densely speckled and mottled all over with purplish-grey. ‘hey

Another egg, also referred to this species, is pale bluish-green 
sparingly spotted with distinct spots and dots of dark brown and 
purplish-grey. It measures about -77 by -59. The description 
given in Sharpe’s edition of Layard seems to refer to an egg of 
this type.

Four eggs of Vieillot’s Knotch-billed Weaver are of a rather 
short oval shape, pure white and without gloss. They measure 
respectively : -68 by ‘55; °68 by °55; -68 by -52; and -67 by -53. 
Eggs of this species have been described by Nehrkorn and others 
as yellowish-white or salmon-colour, with underlying yellowish- 
brown marks and clear reddish-brown spots, 
There is no reason to doubt the correctness of Mr. Kemp’s identi- 
fication, and probably those described by Nehrkorn have been 
wrongly referred to this species,
