specimens either in size or colouration. Indeed, in so far as the 
material in the British Museum is concerned, I cannot divide the 
two races macrowra and tricolor, As far as [ can see the males of 
the two supposed races do not differ in the least from one another, 
and in both, the measurements of the wing vary from 89 to 
1OL mimi. 
Sclater’s swavis is named by him on a short tailed specimen 
with a small wing of 9L mm., which he presumes to be a female, 
but which had not been sexed by the collector. In the same way 
Sharpe presumed his specimens also to be females, though he has 
given no reasons for his presumption, and the specimens had never 
heen sexed. The males of swavis run from 97 to 102 mm., and the 
spot of black on the outermost tail feather is almost invariably 
very small,

The above series might really be called either citrina or 
innotatu, as they are half the one and half the other. Over prac- 
tically the whole of northern and central Siam G. ¢. citrine is the 
only form found, but in Peninsular Siam and Burma birds with, and 
birds without, the spot are found in about equal numbers until the 
extreme south of Siam is reached, when only the latter form is met 
with. On the other hand in eastern Burma there are well spotted 
specimens to be met with as far north as Karenni,
