Now Pachycephala olivacea olivacea Vigors and Horsfield, 1827 . See Schodde and Mason, 1999: 433–435 , Boles, 2007: 412 , Jønsson et al., 2008 , and Dumbacher et al., 2008 . HOLOTYPE : AMNH 659405 , female, collected at Olinda , 37.51S , 145.22E ( USBGN , 1957), Victoria , Australia , on 11 May 1907 , by Thomas H. Tregellas. From the Mathews Collection (no. 4908) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description. He cataloged three Tregellas specimens at the same time, but I consider only one of the other two specimens a paratype : AMNH 659404 (Mathews no. 4909), male, collected 9 May 1908 at Olinda. A second paratype is AMNH 659427 (Mathews no. 2726), an unsexed specimen collected in Gippsland, Victoria , on 17 July 1886 , and received from Ashby. AMNH 659424 , male juvenile, collected 28 December 1908 at Sassafras by Tregellas may also be a paratype ; its data do not match the data in Mathews’ catalog for the third specimen and I did not find it elsewhere in his catalog, but Mathews frequently did not catalog juvenile specimens. The third specimen, opposite catalog no. 4910, is listed as a male collected on 20 December 1908 and the locality ‘‘ Olinda’ ’ is dittoed from the other two specimens . Probably , a specimen with data matching this entry was once in Mathews’ collection and was exchanged to persons unknown ; if found, it is a paratype of tregellasi . AMNH 659406 and 659407 (no. 11689, only one entry), collected on 6 October 1910 on Mt. Dandenong were collected before he described tregellasi but not cataloged by Mathews until November 1912 , long after the description was published. The following four specimens were not found entered in Mathews’ catalog and are not considered paratypes : AMNH 659408 , an undated specimen collected in the Dandenong Range by Chandler ; AMNH 659423 , male, collected 24 November 1911 at Lorne by J. Ross ; AMNH 659425 and AMNH 659426 , collected at Lang Lang , but undated .
