‘and the exact locality, scrub adjacent to the Olinda Creek, where I 
‘found the happy family, fully fledged, swelling out their nest, with 
their handsome yellow-breasted parent in attendance. There wag 
an extra solicitous tone in his sweet voice, especially when T 
‘commenced to handle and examine the youngsters. On such clear 
evidence then I am content to expunge Pachycephala rufogularis 
from my list, seeing it is the youthful P. gutturalis. 
However in justice to Dr Ramsay, I find he states in “ Notes 
and References " to his “ Tabular List,” that, “ P. gilberti is a good. 
species, but P. rufogularis is very doubtful. Specimens in the 
British Museum do not appear to belong to either species, although 
supposed to be P. rufogularis (Gould).”

inside with fine grass. Dimensions, over all about 8% inches b 
2i inches in depth. Egg cavity 2i inches across by 14 inches

both ends nearly alike; texture of shell, fine, with a trace of gloss 
upon the surface; color, light yellowish-white of a darker shade 
about the upper quarter where are spots of umber and dull groy, 
the latter appearing as if beneath the surface of the shell. Some 
examples have the ground color more yellowish as in those of tho 
White-throated Thickhead (P. gutturalis,) with a greater number 
of markings distributed over the surface. Dimensions in inches of 
cluteh—(1) '98 x :63; (2) :97 x '63. Odd examples—(Long)

OssERVATIONS.—In Western Australia in the acacia scrubs 
protected by the beautiful leafed Eucalypt (E. calophylla,) I fre- 
quently observed this lovely bird whose golden breast vied in color 
with the acacia’s bloom. The male bird stands a perfect lover as 
he calls *sweet" to his grey-colored mate in another tree. She 
answers lovingly in identical note, ** sweet.” 
Gould regarded the Western and Eastern White-throated 
Thickheads as possibly identical, while Dr Ramsay in his “Remarks” 
on his * Tabular List," states:— 
“Winding it necessary to separate the Yellow-breasted 
Pachycephala of Western Australia from that of N.S. Wales, I
