when immature and when adult, from the other eastern Lint- 
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 Limnaetus. 
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 c 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- 
zaetus devillii,” figured and described by that gentleman in 
the f Bulletins de l’Academie Royal de Belgique/ 2nd series, 
vol. xxxviii. pts. 1 & 2, and found them to he immature ex¬ 
amples of L. isidori —that figured by Dr. Dubois on pi. 1 as 
“ S. devillii, adult/'’ being the first year’s plumage of L. isi¬ 
dori, and that represented on pi. 2 as te 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 f 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.
