DEFINITIONS

PACHYCEPHALA
(Pachycephalidae; Ϯ Golden Whistler P. pectoralis) Gr. παχυς pakhus  large, thick; κεφαλη kephalē  head; from the appearance of their large rounded heads the Indomalayan and Australasian whistlers were formerly known as 'thickheads'; "The interval betweeen the present groups and those of the Pari, where we entered on the family [Pipridæ], appears to be filled up by a race of birds peculiar to New Holland, and hitherto uncharacterized, of which the Muscicapa pectoralis, Lath. is the type*. These, uniting many external characters, at least, both of the Berry-Eaters and Flycatchers, exhibit also in general appearance a considerable resemblance to the Pari, and will be found, I conjecture, to be the connecting bond between all these groups.  ...  * Mr. Swainson has lately formed this group into a genus by the name of Pachycephala.  Nov. 1824." (Vigors 1825); "Genus. PACHYCEPHALA*. Swains. MSS.  ... Caput tumidiusculum.  ...  In their general appearance some of the species exhibit a resemblance to the birds of the genus Procnias, Ill., while by the puffed-out appearance of the feathers about the head, we trace an approximation to some of the Linnean Pari.  ...  * παχυς crassus, and κεφαλη caput" (Vigors & Horsfield 1827). 
Var. Pachycephalus.

implicata
L. implicatus  united  < implicare  to entwine.
• "Hypocnemis cantator implicata, new subspecies.  ...  One of the interesting things about the present form is the apparent regularity of its variation in the direction of the adjacent conspecies as it approaches their ranges.  It is not, however, an intermediate between striata and peruviana in its general appearance so much as between striata and cantator." (J. Zimmer 1932) (subsp. Hypocnemis striata).
• "Pachycephala implicata, new species.  ...  This bird, quite overlooked hitherto in spite of former collections made on Guadalcanar, is a very aberrant Pachycephala.  ...  This peculiar new form is nearest to Pachycephala pectoralis dahli Reichenow, from the Bismarck Archipelago" (Hartert 1929) (Pachycephala).
