Geocichla erythronota, G. dohertyi, and G. leucoloema as its nearest allies. Of these three species the
chestnut backs of the two former, and the black lores and ear-coverts and the white throat of the
latter, serve to distinguish, them at once.
The adult male and female may he described as follows :—General colour of the upper parts
dark slaty grey, sharply defined from the nape, which, like the crown and forehead, .is brownish
chestnut, brighter towards the nape ; lores white ; eye-stripe obsolete ; lesser wing-coyerts nearly
black, the lower ones tipped with white'; median coYerts white ; greater coYerts nearly black, with large
white terminal fan-shaped spots ; primary-coverts black ; tertials brown; secondaries and primaries
brown, with slaty-grey edges to the unemarginated portion of the outer webs ; tail-feathers brown,
the outer pair broadly and the next pair narrowly tipped with white.
Ear-coverts black, crossed by a broad white hand. Chin, throat, and upper breast black ; rest
of underparts white, suffused with'buff on the flanks, and marked on the- lower - breast with large
black fan-shaped terminal spots, which become obscure on the flanks ; axillaries dark slaty grey, with
white bases ; lower primary-coverts nearly black ; lower secondary-coverts white, with nearly black
bases.G
eocichline markings on inner webs of quills, wbite.
Second primary intermediate in length between the seventh and eighth ; “ hill very dark brown ;
legs pinky white; claws horn-brown; iris chocolate,” (A. E. Everett). Outer tail-feathers very
slightly shorter than the longest.
Length of wing 4-25 to 4'0 inches, tail 2-4 to 2-2 inches, culmen 0'77To 0'7 inch, tarsus 1T6 to
IT inch ; bastard-primary projecting beyond the primary-coverts, its exposed portion measuring 1-0
to 0 ’85 inch. v - ,
Young in fir s t plumage. All the small feathers of the upper parts dull chestnut with pale shaft-
streaks, but the wing-coverts and quills scarcely differing from those of adults. Gn the underparts
the biack feathers of the adults are replaced by dull pale chestnut feathers with obscure black tips.
The Plate represents an example in the British Museum brought from Lombok by Dr. A. B.
Wallace. The figure in the distance is a copy of the so-called Ava Thrush, figured in Griffith’?
edition of Cuvier’s ‘ Animal Kingdom.’
The type in the Leyden Museum was figured in 1828 in Temminck’s ‘ Planches Coloriées,’ but
the figure is not a very good one, the pale lores and the white band across the ear-coverts
being omitted.
