to be confined to the hills and mountains of the central part 
of the island.

The White-vented Laughing-Thrush is peculiar to the 
forest-clad ranges of the island. 
The specimens collected by Mr. Goodfellow at elevations 
of from 5000-7000 feet differ from the type of D. pecilo- 
rhynchus, and from other specimens in the British Museum 
collected by Swinhoe, in having the vent and under tail- 
coverts pure white instead of buff, and the upper parts rather 
more olivaceous ‘and less rufous. It is possible that these 
differences may indicate a slightly different highland form, 
but on this point I am not quite satisfied, as the buff of the 
under-tail-coverts in Swinhoe’s birds (in one of them these 
feathers are partly white) may be due to stain, and the 
different tint of the upper parts may be seasonal. To settle
