Geocichline markings on inner webs of quills, white.
Bill sooty grey above, yellow below; second primary intermediate in length between the sixth

Length of wing 4*45 to 4*3 inches, tail 3'2 to 3*1 inches, culmen 1*0 inch, tarsus 1*3 to 1*2 inch;

The immature example shows remains of the first plumage, some feathers on the nape and some
of the scapulars having pale shaft-streaks and black tips, while most of the feathers of the- upper
parts show more or less obscure dark margins. The crescentic spots on the flanks extend also to the
breast.
The Plate is drawn life-size from the type in the British Museum. It has previously been
figured, but only two-thirds of the natural size (Forbes, ‘ Proceedings of the Zoological Society o f
London,’ 1883, plate lii.). An uncoloured copy of this plate is given by Forbes in his ‘Naturalist’s
Wanderings in the Eastern Archipelago ’ (p. 337).
