424 iMr. J. H. Gumey's Notes on 



in that genus to stand under the generic name of Limnaetus, 

 of which L. cahgatus is the type, and under which I would 

 also include L. kieneri and L. isidori, wdiich Mr. Sharpe has 

 separated under the generic name of Lophotriorchis, hut, as 

 I venture to think, on somewhat insufficient grounds. 



I propose to refer first to the genus Limnaetus, and subse- 

 quently to Spiza'etus. 



In the * Proceedings ' of the Zoological Society for 1860, 

 p. 342, my late friend, Mr. G. R, Gray, described and figured, 

 under the name of Aquila gurnerji, a very fine Eagle, which 

 was first obtained by Mr. Wallace in Batchian, but which also 

 occurs in several other islands of the eastern ocean, as enu- 

 merated in Mr. Sharpens volume. Mr. Sharpe includes this 

 species in the genus Spizaetus ; I am, myself, disposed to 

 agree in this view so far as to consider it a somewhat ab- 

 normal species of that portion of Mr. Sharpe's genus Spi- 

 zaetus, for which I would use the more restricted title of Lim- 

 naetus. I think, however, that there is a considerable degree 

 of truth in the remark made by Mr. Gray in his original 

 description of this species, that "^this fine bird partakes of 

 the form of Aquila malayensis ;" and it is for this reason that 

 I allude to it as next in order to that species, which it recalls 

 by its very large (though more curved) inner claw, by its 

 somewhat elongated bill and wings, and by its largely de- 

 veloped and narrowly barred tail ; the iris, however, is of a 

 different character, being stated by Mr. Wallace to be " yel- 

 low-olive^''^. 



Limnaetus gurneyi appears to be always destitute of a 

 crest, in which respect it resembles another and much more 

 typical species, Limnaetus lanceolatus, of Celebes, respecting 

 which I have nothing to add to the notice contained in Mr. 

 Sharpe's volume, except to mention that it also inhabits the 

 Sula Islands f ; and I will therefore proceed now to consider its 

 nearly allied but more widely distributed congener, Limnaetus
