Klong Wahip, or more correctly Klong Wang Hip, is 
near Tung Song. 
Samkok is a little south of Ayuthia, in Central Siam. 
Maprit (also misspelt Marpit) is in the State of Patiyu, 
in about 11° N. latitude, between Mergui and Victoria Point 
(well-known ornithological localities), but on the east coast : 
Klong Bang Lai is near it. This portion of Siam I have 
called South-western Siam (vide ‘Ibis,’ January 1918). 
Siam is not a country whose minor features and villages 
are well known, and [ think that when typical localities of 
geographical races are in question obscure places should be 
accompanied by some indication of their situation. 
Mr. E. C. Stuart Baker sent the following communi- 
cation on the species Graucalus macei :— 
As with so many Indian birds, those of this species show 
a very great geographical variation in size. In the extren e 
North the birds attain their greatest size, and then gradually 
but steadily decrease in dimensions towards the South, until 
in Ceylon and the South of Burma and the Malay Peninsula 
we get the smallest specimens of all. 
In the present case we have birds in Ceylon with. an 
average wing-measurement of 145-4 mm., whilst in the 
North of India, from Simla to Bengal, we have a series of 
specimens with wings averaging 177°7 mm. 
It is impossible to keep as one species with no geo- 
graphical races birds with wing-measurements differing 
practically an inch and a half (62:1 mm.). At the same 
time it is difficult to know where to draw the line between 
the various subspecies when these are divided by size alone. 
There is, however, one feature which suffices at once 
to divide the Burmese from the Indian bird, and that is the 
fact that the adult female Indian bird—including those 
obtained in the Andamans—has the chin, throat, and 
upper breast barred, whereas those from Burma, Siam, 
and Hainan have these parts a uniform pale grey, much 
as in the male. It is true that in the British Museum
