Now Pachycephala implicata implicata Hartert, 1929 . See Mayr, 1932a: 2 , Mayr and Diamond, 2001: 395 , and Boles, 2007: 419 . LECTOTYPE : AMNH 218045 , immature male, collected on Guadalcanal ( 5 Guadalcanar) Island , Solomon Islands , on 25 July 1927 , by Rollo H. Beck on the Whitney South Sea Expedition (no. 27052). COMMENTS: When this species was originally described, part of the description was omitted and the listing of the type of Pachycepala pectoralis whitneyi , the next form discussed by Hartert, was placed so that it appeared to refer to the type of implicata , as noted by Mayr (1932a: 2) . Thus, no type was designated for P. implicata , although Hartert listed his four specimens , referring to them by their Whitney Expedition field number. Hartert, however, did write ‘‘ implicata ’’ and ‘‘Type’’ on the label of the lectotype and color the end of the label red. Mayr (1932a: 2) , noting that Hartert had intended this specimen as his type, designated AMNH 218045 as the lectotype of P. implicata . Hartert had considered the specimen an almost adult male, but a fully adult male specimen received after the publication of Hartert’s description showed that the lectotype was an immature male. Mayr (1932a: 2) then described the adult male, but Hartert’s type series comprises only the four specimens that he saw. Paratypes are: AMNH 218044 (Whitney no. 26855), immature male, collected 22 July 1927 ; AMNH 218046 (27055), immature (sexed as male, but perhaps female), 27 July 1927 ; and AMNH 218048 (27053), female, 25 July 1927 . On 14 July 1927 , the expedition vessel, France , anchored in a bay near Cape Hunter and the collecting party went eastward to the ‘‘big river,’’ spending 20–28 July inland, ascending to over 4000 ft. The river is the Itina (sometimes spelled Ithina) River, 09.48S , 159.51E (USBGN, 1974).
