The Buzzard-eagles are of small-medium size (about as big as a Crow); wing 
long, primaries overreaching the secondaries by about one-third of the wing- 
length; tail moderate, slightly rounded; tarsus naked (except for the upper 
fourth in front), covered with polygonal scales, the. largest in front; 
toes rather short; cere large, occupying two-fifths of the exposed culmen, bill 
not powerful for a bird of prey. Preys on reptiles, amphibians, insects. Four 
species, among them migratory and probably stationary forms, found from India 
and S. E. Siberia to New Guinea; also N. E. Africa.

but we do not know upon what grounds this statement was made. As this learned ornithologist omits Celebes 
from the range of P. ichthyaetus in his tables showing the distribution of Bornean birds in The Ibis 1890, 
274, we conclude that he has since found reason to believe himself to have been in error, especially as no 
such bird has been recorded from Celebes of late years. When Hume (Str. F. Y, 129), Legge (B. Ceylon, 74),
