(2.) S. spilogaster , nobis (J. A. S. B. xxi. p. 353), Hamatornis 
elgini, Tytler (J. A. S. B. xxxii. p. 87), from tbe Andaman Islands, 
where it occurs together with the preceding; also H. bacha of 
Colonel Sykes's list of the birds of the Dukhun (P. Z. S. 1832, 
p. 79), as identified from a specimen in the India Museum pre¬ 
sented by Colonel Sykes, being doubtless that referred to ( loc. 
cit.). This well-marked race inhabits the Indian peninsula and 
Ceylon, and also the Andamans, from which last-named locality 
a fine pair are now living in the Zoological Gardens. It is a 
smaller bird and not so handsome as S. cheela, with less deve¬ 
loped crest and much less of black upon the crown, the tail- 
markings quite different, having the black subterminal band con¬ 
spicuously much less broad. Some individuals may very probably 
show considerable similarity to the Malayan S. bacha , which 
would account for Professor Schlegel identifying a Cinghalese 
specimen with the Malayan bird; still the tail-bands should be 
differently placed * *. 
(3.) S. bacha (Daudin), Falco bido, Horsfield, which I suspect 
to be peculiar to the Malayan subregion. It is again smaller, with 
a darker shade of colouring, and fewer spots. 
(4.) S. rufipedus , Gould (P. Z. S. 1857, p. 222), Circaetus 
bacha celebensis , Schlegel, from Celebes. 
(5.) S. holospilus (Vigors), Gray and Mitchell (Gen. Birds, 
pi. 7), from the Philippines and South China. 
S. spilogaster has accordingly to be added to the fauna of 
the Indian subregion. 
41. P OLIOAETUS ICHTHYAETUS. 
Young (in abraded plumage) figured as Haliaetus lineatus by 
Dr. Gray, in his ( Illustrations of Indian Zoology/ from Gene¬ 
ral Hardwicke's drawing. This figure has been erroneously 
assigned to Milvus govinda; but the present genus has the same 
in Formosa, appears to be identical with S. cheela , and that specimens 
from that island and from Northern India are rather larger than those from 
Southern India, Siam, and the Malay peninsula.— Ed.] 
* [We learn from Mr. Gurney that he has never seen an Indian ex¬ 
ample of this bird, but that specimens from Ceylon and the Andamans 
appear to be absolutely identical with S. bacha ( Falco bido, Horsf.) from 
Java, Sumatra, Borneo, and Singapore.— Ed.]
