The eggs of the Indian River-Tern are of a very broad oval form, 

 •extremely blunt at the smaller end, alid frequently almost elliptical 

 in shape. The ground varies, being sometimes a greenish grey or 

 pale greenish stone-colour, and at other times a pale buff or dark 

 cream-colour, occasionally tinged with pink or with olivaceous. 

 The markings, which are deep brown of one shade or another, 

 consist of small blotches, spots, short lines and irregular streaks, 

 and are fairly evenly distributed over the shell. In a small propor- 

 tion of the specimens, the blotches are large, coarse, and few in 

 ■number. The underlying markings consist of clouds and spots of 

 pale purple. The eggs measure from 1'5 to 1-75 in length, and 

 from 1-17 to 1-32 in breadth.
