Two sets of eggs of the Hooded Hangnest are of a pointed oval 

 form and almost devoid of gloss. They are of two types : two 

 examples are plain white, while the remainder have the ground- 

 colour pinkish-white or greyish-white, marked with twisted lines 

 and blotches of deep chocolate-brown and lilac-grey, much as in 

 /. haltimore and /. buUocki. They vary from -94 to 1*05 in length, 

 and from '66 to '68 in breadth.
