NORFOLK ISLAND THICK-HEAD. 
with greenish-olive; chin, throat and sides of the neck yellowish-white, indistinctly 
flecked with brown ; chest bright brownish-buff ; belly and abdomen huffy-white ; under 
tail-coverts pale primrose-yellow; under wing-coverts and axillaries greyish-white; 
under-surface of quills dark ash, with the inner web whitish-huff. Collected on Norfolk 
Island on the 6th of June, 1903. 
Nest and eggs. The cup-shaped nest is not very deep and composed of small twu'gs, rootlets, stalks 
of grass and other small plants, skeleton leaves, sometimes sheeps’ wool, pieces of thread, 
paper, etc., lined with uniform fine stalks and grasses. They contain 2 or 3, and in two 
cases 4 eggs. The latter vary from white (seldom) to brownish-buff and are somewhat glossy. 
They are marked, often in a belt round the thicker end, in the way of Shrikes’ eggs, with 
deep rufous-brown spots and deeper lying paler grey or bluish-grey patches. They measure: 
26 X 18 5, 25-5 X 18 3 ; 24 X 18,24 X 18 2,23'5'x 18, 26'8 X 17 6 ; 25 X 185.23-3 X 18; 
25- 6 X 18-6, 25 X 18'6, 251 X 18 5 ; 25‘5 X 18‘7, 25 X 19 ; 25'6 X 18‘6, 26 X 18’5, 
26 5 X 18-5; 24 5 X 18 7, 26 X 18 4; 25 3 X 19, 25 5 X 18 7, 25 3 X 18'6 ; 26 3 X 17 8, 
26- 8 X 18; 25-3 X 18'8, 23'8 X 182, 24 X 186, 253 X 19 ; 26 X 18, 262 X 18 mm. 
The eggs of this Pachycepliala agree therefore in character closely with those of other larger 
Pachycephala, and strikingly show the Laniine type, while those of P. rufiventris (Lewinornis 
Math.) and subspecies are smaller and much darker.
