Pachycephala pectoralis balim Rand

Pachycephala pectoralis balim Rand, 1940: 8 (Balim River, altitude 1600 meters; Snow Mts., Netherland [sic] New Guinea).

Now Pachycephala pectoralis balim Rand, 1940 . See Sibley and Monroe, 1990: 460, Schodde and Mason, 1999: 443, and Boles, 2007: 421.

HOLOTYPE: AMNH 305652 , female, collected on the Baliem ( 5 Balim ) River , 1600 meters, 04.25S, 138.59E ( USBGN, 1982), Maoke ( 5 Snow ) Mountains , Papua Province ( 5 Netherlands New Guinea), Indonesia, on 12 December 1938, by R. Archbold, A.L. Rand, and W.B. Richardson on the 1938–1939 Archbold Expedition to New Guinea (no. 8631).

COMMENTS: In the original description, the AMNH number of the holotype and measurements for 14 males and eight females were given. The type series from the Baliem and Ibele ( 5 Bele, as on label) rivers comprised 16 males, eight females (including the holotype), one sex?, and one female nestling ; the 25 paratypes are AMNH 341477–341501 . The 1938–1939 expedition was a joint expedition with the Netherlands New Guinea government, known as the Indisch-Amerikaansche Expeditie, and a share of the specimens was sent to MZB in May 1957, including three specimens of this form: AMNH 341480 , 341486 , and 341494. AMNH 341492 and 341499 were exchanged to FMNH in the early 1960s .

Sibley and Monroe (1990: 460) suggested that balim might be considered a species separate from P. pectoralis , but most authors have retained it as a subspecies, e.g. Beehler and Finch (1985: 43), Schodde and Mason (1999: 443), Dickinson (2003: 476), and Boles (2007: 421).
