The eggs of the Sacred Ibis taken in Egypt and now in the 

 Collection are of a very narrow and lengthened oval form. They 

 are much stained with yellow and brown smears, but were probably 

 white originally. They measure respectively : 2"o7 by 1"63 ; 2'57 

 by 1"56. The other examples are white, marked, chiefly at the 

 larger end, with small spots of yellowish brown. One is a narrow 

 oval, measuring 2-55 by 1-63 ; the other is a broad oval, 2-53 by 

 1-8.
