30 NILS GYLDENSTOLPE, ZOOLOGIGAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



33. Emberiza aureola. Pall. — The Yellow-breasted Banting. 



Jfi/pocentor aureolus: Muller p. 386. 



Emberiza aureola: Grant p. 70; Gyldenstolpe II; Gyldenstolpe III p. 171. 



$ Chum Too 2 / 5 1914. L = 136 mm.; W = 71 mm.; T = 57 mm.; C = 10 mm.; Tarsus = 19 mm. 

 — Irides: black. Bill: brown. Legs: brown. 



A winter visitor to Siarn. 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. Alaudidae. 



34. Mirafra microptera. Htjme. The Burmese Bush Lark. 



Mirafra microptera: Gyldenstolpe II; Gyldenstolpe III p. 171. 



J Koon Tan 28 / 4 1914. L = 140 mm.; W = 78 mm.; T = 44,5 mm.; C = 12 mm. — $ Sop Tue 

 2i /i 1914. L = 135 mm.; W — 75 mm.; T =? 43 mm.; C = 11, g mm. — Irides: blackisb brown. Bill: bom 

 colour. Legs: flesb colour. 



Two specimens collected in Northern Siarn 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 snitablc localities in the Northern 

 Districts. It only inhabits open jungles where the soil is sandy and where there is no 

 undergrowth. 



35. Mirafra assamica marionse. Stuart Baker. — Mrs. Williamson's Bush Lark.

In the Bulletin of the British Ornithologists' Club Vol. 35. Dec. 1915. Mr. E. C. 

 Stuart Baker has described a new subspecies of a Bush-lark under the name of Mirafra 

 assamica marionce. 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,o mm. or about the same as in microptera against a full 84,o 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
