Of the five eggs of the Sociable Lapwing in the Collection, two 

 'are distinctly pyriform and three are somewhat sharply pointed 

 ovals. They are in every case gloss-less. The ground-colour is 

 olive-buff, and this is rather sparingly spotted and blotched with 

 dark brown or black and some underlying pale purple. The 

 markings are more prominent at the larger end than elsewhere. 

 The examples measure from 1*65 to 1-9 in length, and from 1*3 to 

 1-30 in breadth.
