Bougainville, Shortland, and Buka islands ; there are, however, a total of 37 specimens. The 36 paratypes are: AMNH 219973–219976 , 222821–222842 , 222856 , 222859 , 222860 , 222997–222999 , and 223001–223004. AMNH 222822 and AMNH 222830 were exchanged to ZMB in 1936 .

On Bougainville in January 1928, the Whitney Expedition personnel went inland from Kieta and set up a base camp near the village of Kupei, 06.19S, 155.33E (USBGN, 1956d), at about 2300 ft. Hamlin wrote (vol. S, unpublished journal, archives, Department of Ornithology, AMNH) that the ‘‘Black-bibbed Thickhead’’ occurred from the shore to 3000 ft, where it was replaced by the ‘‘Mountain Thickhead,’’ P. implicata .

Galbraith (1956: 197), Mayr and Diamond (2001: 395), and Boles, 2007: 421 considered bougainvillei a valid subspecies of P. pectoralis ; Schodde (1977: 75) and Coates (1990: 211) considered bougainvillei a synomym of P. pectoralis orioloides ; Dickinson (2003: 477) recognized bougainvillei as a subspecies of the species P. orioloides .
