THE SHELL IBIS.

The Shell Ibis occurs sparingly throughout the province; in most places it is only a cold weather visitant, but in Sind it breeds during August. The nests are platforms composed of twigs. The eggs, four or five in number, are of an oval shape, of a creamy-white color when fresh, but soon get stained as incubation proceeds.
They measure 2.24 by 1.6.
