when immature and when adult, from the other eastern Lim- 

 naeti ; and it also has a somewhat less development of the tail ; 

 I doubt^ however^ as I have already mentioned, its being really 

 generically separable from the genus Limna'etus. 



The immature plumage of this Hawk-Eagle will be found 

 described in the addenda to Mr. Sharpens volume at p. 458, 



To the localities quoted by Mr. Sharpe for this species, 

 Batchian, Java, and Ceylon must be added, a specimen from 

 each of these islands being preserved in the Norwich Museum. 

 In ' Stray Feathers,' vol. v. p. 10, Mr. Hume records this 

 species from N.E. Cachar, and adds that " in N.E. India, as 

 In Sikkim, for instance, it is far from uncommon; " it is, 

 however, a decidedly rare species in European Museums. 



Mr. Sharpe associates with L. kieneri, in his genus Lopho- 

 triorchis, L. isidori of N.W. South America, a much larger 

 species, of similar colouring, both in its first and last stages 

 of plumage, but with a more largely developed tail. 



Through the kindness of Dr. A. Dubois, I had the op- 

 portunity, last year, of examining, at the Royal Museum of 

 Natural History at Brussels, the two type specimens of " Spi- 

 zuetus devillii," figured and described by that gentleman in 

 the ' Bulletins de PAcademie Royal de Belgique," 2nd series, 

 vol. xxxviii. pts. 1 & 2, and found them to be immature ex- 

 amples of L. isidori — that figured by Dr. Dubois on pi. 1 as 

 " S. devillii, adult,'''' being the first yearns plumage of L. isi- 

 dori, and that represented on pi. 2 as " S. devillii, jeune," 

 being a very curious stage, intermediate between the first 

 dress of L. isidori and the fully adult plumage figured by 

 Des Murs in the ' Iconographie Ornithologique,^ pi. 1. 



Neither of these immature stages are described by Mr. 

 Sharpe ; but they may be readily recognized by a reference 

 to the figures and descriptions supplied by Dr. Dubois. 



The Norwich Museum contains a specimen of L. isidori 

 in its first, and also one in its last stage of plumage ; but I 

 have never seen the intermediate dress, except at Brussels. 

 It is worthy of note that this intermediate dress has no cor- 

 responding phase, so far as I am aware, in L. kieneri. 



The two specimens of this rare species preserved in the
