Vernacular names. Nok-a-chap fon lepsan (Siam).
Description. The Siamese Bush-Lark differs from the preceding bird iu being less-ashy above and in having a distinct rufous tinge to the pale edgings of the feathers of this part; the pale nuchal markings are also better defined. It is a much smaller bird with a curiously long tarsus.
Colours of soft parts as in the other races.
Measurements, Wing 75 to 80 mm.; tail 40 to 45 mm.; tarsus 27 to 23 mm.; culmen 12 to 13 mm.
Distribution. Siam, Cochin China and Annam. A single specimen from Kyauk Phyon in Tenasserim also seems referable to this race and it is probable that all the birds in this region will prove to be the same.
Nidification. Not recorded.
Habits. Apparently similar to those of M. a. microptera. it is said to have a sweet little song and to assemble in some numbers, if not in actual flocks, during the Winter. It keeps, us fur as is. known, to quite open grass-lands and rice-fields.
