908 Birds of Celebes: Laridae. 



but Mr. Howard Saunders remarks that with every desire to separate them 

 generically, he is unable to find any structural differences which would warrant 

 such a proceeding. 



S. lunata may be recognised by its grey upper parts and the entirely pure 

 white outer web of the outermost rectrices; S. fuliginosa is larger, has the upper 

 surface blackish, and in summer the black stripe from the eye descends towards 

 the gape instead of running horizontally towards the nostril as in (S. anaestheta. 

 Both /S. lunata and fuliginosa are not unlikely to be found in Celebes. 



GENUS ANGUS Steph. 



The Noddy Terns are easily distinguishable from the other Terns by the shape 

 of their tails and by their coloration. In Anous the tail of 12 feathers is more 

 than half the length of the wing, graduated, the fourth pair of rectrices, 

 counting from the outside, being the longest ; its plumage is of a uniform soot}' 

 black or brown, with the head above gi'ey in the typical forms. They range over 

 the warmer seas, breeding in colonies and laying a single egg at a sitting. 

 The nostril is situated rather far forward, the anterior margin reaching to the 

 middle of the bill.
