One was shot at Kuala Kedah in November 1907. The 
Malay name for the bird is Lang siput, or Oyster-Hawk 
derived from the idea that at the turn of the tide it flies up 
river uttering its call to warn the shellfish of the return 
of the water. 
61. POLIOAETUS TCHTHYAETUS. 
Polioaetus ichthyaetus (Horsf.) ; Sharpe, tom. cit. p. 452. 
Not rare in the northern portion of the Peninsula on 
the coast and inland wherever there are rice-fields, but not so 
numerous further south. 
In the interior on the rivers flowing through dense jungle 
its place is taken by the smaller species P. humilis. On some 
rivers, notably the higher reaches of the Tembeling and its 
tributary the Tahan, in Pahang, almost every reach is in¬ 
habited by a pair of these birds, which lumber along in front 
of the canoe as the traveller advances up stream.

We collected three specimens of the large Fishing-Owl 
on the edges of the rice-fields at Chong in the interior of 
Trang. 
It does not appear to have been recorded from further 
south than Central Tenasserim, so that the present locality 
shews a considerable extension in range for the species.

Ketupa javanensis Less. ; Sharpe, tom. cit. p. 8. 
Very common everywhere in suitable localities throughout 
the Peninsula.

Syrnium sinense (Lath.); Sharpe, tom. cit. p. 281. 
This Wool-Owl is generally found in orchards and villages 
roosting in the large fruit-trees and quartering the rice-
