In 1878 one of Hume’s collectors obtained an immature thrush 
from the hills of Rembau, which was identified with the species 
described by Grey from a native drawing from a specimen procured 
in Upper Burma, while Dr. Abbott also collected specimens identified 
as G. interpres by Richmond on the hills of Trang, Western Siamese 
States, in 1896; no other examples have been recorded from the Malay 
Peninsula. Hume relied on the absence of a white wing bar in his 
specimen to separate it from G. interpres, but Oates, loc. cit., states 
that the specimen is in moult and that the sprouting feathers appear 
to possess this feature which is fully developed in our specimen 
from Tampin. Our collectors confused the bird with immature 
Hyrdocichla ruficapilla which affects similar situations and which 
they have been told not to collect in numbers, and this perhaps 
accounts for its not having been obtained before. Possibly also, as 
is the case with the other species of Geocichla in the Peninsula, the 
species 1s migratory. 
There is, we think, little doubt that the nominal species, G. avensis, 
has novexistence in fact.
