NEW SPECIES OF AUSTRALIAN BIRDS. 
Mr. Gould (Aug. 25, 1840) called the attention of the 
Members of the Zoological Society to an extraordinary piece 
of Bird-architecture, which he had ascertained to be constructed 
by the Satin Bird, Ptilonorhynchus holosenceus , and another of 
similar structure, but still larger, by the Chlamydera metadata. 
These constructions, Mr. Gould states, are perfectly anomalous 
in the architecture of birds, and consist in a collection of 
pieces of stick and grass, formed into a bower; or one of 
them (that of the Chlamydera') might be called an avenue, 
being about three feet in length, and seven or eight inches 
broad inside; a transverse section giving the figure of a 
horse-shoe, the round part downwards. They are used by the 
birds as a playing-house, or u run,” as it is termed, and are 
used by the males to attract the females. The u run” of the 
Satin Bird is much smaller, being less than one foot in length, 
and moreover differs from that just described in being decorated 
with the highly-coloured feathers of the Parrot tribe; the 
Chlamydera , on the other hand, collects around its “ run” a 
quantity of stones, shells, bleached bones, etc.; they are also 
strewed down the centre within. Mr. Gould spent much 
time in observing the habits of those birds, and was fully 
satisfied'that the " runs” were actually formed by them, and 
constructed for the purposes described. 
At a Meeting of the Zoological Society held on the 10th 
November, 1840, Mr. Gould exhibited the following specimens, 
in addition to those already mentioned ( Tasm. Journ. 305, 
306)
