146 Mr. J. H. Gurney's Notes on 



allude ; but I ueed merely do %o, as I have nothing to add to 

 Mr. Sharpens account of the only species comprised in it^ H. 

 cachinnans , which, as it seems to me, is the sole representative 

 of the Circaetine group on the continent of America. I 

 therefore pass on to the genus Circa'etus, all the species of 

 which are African, and all, as far as is known, except C. 

 gallicus, exclusively so. 



The geographical range of C. gallicus^ is considerably ' 

 wider than that of any other species of the genus. A sum- 

 mary of the countries which it inhabits is given in Mr. 

 Sharpe's volume ; and fuller details on this head will be found 

 in Mr. Dresser's article on this species in his work on the 

 Birds of Europe, including some particulars of its range 

 " through Central Asia into Northern China,^' which is not 

 alluded to by Mr. Sharpe, and which has been subsequently 

 also recorded in Prejevalsky's 'Birds of Mongolia^ (vide 

 ' Ornithological Miscellany,' vol. ii. p. 145), and in David and 

 Oustalet's 'Oiseaux de la Chine,^ p. 21. 



Proceeding to the consideration of the remaining species 

 of the genus, I may observe that Mr. Sharpe gives the habitat 

 oiCbeaudouini as "Senegambia and North-Eastern Africa ;" 

 but the latter phrase must not be taken in its fullest sense : 

 one of the specimens in the Norwich Museum, obtained from 

 the late MM. Verreaux, was said by those gentlemen to 

 have been obtained in Nubia (as recorded in ' The Ibis ' for 

 1862, p. 213, footnote) ; but, with this exception, the only 

 North-east African localities for this species with which I 

 am acquainted are those recorded by Von Heuglin, viz. 

 Southern and Eastern Kordofan and Eastern Senuaarf. 



In the case of C. cinerascens, Mr. Sharpe has omitted to 

 give his usual summary of the localities where this species 

 occurs ; and I may therefore mention that it has been met 

 with both in Western and in Eastern Africa. As regards the 

 West, the British and Norwich Museums possess several 



* I consider C. orientalis of Brehm synonymous with C. gallicus, on 

 which point see Mr. Dresser's note in ' The Ibis ' for 1875, p. 102.
