My collector subsequently procured two, in September 1917, in 
the district of Muang Wang, Northern Siam. 
2d imm. T. L. 295, 252 mm. W. 148,137. 
Family PHASIANID®—Pheasants, Partridges, ete., 
46. Arboricola brunneipectus Tick. The Brown-breasted 
Lill- Partridge. 
Arboricola brunneipectus, Gyldenstolpe, 1916, p. 156. 
Gyldenstolpe’s specimen was obtained at Doi Vieng Par, a 
mountain in North-western Siam, but it was, he states, too badly 
damaged to be preserved and could only be used for identification. 
He adds, “The Brown-breasted Hill-Partridge is only to be found 
among the mountains of Northern Siam.” 
In view of this statement it may be noted that Mr. K. G. 
Gairdner procured a specimen (identified by the British Museum) at Sai 
Yoke, Western Siam, in March 1915, at an elevation of 800 metres. 
Family HELIORNITHID&“-—finfeet. 
47. Heliopais personata (Gray). Zhe Masked Finfoot. 
1d. Muang Khlung, Chantaboon, South-eastern Siam, May 
1917. W. 268 mm. 
This specimen was procured by my collector, who, unfor- 
tunately, was incapable of noting the colours of the soft parts. 
Muang Khlung, the locality where it was obtained, is a coastal 
district about 12 miles south-east of the town of Chantaburi. 
Bonhote’s example from Jalor, Patani, in 1899 (P. Z. 8., 1901, 
p. 79), and that of Robinson from Koh Pennan, an island in the 
Bight of Bandon, in 1913 (Journ. Fed. Mal. States Mus., v, No. 3 
(1915), p. 141 ) appear to be the only previous records of this rare bird 
from Siam. Both these localities are in Peninsular Siam, on the 
opposite side of the Gulf to that on which my specimen was obtained. 
Family RALLIDM—Rails, Crakes, etc. 
48. Porzana pusilla (Pall.). Zhe Lastern Crake. 
Bonhote (P. Z. 8., 1901, p. 79) records a specimen obtained by 
the Skeat Expedition at Patelung, Peninsular Siam, in April 1899.
