evident that} both these alleged species are subject to considerable 

 colour-variations ; and we have been unable, after careful exam- 

 ination and measurements, to detect any such difieronces as 

 should entitle them to be ranked as distinct. We, therefore, 

 consider that Schlegel's //. orientalis is merely a variety of 

 7/. berigora, into which latter, as the type of the genus, the 

 former should be merged. We can, further, detect no difference 

 between eggs in the South Australian collection whicli are 

 ascribed J'espectively to tlie two species. 



A nest of Hieracidea, sp., was found upon the burnt trunk of 

 a tree, about three feet from the ground, in the Victoria Desert 

 (Camp -57).

Oreoica sp. — A second male specimen of Oreoica, considered 

 by Mr. Helms to ditfer from 0. cristata, because the blacks of 

 the Barrow Range district distinguish it by a separate name, is 

 possibly the same bird in its inmiature plumage, but as the 

 specimen previously referred to and a female of the same species 

 from Mildura (Victoria) are all we have for comparison, it would 

 be unsafe at present to declare the bird under consideration to 

 be a distinct species. This specimen has the base of the beak 

 light-brow]i. Both specimens from the Barrow Range appear to 

 have the beak proportionally stronger and wider vertically than 

 the Mildura-specimen. 



The black markings on the head and breast, and also the 

 white face, are very faintly indicated by darker and lighter 

 shades of brown. The crown of the head, which in the male 

 specimen of 0. cristata is deep black, is in this specimen very 

 faintly marked and mixed with grey. The greyish tinge of the 

 neck gradually changes into fawn-colour towards the rump, and 

 the latter tint is more vivid on the upper- and under tail-coverts. 

 Under surface and sides fawji-coloured, the latter being the 

 darker. Feathers of the upper surface, wing and tail l)rownish, 

 juargined with fawn-colour. 



Chlamydodera guttata, (Jould. 



Three beautiful male specimens of this species, which apparently 

 is still rare in Museums, were collected in the Barrow Range. 

 They agree with C. mactdata in respect of size, but the colourings 

 are far more vivid. 



Mr. Helms informed us tliat this bird is not uncommon in the 

 locality mentioned.
