Sphenocercus pseudo-crocopus is an easily distinguished species and the only known 
species, with which it may be mistaken, is Crocopus phenicopterus viridifrons, because of 
its similar colouration. 
Unfortunately I did not take any records of the colour of the soft part of the bill 
and of the naked skin round the eye, but most probably these parts had the colour which 
has been painted by the artist (vide plate 3, fig. 1).

The Burmese Green Pigeon was sparsely distributed throughout the Northern 
Portions of the country, but it was never met with in real dense forests nor at any con- 
siderable altitude. It probably never ascends the higher hills, keeping exclusively to 
the plains. It occurs either single or in small flocks but never as some of the other kind 
of Green Pigeons in large flocks or even associating with them. 
Outside Siamese Territory it has been found in Burma as far south as Moulmein 
and to the southeast it reaches to Cochin China.

The Large Thick-billed Green Pigeon is apparently very rare in Siam, where it, 
however, even occurs as far north as to Lat. N. 19°. 
During my stay in Siam I only observed this beautiful species at two different occa- 
sions, but no specimens were preserved. However, Mr. E. E1IsrenHoFEr’s native collector 
obtained a fine specimen at the neighbourhood of Koon Tan during my stay there in 
April 1914.
