The Burmese spotted Babbler was very common on suitable localities over the 
whole of Siam, though more abundant in the Northern parts of the country. It always 
keeps to the thick undergrowth and was seldom seen in the lower trees where it probably 
only retires when on look out for some danger. It has a nice song which it frequently 
utters, and on account of its retiring habits it is more often heard than seen. 
The specimen shot up among the mountains west of Koh Lak differs somewhat 
from the other specimens in my Siamese collection. It has the under surface, with 
the exception of the centre of the abdomen, rich fulvous buff, exceedingly darker than 
in typical birds. The blackish brown stripes on the chest and upper breast are paler 
and narrower; the bill is plumbeous grey instead of horn colour, but in every other way 
it agrees with typical specimens of P. subochraceum.

The birds obtained by me up among the mountains on the Tenasserim boundary west 
from Koh Lak have to be referred to the typical 7. a. abbotti and not to the southern 
race which has been named by SrRickLanD 7’. a. olivacewm. This race inhabits the Malay 
Peninsula at least as far north as to Bandon — where it was found by Roprnson — and 
the island of Borneo. Curiously enough Mr. C. Boprn Ktoss obtained 7. a. olivacewm 
during his recent trip to the Chantaboon district in south-eastern Siam. He obtained 
this bird on a more northern latitude than that one of Koh Lak, why the southern race 
seems to extend further to the north on the eastern side of the Gulf of Siam than on 
the western. 
I only prepared the skin of a single male specimen but shot several others, though 
they unfortunately got spoiled and were not worthy of being preserved. They, however, 
all belonged to the typical race, having the underparts of the body very dark and the 
under tailcoverts deep rufous ochre. 
When observed they were always single, though several specimens could occur 
on rather a small area of land. They generally kept on the ground among the thickest. 
undergrowth; only when being disturbed in some way they flew up in a low tree, though 
very soon diving down to the ground again, where they were jumping about in search 
of food among the dry leaves. 
In the Northern parts of the country I never observed them. One specimen has 
been recorded from Bangkok by Mr. WILLIAmson (Journal Natural History Society of 
Siam Vol. I N:o 2 p. 77). 
My specimen agrees well with the description in the literature but the grey eye- 
brow is very distinct almost reaching to the upper parts of the ear-coverts.
