moss-covered rock, the entrance to tlie bower facing down hill. The pyramidal walls forming 

 it were constructed around two small trees, and measured three feet six inches high on one 

 side and three feet on the other ; seven inches apart across the floor of the bower, and two feet 

 two inches apart at the top. The inside of the higher wall was well covered for two feet with 

 pieces of moss and white flowers, which got less in number as they approached towards the 

 top ; a few flowers w'ere also placed on the ground in front of the bower. Mr. Day also 

 sent me a photograph of a bower, found by him on Mount Bartle Frere on the qth October, 

 1896, measuring six feet two inches in height on the higher side. It is of the usual double 

 pyramidal form with a thick stick or root connecting the two sides about eight inches from 

 the bottom, the inside of the higher wall being partially covered w'ith apparently white flowers. 

 Unfortunately the bower was surrounded with dense vegetation, and the photograph obtained 

 is too indistinct for reproduction. 



Mr. R. Grant informs me that all the specimens brought back by Mr. E. J. Cairn and 

 himself from their North-eastern Queensland expedition in i88g, were obtained on Mount 

 Bartle Frere and diflferent peaks of the Bellenden Ker Range. Also, that when at the bower 

 the male erects his crest and expands the tail-feathers, the central pair of the latter, being 

 shorter gives it when spread a rounded fish-t.ail appearance. The call is a frog-like croak, 

 very difiicull to imitate, and the stomachs of the birds they procured contained small fruits, 

 berries, and insects. 



Young males are sitnilar in plumage to the adult female, the lirst sign of their apjiroach 

 to maturity appearing in the strong golden-olive wash to the back, and the gradual change to 

 bright golden-yellow of the feathers on the breast; the under-surface of the quills and tail- 

 feathers, too, are washed with golden-yellow, and all their shafts are bright golden-yellow. 

 Like the Regent Bower-bird it is probable that the fully adult plumage of the male of this 

 species is assumed by a change of feather colour, more than liv moult. The bird figured 

 represents an adult male.
