IM Рккох'з GROUND-THRUSH was discovered on the Island of Timor very early in the century by Francois 
Қ" Péron, а French naturalist and traveller. Péron was born in 1775, sailed from Havre in the 
* Géographe' under Captain Baudin in 1800, was in Timor in 1801, visited Australia in 1802, 
ій revisited Timor in 1808, returned to France in 1804, and died іп 1810. Péron's Ground-Thrush made 
ind its first appearance in literature іп 1818 under the name of “Le Merle Péron,” Turdus peronii, in the 
di * Nouveau Dictionnaire d'Histoire Naturele' (xx. p. 276). In those days the importance of 
geographical distribution was very little appreciated, the exact places where the specimens brought 
home by the Baudin Expedition had been obtained were confused together, and Péron's Ground- 
Thrush appeared in the Paris Museum with the erroneous locality of * New Holland" attached to it. 
About the year 1828 the species was rediscovered by Solomon Müller on the island of Timor, 
and named by him Geocichla rubiginosa. 
Nothing apparently has been recorded of its habits, which are doubtless the same as those of its 
allies. 
The adult male and female may be described as follows :— 
General colour of the upper parts buffish chestnut, slightly darker on the crown; lores white; 
eye-stripe obsolete; lesser wing-coverts dull buffish chestnut; median and greater wing-coverts 
nearly black, with brown margins, and with large white terminal fan-shaped spots; primary-coverts 
dark brown, with a white streak on the outer web; tertials russet-brown, with pale tips; secondaries 
brown, margined with buffish brown towards the tips and with white at the base of the outer webs; 
primaries, where not emarginated, edged with white; tail-feathers brown, suffused with chestnut 
on the outer webs, the outer pair with a deep terminal wedge of white, nearly an inch in extent, the 
next pair more or less tipped with white; ear-coverts white, crossed by two black bands; underparts 
orange-chestnut, except the chin, throat, centre of belly, thighs, and under tail-coverts, which are 
white, and the cheeks, which are white mottled with black; axillaries dark brown, with white bases : 
lower primary-coverts brown ; lower secondary-coverts white, with dark brown bases. 
Geocichline markings on inner webs of quills, white. 
Bill dark brown, paler at the base of the under mandible; second primary intermediate between 
the sixth and seventh ; tarsi, feet, and claws pale; outer tail-feathers very slightly shorter than the 
longest.
