For an opportunity of examining an authentic nest and egg of 
the New South Wales, Cat-bird, Ailurnidus viridis, Latham, I am 
indebted to Mr. W. J. Grime, a most enthusiastic and persevering 
oologist, who recently procured two nests of this species on the 
Tweed River, and sent the following notes relative to the taking 
of them : — 
“On the 4th of October, 1890, I was out looking for nests 
accompanied by a boy. I left him fora little while to go further 
in the scrub, and on my return he informed me he had found a 
Cat-bird’s nest with two eggs in, one of which he showed me, the 
other one he broke descending the tree. I went with him to the 
nest and found the old birds very savage, Hying at us, and Hutter- 
ing along the ground. The nest was built in a three pronged 
fork of a tree, about fourteen feet from the ground. The tree 
was only four inches in diameter, and was in a jungle or light 
scrub, about fifty yards from the edge of the open country. I 
felled the tree and secured the nest, of which there is no doubt 
as to its being authentic, as the old birds strongly objected to my 
taking it. The eggs had been sat on for a few days and were 
partially incubated.” 
In a subsequent letter dated November the 8th, Mr. Grime 
writes, “ To day I found another Cat-bird’s nest and drove the 
parent bird off it myself. I thought I had more eggs as the Cat¬ 
bird would not leave the nest until fairly shaken out, but when 
1 examined the nest found two young birds in it, apparently just 
hatched a couple of days.” 
The nest of Ailuraxlus viridis, is a beautiful structure, being 
bowl-shaped, and composed exteriorly of long twigs, entwined 
around the large broad leaves of Ptarietia aryyrodendrou, and 
other broad-leaved trees, some of the leaves measuring eleven 
inches in length by four inches in breadth. The leaves appear to 
have been picked when green, so beautifully do they fit the rounded 
form of the nest, one side of which is almost hidden by them. The 
interior of the nest is lined entirely with fine twigs. The nest of 
Ailuruedus viridis is similar to that of A. maculusus, but larger, 
and both of them can readily be distinguished from those of any
