The eggs of the Eyebrowed Tern are similar to many of those 

 of S. minuta, the ground-colour being of a warm buff and the 

 markings rather small and delicate. In fact, tlie markings are 

 intermediate in size between those on the eggs of S. minuta and 

 those of S. saundersi. Eight specimens vary from 1"17 to 1-23 in 

 length, and from '91 to "95 in breadth.

The eggs of the Black-uaped Tern are of an oval form, but 

 somewhat sharply pointed at the smaller end. The ground-colour 

 varies, being white, creamy white, pale buff or pinkish buff, and this 

 is usually boldly marked with spots and blotches which vary in 

 colour from yellowish brown to chocolate-brown, and are generally 

 more frecjuont at the larger end than elsewhere. The underlying 

 markings of pale purple are of large size and woll-detined. Some- 

 times an example may be found which is marked with only a few 

 dots. The eggs measure from 1-4 to 1-G5 in length, and from 1-05 

 to 1-2 in breadth.
