ATRICHIA CLAMOSA, Gow. 
Noisy Brush-bird. 
Atrichia clamosa, Gould in Proc. of Zool. Soc., January 9, 1844. 
Few of the novelties received from Australia are more interesting than the species to which I have given 
the generic name of Aftrichia. It is one of the discoveries made by Mr. Gilbert, who met with it among 
the dense scrubs of Western Australia, and who had his attention attracted to it by its peculiar and noisy 
note long before he had an opportunity of observing it; and it was only after many days of patient and 
motionless watching among the scrubs that he succeeded in obtaining specimens, and these unfortunately 
were shot at so short a distance from his gun that they were all much mutilated. Future research will 
doubtless furnish us with some highly interesting information respecting the economy and history of this 
curious form, which is evidently destined to tenant the most dense thickets and tangled beds of dwarf 
trees, and consequently, from its recluse habits, rarely to meet the gaze of civilized man. 
The examples forwarded to me by Mr. Gilbert were killed between Perth and Augusta in Western 
Australia, and were all males. The females will doubtless, when discovered, prove to differ but little from 
their mates, except that the black mark on the breast will not be so large or conspicuous. I am led to offer 
this opinion from the circumstance of one of the specimens sent being a young male, which usually re- 
sembles the female during the first year, and in which this mark is less conspicuous than in the others. 
All the upper surface, wings and tail brown, each feather crossed by several obscure crescent-shaped bars 
of brown; the inner webs of the primaries very dark brown, without markings, and the tail freckled instead 
of barred ; throat and chest reddish white, with a large irregular patch of black on the lower part of the 
throat; flanks brown; abdomen and under tail-coverts rufous; bill horn-colour; irides dark brown. 
The figures are of the natural size.
