 " Iris chestnut, orbital space sage green, bill horn, 

 lower mandible yellowish, feet pale yellowish flesh. 



Exceedingly common over 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 G\ ldenstolpe. The differences are 

 apparently due to age and are not correlated with locality.

Diametrically opposite opinions have been expressed by 

 Grant and Hartert Hoc. cit.) on the separability of the northern 

 and southern forms of this species, Turdinus abbotti, Blyth.

 Id., Arakan. and Malacoptcrum olivaceum, Strickland, Ann. and 

 Mag. Nat. Hist, xix, p. 132 (1847), type from Malacca. 



As I have suggested elsewhere (Ibis. 1915. p. 749 1 much 

 of the discrepancy- is probably clue to the rapiditv with which 

 skins of this and other allied Timeliine species fade.
