“Tris chestnut, orbital space sage green, bill horn, 
lower mandible yellowish, feet pale yellowish flesh. 
Exceedingly common oyer the whole of the northern 
third of the Malay Peninsula and in the Langkawi group, 
frequenting low trees in secondary jungle and shrubs and 
bushes at the edges of open spaces. 
The large series in the F.M.S. Museums shows consider- 
able variation in the depth of tint of the buff on the lower 
surface and in the width and intensity of the black shaft stripes 
on the breast as is noted by Gyldenstolpe. The differences are 
apparently due to age and are not correlated with locality.

“Tris red, reddish chestnut or orange, bill slate, 
black on culmen, feet flesh or brownish flesh.”’ 
Diametrically opposite opinions have been expressed by 
Grant and Hartert (loc. cit.) on the separability of the northern 
and southern forms of this species, Turdinus abbottt, Blyth, 
Journ. Asiat. Soc. Bengal. xvi, p. 601 (1845), type from Ramree 
Id., Arakan, and Malacopterum olivaceum, Strickland, Ann. and 
Mag. Nat. Hist. xix, p. 132 (1847), type from Malacca. 
As I have suggested elsewhere (Ibis, 1915, p. 749) much 
of the discrepancy is probably due to the rapidity with which — 
skins of this and other allied Timeliine species fade.
