Irides: white, yellow or yellowish white. Bill: horn colour. Legs: dirty yellow. 
Very common in suitable localities over the whole country south to about Lat. N. 
11° 45’. 
The Yellow-breasted Babbler inhabiting Siam, and of which I have a large series, 
is decidedly smaller than the measures being recorded for M. g. rubricapillus Tick. 
HARRINGTON gives the wing in that species as measuring from 57—61 mm. and the 
tarsus to 20 mm. As seen by the measurements given above none of my specimens 
have a wing measuring more than 55 mm. and the tarsus not more than 18 mm. 
Unfortunately I have no specimens from Burma, Assam or Sikkim to compare 
with, but two specimens from Ahsown in Tenasserim are absolutely identical with Sia- 
mese birds. 
Therefore I believe that the race of the Yellow-breasted Babbler which inhabits 
Siam and Tenasserim ought to be separated under a new subspecific name which I pro- 
pose to be Mixornis gularis minor. 
Description: Similar to M. g. rubricapillus, Tick., but differing from that bird in 
being smaller. The extreme point of the forehead and the lores are pale yellow without 
any black shaft-stripes; supercilium very pale yellow; crown ferruginous, blending on 
the nape with the olive green of the upper plumage; ear-coverts yellowish green with 
pale shafts; chin and throat »strontian yellow» (Ridgway, Plate 16); the feathers of the 
throat having black shaft-stripes; remainder of under surface dull greenish yellow. 
Type: § ad. Pak Koh, Northern Siam */, 1914. Coll. N. GyLDENSTOLPE. 
Specimens examined: 15 from Siam and 2 from Tenasserim.

1 ad. Koon Tan May 1914. W=161 mm.; T~118 mm.; C = 23 mm; Tarsus = 43 mm. 
This bird which inhabits China has previously not been recorded from any country 
outside the Chinese limits.
