The Common Mynah was rather abundant in or near villages especially in the 
northern parts of the country. It was, however, also observed in the Siamese Malaya as 
for instance at Koh Lak and its neighbourhood. They are always seen in pairs either 
jumping about on the ground or resting in a tree uttering their pretty song. They are 
often kept by the natives as a cage bird. 
In the »Catalogue of the Birds in the British Museum» vol. 13 p. 81 Dr. R. B. 
SHARPE states that the colour of the upper (misprint: under in the Cat.) tail-coverts is 
the same as the colour of the back. In the specimen obtained at Koon Tan the upper 
tail-coverts are, however, decidedly paler than the rest of the back, being brownish ashy 
with pale brown edges to the feathers. But perhaps this pale colouring may only be a 
sign of immaturity. 
Fam. Ploceide. 
25. Maunia atricapilla rubronigra. Hopas. — The Chestnut-bellied Munia. 
Munia atricapilla: Flower p. 323; Gyldenstolpe III p. 170. 
3 Chieng Hai ?/s 1914. L = 104 mm.; W = 51 mm.; T = 36 mm; C = 10,5 mm. — Irides: brown 
Bill: grey. Legs: plumbeous. 
I only observed this Munia near Chieng Hai and Chieng Sen, both small towns in 
Upper Siam. Even at these places they were rather rare. They occured in small parties 
of about 6 to 10 birds on the grassy plains outside the towns. Their food consists usu- 
ally of different kinds of seeds. 
The specimen obtained clearly belongs to the northern race which was named by 
Hopeson Munia rubronigra. It differs from the southern race, which is the typical 
Munia atricapilla ViEtLu. in having the abdomen, vent und under tail-coverts decidedly 
more blackish and in lacking the hoary-grey edges to the feathers of the mantle. 
26. Munia punctulata topela. Swrivu. 
& Chieng Hai '/, 1914. L = 120 mm.; W = 54,5 mm. T = 48,5 mm.; C = 10,7 mm. — Irides: 
brown. Bill: black. Legs: plumbeous. 
At the neighbourhood of Chieng Hai, one of the most important towns of Upper 
Siam this species was rather common on the large grassy plains which cover such an ex- 
tensive area of land outside this town. It was also observed a few times in bamboo- 
forests in several other parts of Northern Siam.
