Birds of the Philippine Islmids. 465 



marked ^ is not an immature bird, as suggested by Messrs. 

 Bourns and Worcester, but perfectly adult. A mistake in 

 sexing may have been made — such accidents must occasion- 

 ally happen to every collector, however careful he may be. If 

 my conclusions are wrong — and I am quite ready to admit 

 that they may be, especially after reading the above-mentioned 

 letter in ' The Ibis ' — then the sexes of two out of the 

 five Kingfishers sent have been wrongly determined by 

 Mr. Whitehead, such a mistake on his part being hitherto un- 

 known, I have already pointed out the perfectly appreciable 

 difierence in the bill in these two supposed species, but should 

 it be proved that they are merely sexes of the same bird, it 

 follows that this difference is also merely sexual. There were 

 no more examples of these birds in the Lepanto collection, but 

 Mr. Whitehead has promised to send more shortly, and to 

 take particular care to ascertain the sex of each correctly.
