“The eggs of the Satin Bower-bird are slightly larger than those 
of the Spotted Bower-bird, more strongly marked if anything, 
have the same thin delicate shell and elongated form ; in length 
they average 1*6 inch, in breadth l’l inch, are of a light rich 
cream-colour, and are marbled all over, more closer at the thicker 
end, with short wavy irregular lines of deep olive-brown, umber, 
and sienna. These markings are peculiar in form, some resembling 
ill-shaped figures of fives, eights, and sevens, others being long and 
wavy, but few if any encircling the shell altogether. These lines 
are thick in proportion to their length, and in places are looped, 
curled, and twisted in various directions, often crossing each other 
at right angles.” (Ramsay, P.Z.S., 1S75, p. 112.) 
In the Proceedings of the Zoological Society of London for 
1875 (March 2nd) p. 112, where I first • described the egg of this 
species, I laid stress on the peculiar short, wavy, and irregular 
markings, drawing attention to the somewhat similar characters 
exhibited on the egg of Chalamydodcra macidata ; at that time I 
had only two perfect specimens from nests taken in the Wollongong 
district. Since then however, I have received two well 
authenticated sets, which show that the eggs previously described 
were not of the normal form, hence the necessity for describing 
the most common variety, in which irregular blotches and spots 
form the characteristic markings. The eggs vary in proportionate 
length, but are usually long ovals, seldom oven slightly swollen 
towards the thicker end; the ground colour is of a rich cream or 
light stone-colour, spotted and blotched with irregular patchy 
markings, and a few dots of umber and sienna-brown of different 
tints, in some almost approaching blackisli-brown, in others of a
