108 MERULA JAVANICA, 
Both our adult birds have the upper surface, as well as 
the entire head, neck, throat, chest, upper breast, under 
wing-coverts and thighs dark olive-brown, somewhat paler 
brown on fore-neck and chest, and darker brown on head, 
quills and tail-feathers; lower breast, abdomen and flanks 
pale chestnut, centre of abdomen and vent white, under 
tail-coverts olive-brown, all the feathers more or less 
broadly streaked with white along the centres, sides of 
rump with hidden white subterminal markings on some 
of the feathers. Bill, feet and claws yellow. 
The immature specimen differs from the adult in having 
whitish shaft-streaks on some feathers of the upper sur- 
face and still more on throat and chest, and in the lower 
breast, abdomen and flanks being uniform with throat 
and chest instead of pale chestnut brown. These parts are, 
however, intermixed with some chestnut feathers, showing 
the color of the adult stage. The vent and under tail- 
coverts do not differ in color from these parts in the 
adult birds, 
Blyth, in J. A. S. Beng. XVI, p. 143, and after him 
Salvadori, Uce. di Borneo, p. 257, and Seebohm in his 
above cited Catalogue of Turdidae, mention Zurdus con- 
color Temm., but Temminck has never published nor is 
to be found in our Museum any ride SS like 
this in connection with Turdus javanicus. 
As the habitats of this species are mentioned the Islands 
of Java, Sumatra and Borneo. I doubt, however, whether 
any specimen ever has been found in Sumatra, which 
island is mentioned by Bonaparte in his Conspectus Avium 
and after him by Gray and later authorities, without 
mentioning a specimen seen by themselves. The same [ might 
say of Borneo, if there was not enumerated a specimen 
from that island by Seebohm in his above mentioned Ca- 
talogue, but having no special trustworthy statement of 
its origin, it is not out of doubt whether it is really 
obtained in Borneo.
