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



Among the mountains on the boundary between Siarn and Tenasserim on about 

 Lat. N. 12° I several times observed small parties of a Mynah, but if it was this species or 

 the allied G. j. javana Cuv. I am uiiable to ascertain because no specimens where procured 

 there. It, however, most probably was G. j. javana Cuv. because the birds seemed to 

 be rather large. 



16. Ampeliceps COronatus. Blyth. — The Yellow-crowned Mynah. 



Ampeliceps coronatus: Muller p. 388; Robinson & Kloss p. 68; Gyldenstolpe I p. 35; Gyldenstolpe II; Gylden- 

 stolpe III p. 168. 



<£ Rak Koh i6 /s 1914. L = 240 mm.; W =» 121 mm., T = 64 mm.; Bill from gape = 22 mm.; Tarsus 

 = 20 mm. — Irides: browu. Eyelid: reddish yellow. Bill: yellow. Legs: yellow. 



The Yellow-crowned Mynah is a fairly common inhabitat of the damp evergreen 

 forests of Northern Siarn, where it is generally met with in small parties keeping to the 

 highest trees. It is, however, quite tame and easy to obtain. 



Fani. Sturiiidse. 



17. Spodiopsar leucocephalus. Gigl. & Salvad. — Hume's Mynah.

 Culmen = 21 mm. — J* Koh Lak 2 /> a 1914. Length = 210 mm.; Wing = 120 mm.; Tail = 72, r> mm.; 

 Tarsus = 29 mm.; Culmen = 19 mm. — Iris: yellowish white. Bill: påle orange. Legs: yellowish brown. 



This species which has previously only been recorded from Cochin China and from 

 the neighbourhood of Tavoy on the boundary between Tenasserim and Siarn, was not 

 uncommon at the vicinity of Koh Lak, a small village situated at the coast of the Gulf 

 of Siarn and a little south of the latitude of Tavoy. 



When observed it was always mixed up in the flocks of the other Mynahs viz. 

 Sturnopastor floweri Sharpe and Graculipica nigricollis Payk. more seldom with Ae- 

 thiopsar grandis Moore. It was rather shy and always more difficult to get than its rela- 

 tives. It most often was observed in the open, park-like forests near the seashore, but 

 was sometimes found in the bamboo-forests though never far from villages. In the ever- 

 green jungles which cover the hill-tracts deviding Siarn and Tenasserim it was never ob- 

 served nor in any part of Northern or Central Siarn why its distributional area seems to be 

 only confined to the southern parts of the country. 



My specimens perfectly well agree with the descriptions in the litterature with the 

 exception that the j>rimaries are almost black. Only the tips and the innerwebs are 

 dusky brown. The basal part is pure white and of the same colour as the primary cov- 

 erts. The secondaries and the greater coverts are bronzy brown with some blackish 

 colour near the shafts. Sides of the body, flanks and tighs ashy; lower rump and 

 under tail-coverts påle fawn-buff.
