Family PELECANlDiE. 



The eggs of the Pelicans are usually cither of an elliptical or of a 

 biconical shape, both ends being precisely alike ; a few specimens, 

 however, are of an ordinary oval form. The shell is strong, slightly 

 rough, and white, covered more or less with a layer of somewhat soft 

 chalky matter, which is often deposited in uneven patches and 

 wrinkles. 



The eggs of all the Pelicans are very similar.
