454 Mr. J. H. Gurney on some 



latter character is probably a variable oue, as in the present 

 specimen of U. etorques the underparts are veiy distinctly 

 cross-barred, and more so than in U. dampieri. The dark 

 cross bars on the breast in this specimen are rufous much 

 tinged with greyish brown ; on the abdomen they are a pure 

 rufous^ with the interspaces white; in U. dampieri these 

 interspaces are pale rufous, and narrower than in this example 

 of U. etorques. I may also mention that in the latter the 

 tail shows nine perceptible, though not very distinct, dark 

 cross bars on the central rectrices, the lowest being sub- 

 terminal. 



From these particulars, and those recorded at p. 127, it 

 will be seen that the differences between the two species 

 comprise, in addition to those of measurement, the colora- 

 tion of the irides and of the chin and upper throat, also the 

 character of the transverse markings on the under surface 

 and on the central rectrices. 



3. An example of Nisaetus morphnoides (Gould), appa- 

 rently adult, and resembling in coloration the Queensland 

 specimen described by Mr. Sharpe in the P. Z. S. for 1875, 

 p. 338, except that the upper tail-coverts are dark brown, 

 partially cross-barred (but not tipped) with white, and that 

 the shaft-marks on the underparts are dark brown^ rather 

 than black, also that there is no tinge of chestnut on the 

 under wing- coverts. 



I am not aware that this species has hitherto been recorded 

 from New Guinea, where this specimen was obtained, also 

 on the Astrolabe Mountains, by Mr. Goldie. 



It would seem, by its small size, to be a male, and to be 

 shorter in the wing (which appears to be fully grown) than 

 two Australian males of which the measurements are given 

 by Mr. E. P. Ramsay in his 'Catalogue of Australian Acci- 

 pitres/ p. 29.
