Pachycephala implicata richardsi Mayr

Pachycephala implicata richardsi Mayr, 1932a: 3 (Bougainville Island, Solomon Islands).

Now Pachycephala implicata richardsi Mayr, 1932 . See Mayr and Diamond, 2001: 395, and Boles, 2007: 419.

HOLOTYPE: AMNH 226339 , adult male, collected on Bougainville Island , North Solomons Province , Papua New Guinea, on 5 January 1928, by Hannibal Hamlin (no. 138) on the Whitney South Sea Expedition.

COMMENTS: The AMNH number of the holotype was cited in the original description and the range of richardsi given as ‘‘the mountains of Bougainville Island.’’ The following specimens are paratypes: AMNH 222816–222820 , 222843–222851 , 222853– 222855 , 222857 , 222858 , 226331–226338 , 226340–226344 , 226344 a, and 226345– 226361. Of these, AMNH 226331 was exchanged to ANSP and AMNH 226334 was exchanged to ZMB in July 1936. AMNH 226359 was marked in the catalog as exchanged to Cleveland on 6 January 1932 ; however, that specimen is in the collection and I failed to find AMNH 226357 . It is possible that the wrong specimen was marked. Other cataloged specimens that I failed to find in the collection are: AMNH 222845 , 222849 , 226341 , 226351 , and 226353 .

On 5 January 1928, Whitney Expedition personnel were at Kupei, 2300 ft, 06.19S, 155.33E (USBGN, 1956d), inland from Kieta on Bougainville Island. Hamlin (unpublished journal, vol. S, archives, Department of Ornithology, AMNH) noted that they collected between 1500 and 5200 ft and that the ‘‘Black-bib thickhead was replaced by the drabber mountain variety.’’
