Nidification. The nest of this Blue Chat appears to be very similar to that of the Indian Blue Chat and has been taken on Mt. Victoria and other peaks in the Chin Hills, at about 7,000 feet, by Messrs. McDonald, Wickham and others. The eggs are indistinguishable from those of other species of this genus, and those in the possession of Mr. J. M. J). Mackenzie and myself average about 18-6 x 13"8 mm.
