262 Mr. J. H. Guniey on some Hawks of the 



tlie underparts. In U. approximans the commonest oast of 

 colouring on tliese parts is that represented in the figures of 

 this species in Grould^s ' Birds of Australia^"^ ; but specimens 

 with a more rufous colouring of these bars are not infrequent. 

 A male of this description from the Swan River, which closely 

 agrees with Mr. Gould's plate of his " Astur cruentus," is 

 preserved in the Norwich Museum ; but another male and. a 

 female from the same locality, which are also preserved there, 

 are of the ordinary type of colouring most frequent in adults 

 of U. approx'imans. These three specimens agree in size with 

 the usual dimensions of U. approximans. 



I may add that Mr. E. P. Ramsay's remarks on West- 

 Australian examples of U. approximans, in the ' Proceedings 

 of the Linnean Society of New South Wales,^ vol. iii. p. 174, 

 may be consulted with advantage, and are the result of a 

 wider series of observations than I have had the opportunity 

 of making. 



The specimen in the Cambridge Museum from which Mr. 

 Sharpe drew up the description of " Astur cruentus " in his 

 Catalogue of Accipitres, p. 127, seems to me to be an adult 

 female of U. approximans ; and I believe that Mr. Sharpe is 

 also now disposed to refer it to that species f; but it has 

 the rufous bars on the underparts paler than is the case 

 in any other example that I remember to have examined. 

 The locality where it was obtained is, if I mistake not, un- 

 known, 



New-Caledonian specimens of U. approximans do not 

 appear to me to differ from Australian, the colouring of the 

 adult bird resembling, so far as I have observed, the ordinary 

 type represented in Mr, Gould's plate already referred to. 



The following measui'cments are taken from specimens of 



* Since the above reference to Mr. Gould's great Australian work was 

 penned, that veteran ornithologist has been removed from amongst us ; 

 and I cannot omit this opportunity of paying a tribute of respect to the 

 memory of so eminent a naturalist, and one whose friendship I was privi- 

 leged to enioy for more than forty years.
