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. ftdiginosa 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 iS. 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 grey 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.
