A winter visitor to Siam. It generally goes about in small parties and is especially 
abundant in open country and on the rice-fields. During my stay in the Siamese Malaya 
I never observed it, but it probably occurs even there as it has been recorded from differ- 
ent parts of the Malay Peninsula. 
Fam. Alaudide.

Two specimens collected in Northern Siam ought to be referred to this species 
which outside Siamese Territory has previously only been obtained in Burma and Cochin 
China. It seems, however, to be fairly common on suitable localities in the Northern 
Districts. It only inhabits open jungles where the soil is sandy and where there is no 
undergrowth.

In the Bulletin of the British Ornithologists’ Club Vol. 35. Dec. 1915. Mr. E. C. 
Sruart Baker has described a new subspecies of a Bush-lark under the name of Mirafra 
assamica marione. The type specimens were obtained at Auythia a small town a few 
miles north of Bangkok. This new race differs from true Mirafra assamica Mc CLELL. 
»in being more brown and less grey above and paler below. The wings average about 
75,0 mm. or about the same as in microptera against a full 84,0 in assamica». 
The three specimens obtained by me at the neighbourhood of Koh Lak in the 
Siamese Malaya are probably to be referred to this new race. The wing measurements, 
however, are a little greater than recorded by Stuart BAKER. When labelling these speci- 
mens I at first determined them as being M. assamica though I noted some differences 
in the general tone of the colouration. The family Mirafra is a very difficult one and
