magnirostris. E. chloronotus lias also three subspecies. 
E. Icevig aster is restricted to the north-west and Northern 
Territory west of the Roper River, cant at or, mould , and 
mastersi being now considered full species. E. Icevigaster 
has two new subspecies out of four, while mastersi has a 
couple and cantator has one that is new. E.fuscus proving 
to be the same as E. culicivorus , both of Gould, the former 
name has priority, and six subspecies are admitted. 
The yellow-breasted, black-throated Pseudogerygone palpe- 
brosa is allowed to stand in a separate genus, with three 
Australian and two New Guinean subspecies-—on considera¬ 
tions of colour. 
Very different is that fine bird, Iredaleornis cinereifrons, 
of the Cardwell district, which has a near ally ( armiti ) 
in Papua. 
The Pfjecilodryas series is divided, and Leucophanes is 
kept ; while Plesiodryas is founded as a new genus for 
Megalestes of Salvador!, Papualestes for Myiolestes cyanus 
of that author, Gennceodryas for Eopsaltria placens of 
Ramsay, not to mention Tregellasia and other forms. 
Pcexilodryas superciliosa has two subspecies, P. cervini- 
ventris four, Tregellasia capito three, T. leucops two, but 
the type-species is extralimital. 
It will be remembered that the name Kempiella kempi 
was bestowed in 1913 by the author on a new bird from 
Cape York, of which little is yet known. 
The Thickheads are an interesting series of Australian 
forms, well known for their fine songs and lively coloration. 
Three species are recognised of the yeilow-breasted forms, 
Pachycephala pectoralis, P. robusta, and P. melanura with 
eleven, six, and two subspecies respectively, of which 
P. r. inter cedens is new, as are P. p. bettingtoni, mypong a , 
and interject a. 
The Rufous-breasted Thickhead is still called Lewinornis , 
and L. rufiventris has several subspecies, which will be 
tabulated in the next part. 
Since Watling in his drawings figured P. pectoralis and 
Latham described it, there has been terrible confusion in
