PACHYCEPHALA XANTHROPROCTA, Gould. 
Gould, Proc. Zool. Soc., 1837, p. 149. 
The nest of the Norfolk Island Thickhead closely resembles 
that of the well known P. gutturalis of Australia. Dr. Metcalfe 
informs me it is an open cup-shaped structure composed entirely of 
twigs, and lined inside with dried grasses, and is usually placed 
in lemon, and other low trees, and that the eggs are three or 
four in number for a sitting. Of two eggs forwarded by Dr. 
Metcalfe, one is an elongated oval, of a rich creamy-white ground 
colour, with spots, freckles and dots of dark umber-brown, and 
nearly obselete markings, of sepia on the thicker end, becoming 
confluent and forming a broken zone. Length 1-05 x 072 
inch. The other specimen is oval and nearly equal in size at both 
ends, the ground colour being of a darker shade than in the 
previous specimen, with rich umber-brown spots, freckles and dots, 
and spots of bluish-grey on the larger end appearing as if beneath 
the surface of the shell, forming an irregular shaped cap or patch. 
Length 1 xO-75 inch. These eggs could not be distinguished 
from some of the varieties of P. gutturalis. September 
and the two following months constitute the breeding season of 
this species. 
RHIPIDURA PELZELNI, G. R. Gray. 
Pelzeln’s Fantail. 
G. R. Gray, Ibis, 1862, p. 226. 
The nidification of Pelzeln’s Flycatcher is similar to that of 
other members of the genus Rliijndura, found in Australia and 
elsewhere. Dr. Metcalfe informs me the nest is a small, round, 
deeply cup-shaped structure, outwardly composed of mosses, 
fibrous roots and cobwebs, lined inside with finer grasses and a 
few feathers, and is usually placed on the branch of a low tree. 
Eggs three or four in number for a sitting, oval in form, white, 
with dull coloured light brown markings, and several blotches 
and spots of pale bluish-grey on the thicker end, appearing as if
