A COLLECTION OF BIRD-SKINS FROM SIAM. 425 
the differences which he quotes as distinguishing it from its nearest 
allies are all more or less individual rather than sub-specifie in 
character except, perhaps, the “narrower dark bars on the wings 
and back” (? lower hack). 
Mr. Herbert’s three specimens and two others from Siam in 
the British Museum collection all agree with one another in one 
feature—rarely found in birds from elsewhere—the non-existence of 
any barring on the scapulars and upper back. They average also 
rather light in the tint of their plumage generally. In two of Mr. 
Herbert's birds there is no barring on the under plumage also, 
whilst in the third the bars are confined to the flanks only. Of the 
two Museum specimens one is immaculate beiow, the other more 
than usually profusely barred. 
All five birds have the centres of the throat feathers con- 
colorous with the breast; all have red shafts to the wing quills, but 
in two the bases of the shafts are marked with blackish. 
If it is eventually found that the Siamese Micropterni all 
have immaculate backs the name will have to be confined to this race ; 
otherwise, the name will. still hold good for birds from Siam and 
Burma. There is at present no name for the race north of Bangkok, 
(vide, Baker, Ibis 1919 p. 202) should this be separated,

All three of these birds are very typical brachyurus with 
dark throats, very black shafts to the wing quills, and densely bar- 
red lower plumage. They are, however, larger than most south 
Malayan birds, the wings being 117, 127 and 123 mm. respectively.
