* The “Green Pigeons” are removed by Jerdon from the larger Pigeons (Carpophaginee) and placed in a separate 
subfamily (Treroninse). Both are, however, essentially Fruit-Pigeons, and have precisely the same habits. The dis- 
tinctions pointed out, which consist in the thicker bill and shorter tail, are, in my opinion, only generic. I have, moreover, 
throughout my work (which is intended solely for the henejit of students of ornithology in Ceylon') avoided a complication 
of the subject by not taking sitMamilies into consideration more than I could possibly help. 
t This is only fully developed when the bird is adult. I have a young example of Osmotreron pompadora in which 
there is only an indication of it ; and the same holds good with other species of this group I have examined in the British 
Museum. It is, however, absent in Sphenocercus, the Kokla Green Pigeon, a curious Himalayan form with a pointed wedge- 
shaped tail.
